Nations in Debt

The last two blogs dealt with insurance against catastrophic damage that is associated with the accelerating impacts of climate change (September 12th and September 19th). Both blogs were focused on the United States. The first was focused on the increasing withdrawal of private insurance companies from vulnerable markets, while the second blog dealt with the complex state of federal contributions to supplement local insurance, mainly through FEMA. Recent coverage of the increasing impact of climate change focused on the destruction of two relatively small towns: Lahaina in Maui, Hawaii, destroyed by uncontrolled wildfire, and Derna in Libya, destroyed by an uncontrolled flood that was amplified by the destruction of two ill-maintained dams. The Lahaina destruction resulted in the death of about 100 people while that in Libya resulted in the death of thousands. Lahaina is in the US and expecting help from the US federal government. Derna is not in the US and the Libyan government is basically nonexistent. Both stories disappeared from the news after only a few days. The survivors from Lahaina will slowly try to recuperate with the help of local and federal funds. What will the survivors of Derna do?

Obviously, Derna and Libya are not alone. Recently, the NYT published an article on the difficulties that most developing countries face in trying to adapt to the increased threats of climate change. The article’s emphasis was on the situation in Ghana, with the full realization that it is common to most developing countries. Below is the most general citation from that article:

            Crisis and Bailout: The Tortuous Cycle Stalking Nations in Debt

The debt load for developing countries — now estimated to top $200 billion — threatens to upend economies and unravel painstaking gains in education, health care and incomes. But poor and low-income countries have struggled to gain sustained international attention. In Ghana, the I.M.F. laid out a detailed rescue plan to get the country back on its feet — reining in debt and spending, raising revenue and protecting the poorest — as Accra negotiates with foreign creditors.

Still, a nagging question for Ghana and other emerging nations in debt persists: Why will this time be any different?

The latest rescue plan outlined for Ghana addresses key problems, said Tsidi M. Tsikata, a senior fellow at the African Center for Economic Transformation in Accra. But so did many of the previous ones, he said, and still crises recurred.

The last time Ghana turned to the fund was in 2015. Within three years, the country was on its way to paying back the loan, and was among the world’s fastest-growing economies. Ghana was held up as a model for the rest of Africa.

Details about the global debt situation are shown in Figure 1.

Bar graph of debt by country, divided into government, household, and corporate sectors

Figure 1 – Total debt by country  (Source: Seeking Alpha)

On the scale of Figure 1, it seems that there is not much difference between rich and poor in terms of the ratio between the various debt forms and the GDP of the countries (a factor slightly greater than 2 between the largest debt ratio, Japan, and the smallest one, Brazil). However, one important factor is missing in the figure – the strength of the currencies of the various players. If a disaster strikes the United States, (issues with inflation aside) the US can just print more money to satisfy immediate needs. Brazil and other developing countries cannot do the same.

Figures 2 and 3 show two important factors in play that should convince rich countries to help poor countries face the destructive impacts of climate change.

Figure 2 shows the cumulative global contributions to carbon emissions, the main driver of today’s changes in atmospheric chemistry, and therefore the main culprit for accelerating climate change. The two leading contributors to this accumulation are the US and the European Union.

Figure 3 – Share of energy consumption by fuel (Source: Visual Capitalist)

Global players such as the UN do not have the effective enforcement power required for reparations. Figure 3 shows the energy/fuel consumption of fuels for a list of countries and blocks of countries that roughly correspond to the G20 country collections. The largest coal consumers are developing countries (South Africa, China, India, etc.). The atmosphere is global and carbon dioxide (the most prevalent greenhouse gas) spreads easily throughout. Therefore, a good self-empowering argument can be raised for rich countries to help poor countries in the adaptation and mitigation of climate change. Doing so will actively participate in the global energy transition away from using coal, the most polluting energy source.

The largest threat that is starting to convince rich countries that it is in their self-interest to help developing countries confront climate change, comes from the unavoidable results of failure. This is also transparent in the fate of Libyan survivors of the deadly floods in Derna. The threat is the uncontrolled increase in environmental refugees who feel that their livelihoods and even lives are being destroyed. They find their countries unable to confront the destruction, forcing them to try to search for shelter in countries with better chances of confronting the danger.

I wrote about this issue in previous blogs (see April 3, 2018) and every semester I show my students a film about the issue made by the American army (The Age of Consequences) that shows that the border security of the rich countries is threatened by an increasingly large number of people who feel no longer safe in their own country.

For the first time, last year, in the COP27 global climate meeting, this issue took center stage (see November 22, 2022 blog). It is a certainty that this issue will be central in the coming COP28 conference in the United Arab Emirates.

There are two international organizations that have it in their charters to help developing countries confront global economic threats, these are the World Bank and the IMF (International Monetary Fund). The next blog will focus on these organizations.

Stay tuned.

Federal Assistance for Disasters

Last week’s blog was focused on the observations that private insurance companies are now running away from insuring for natural disasters, mainly because they lose money in this business. It was mentioned there that Florida, having its share of these disasters, confronted this issue by spreading the burden among all its citizens, instituting what some call a “hurricane tax.” This blog is trying to address the issue of the role of the federal government in insuring against disasters.

As was mentioned in last week’s blog, we are now seeing an acceleration in both the frequency and costs of such disasters:

By NOAA’s tally, the events so far this year have caused 253 direct and indirect fatalities and produced more than $57.6 billion in damage — a figure that probably will rise as officials continue to document losses from Tropical Storm Hilary in Southern California and drought that persisted across parts of the Midwest and South.

The acceleration is not confined to the US. The largest recent impact was probably observed in Libya, where the Mediterranean storm Daniel almost wiped out the eastern Libyan city of Derma (125,000 inhabitants). By the time I wrote this blog on Friday, the number of deaths in Libya exceeded 10,000, with many still missing:

Spokesperson of the interior ministry Lieutenant Tarek al-Kharraz on Wednesday told the AFP news agency that 3,840 deaths had been recorded in the Mediterranean city so far, including 3,190 who have already been buried. Among them were at least 400 foreigners, mostly from Sudan and Egypt.

Meanwhile, Hichem Abu Chkiouat, minister of civil aviation in the administration that runs eastern Libya, told the Reuters news agency more than 5,300 dead had been counted so far, and said the number was likely to increase significantly and might even double.

Derna Mayor Abdulmenam al-Ghaithi told Saudi-owned Al Arabiya television the estimated number of deaths in the city could reach between 18,000 to 20,000 based on the number of districts destroyed by the flood.

In the US, the federal responsibility for providing support rests on the shoulders of FEMA (Federal Emergency Administration Agency). Below is some background from Wikipedia that summarizes the role and history of this agency:

The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979.[1] The agency’s primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state’s gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle Columbia in the 2003 return-flight disaster.

While on-the-ground support of disaster recovery efforts is a major part of FEMA’s charter, the agency provides state and local governments with experts in specialized fields, funding for rebuilding efforts, and relief funds for infrastructure development by directing individuals to access low-interest loans, in conjunction with the Small Business Administration. In addition to this, FEMA provides funds for response personnel training throughout the United States as part of the agency’s preparedness effort.

In a recent series of reviews, the Brookings Institute examined the effectiveness of FEMA, concluding with some suggestions for improvements. Below, I will focus on the second and third of these posts. The second post focuses on the extent of the current working of FEMA. The present dynamics are shown in Figure 1 and the recent history of the support that went through FEMA is shown in Figure 2.

Figure 1 – The FEMA process (Source: Brookings Institute)

Figure 2 – Recent history of disaster funding in the US (CDBG-DR- Community Development Block Grant – Disaster Recovery) (Source: Brookings Institute)

The third post shows the complexities of the present system and ends with some suggestions for improvements. Figure 3 shows the details of these complexities:

The current federal disaster management structure is labyrinthian: Five “mission area frameworks” spread across 32 “core capabilities” that involve dozens of federal programs in multiple cabinet and non-cabinet agencies, each with its own support function and coordinating role.

On the FEMA website, the five planning frameworks mentioned above are: prevention, protection, mitigation, response, and disaster recovery.

Figure 3 – the many federal entities involved in disaster funding

Some of the reasons for these complexities are summarized below:

There are many reasons for this complicated structure. First, each program’s remit is defined in statute, and incremental reforms and layering of processes have resulted in a behemoth of bureaucracy. For example, CDBG-DR is defined by the statutes associated with the 1974 CDBG program for urban development projects—not disaster recovery. The role and mission of each agency is defined by Congress, working through multiple legislative subcommittees that handle authorization, oversight, and appropriations. Generally, the programs were not defined with a holistic vision for federal disaster policy, let alone an integrated knowledge of the implementation challenges associated with each federal function relevant to disasters.

Political instabilities are primary triggers for government inabilities to help with any kind of disaster, additionally accelerating damage by failing to mitigate or adapt to probable future disasters. This is true not only for countries with their own federal structures but also internationally, when disasters strike poor countries that have serious difficulties helping themselves. This is visible in the latest disaster in Libya, where animosities between the country’s eastern, military government and western, internationally recognized government, have frozen the county for the last 10 years, preventing maintenance and ultimately leading to the collapse of the two dams. The ensuing floods were largely responsible for the destruction of Derma and the resulting deaths of thousands.

In the US, a similar political contest is now threatening to freeze government funding:

The new fiscal year (FY) begins on October 1, 2023, and Congress has so far enacted none of the 12 appropriations bills setting discretionary spending levels. Lawmakers have until midnight on the final day of the fiscal year – September 30 – to enact legislation to fund the programs covered by the appropriations process, or the government will shut down. A continuing resolution (CR) to allow lawmakers more time to complete work on spending bills is likely to be considered. A shutdown in FY 2024 would affect all federal activities covered by discretionary appropriations, as opposed to the most recent FY 2019 shutdown that began in late 2018 and extended into early 2019 that affected only departments and agencies covered by the seven appropriations bills that Congress had not yet enacted.

The funding freeze will put a stop to supplemental financing of FEMA. That will prevent the agency from helping with recent disaster areas in Hawaii and Florida, as well as stopping any help to Libya, Morocco, Ukraine, and whatever comes next.

The Future of Insurance

(Source: Accomsure)

The last two blogs focused on the money that we need to spend now to try to mitigate the increasing impacts of climate change on all of us. The example that I used was the recent devastating impacts of the fires in Maui, Hawaii, and the factors that could have lessened the damage, namely: water availability and burying power lines. In the meantime, hurricane Idalia hit Florida hard and hurricane Lee strengthened in the Atlantic to become a category 5, with a track that includes some probability that it will hit my home (NYC).

At the same time, I got an email from a reader (Erika Reid) of my recent blogs, asking me to focus on insurance policies. I responded that this was exactly my plan. It turns out that she is an “influencer” for considering the impacts of disasters on insurance companies. Below is a brief excerpt of what her site has to say about the impact of climate change. I emphasized the most dramatic sentence because it illustrates just how big the effects of the problem are:

As the effects of climate change have worsened, insurance companies have responded by increasing the cost of coverage — or pulling out of markets entirely. Farmers Insurance, the nation’s seventh largest auto coverage provider, announced in July that it will no longer offer policies in Florida. The insurer cited the financial risk of hurricanes as a significant reason. Farmers’ decision affects roughly 100,000 people, according to CNN.

As the warming climate exacerbates wildfires, floods and other natural disasters, car insurance companies are likely to see a greater number of comprehensive claims. Car insurance will get even more expensive, and more companies may follow Farmers’ lead. The insurance providers that remain on the market would have an incentive to charge more in higher-risk areas.

“Unless we have more auto insurers competing, the general auto insurance premiums will stay higher for a long time,” Yao said.

I wrote about the impacts of climate change on insurance policies in previous blogs. Put “insurance” into the search box and you will get several entries. One example is titled “We Are Not Prophets II – Back to Deniers and Skeptics and Forward to Insurance(August 20, 2012). I opened that blog with a citation from my book that applies just as well today as it did more than 10 years ago:

Can we insure the survival of the planet as a habitable environment? If the answer is yes, then who will pay the premium?  If climate-change is just a big catastrophic event, then the mechanism of financial preparation should not be much different than the insurance of present catastrophic events. The trouble is that we are not very good at insuring catastrophic events. The present situation of flood insurance is a good example. In the United Kingdom, flood insurance is provided by private insurance, but in the United States it comes through a federally backed insurance system. In France and Spain flood insurance is bundled with other natural perils into a national pooling arrangement, and in Holland it is completely unavailable. The insurance industry is heavily involved in the debate on climate change. “Climate Change is a clear business opportunity for the insurance industry,” declared Shinzo Abe, former Prime Minister of Japan, at the Geneva Association meeting in Kyoto on 29 May 2009 [The Geneva Reports, www.genevaassociation.org, “The Insurance Industry and Climate Change – Contributions to the Global Debate”, No. 2, July 2009].

This is what is happening today:

From devastating hurricanes and wildfires to catastrophic floods and tornadoes, natural disasters are increasing in frequency and cost. According to the NOAA National Centers for Environmental Information (NCEI), over the past ten years, 152 disasters caused at least $1 billion dollars of damage per occurrence. This puts the total cost of billion-dollar disasters to more than $1.1 trillion over the past ten years. Climate change plays a major role in the frequency and intensity of severe weather. In addition to factors like insufficient building codes, increased population in vulnerable areas and inflation, the death tolls and financial cost of extreme storms may continue to rise every year. Homeowners bear the brunt of the financial burden and need to have adequate insurance coverage or risk paying out of pocket to rebuild their homes.

Major insurers say they will stop covering damage caused by hurricanes, wind, and hail for property along coastlines and in wildfire country. Again, I have emphasized the sentences that describe the biggest impacts:

In the aftermath of extreme weather events, major insurers are increasingly no longer offering coverage that homeowners in areas vulnerable to those disasters need most.

At least five large U.S. property insurers — including Allstate, American Family, Nationwide, Erie Insurance Group and Berkshire Hathaway — have told regulators that extreme weather patterns caused by climate change have led them to stop writing coverages in some regions, exclude protections from various weather events and raise monthly premiums and deductibles.

Major insurers say they will cut out damage caused by hurricanes, wind and hail from policies underwriting property along coastlines and in wildfire country, according to a voluntary survey conducted by the National Association of Insurance Commissioners, a group of state officials who regulate rates and policy forms.

Insurance providers are also more willing to drop existing policies in some locales as they become more vulnerable to natural disasters. Most home insurance coverages are annual terms, so providers are not bound to them for more than one year.

Examples of this year’s impacts on states and companies can be found below :

What’s driving this upheaval? Climate change. Extreme weather, including devastating California wildfires and costly Gulf coast hurricanes, are forcing insurers to reassess their risk tolerance.

And many are simply deciding the increased risk of extreme weather combined with rising construction costs due to inflation make offering insurance in at least some locations untenable.

The problem isn’t confined just to coastal areas of the country. As Steve Bowen, chief science officer at global reinsurance broker Gallagher Re told Axios last month, “this is a 50-state problem as insurers are being forced to re-assess their risk tolerance as climate change leads to more common and severe extreme weather events.

Believe it or not, we could be facing a future where certain parts of the country are literally uninsurable or where insurance is affordable only for the wealthy.

This last sentence summarizes the issue. Many of the worsening impacts of climate change are taking place in Republican-governed states in the Southeast US such as Florida, Texas, and the Carolinas. Florida is compensating for the destructive impacts of hurricanes with what some of the media call a “hurricane tax”:

In Florida, it won’t just be those with homes and businesses hit directly by Hurricane Idalia who might be stuck picking up the pieces. Thanks to a broken home insurance market, a particularly bad hurricane could spread financial fallout throughout the state, leaving residents from Pensacola to Key West stuck paying repair bills for years.

Beset by hurricanes made more severe and more frequent by climate change, as well as rampant fraud and tides of frivolous lawsuits, dozens of insurers in the state have closed up shop or stopped selling new home insurance policies in the state in recent years. (Farmers became the most recent big insurer to pull out of the state last month). Residents have increasingly turned to Citizens Property Insurance Corporation, a public entity established by the Florida government as the state’s so-called “insurer of last resort” for people unable to find affordable rates from private insurers. For more and more residents, though, Citizens is becoming the first and only option, especially for those with coastal homes at particular risk from hurricanes. In 2019, Citizens had about 400,000 home insurance policies on its books; today, it has more than 1.3 million, about twice as many as the state’s next-largest insurer.

Yet, the Republican governors of these states and the Republican party still refuse to acknowledge our collective culpability and our ability to mitigate future climate change-driven disasters. One example of this reasoning is a fictional scenario outlined in the WSJ. They refuse to acknowledge that human culpability does not manifest itself in the variability of the weather (hot vs. cold) but, instead, by amplifying the frequency and intensity of extreme events. It’s the victims of these events who need insurance.

The next blog will focus on the role of the federal government in mitigating the impacts of climate disasters.

Utility Pricing: We Will All Have to Pay More

Figure 1 – Above-ground high-power lines in the Netherlands

Below, I’m including two short paragraphs from an earlier blog (December 10, 2019) about the ignition of the wildfires in California:

Both situations started with tinderbox conditions (whether metaphorical or more physical) PG&E is accused of being the random neutron that set off these large fires. This accusation triggered massive lawsuits that led to a temporary bankruptcy. The company’s remedy was to turn off the lights for massive numbers of its customers.

There was another solution that really should have been implemented long ago: utility companies ought to have buried the electrical wires underground, effectively insulating them from the dry countryside. As usual, the obstacle to this massive undertaking was cost

Almost the same can be written about most wildfires, including the recent one in Maui, Hawaii.

And like in California, the Hawaiian power company (Hawaiian Electric) is trying to fight back—this time by denying responsibility:

Even before the inferno that engulfed the Maui resort of Lahaina is fully contained, local officials and Hawaii’s leading utility are at odds over a fundamental question: Did a single fire break out in the hills overlooking the town on the fateful day, or were there two?

The answer may be crucial to establishing the cause of the disaster and the liability for it.

The utility, Hawaiian Electric, acknowledged for the first time late Sunday that its power lines, buffeted by uncommonly high winds, fell and ignited a fire early on the morning of Aug. 8.

But the company said that by 6:40 a.m. — minutes after the first reports of a fire — the windstorm had caused its lines in the area to shut off automatically. And it noted that the fire was later reported “100 percent contained” by the Maui County Department of Fire and Public Safety, which left the scene and later declared that the fire had been “extinguished.”

On the open forum site Quora, Avadhesh Khanna answered the question of, “Which country doesn’t have overhead transmission line system?” While his English grammar is not great, his comment contains relevant, important, details about powerlines:  

First of all, question is very generic one. Let me eleborate! There are basically two part of power transmission. One major transmission from source/grid/large sub station to small sub station & industries (HV/MV) and second is ‘distribution’ to household blocks (LV). In former one, they need to have overhead transmission line because cost of underground cables is very high and getting insulation of that voltage and doing construction is not very economical.

Whereas in later case, low voltage distribution is required for house blocks. As human safety is very important, so rich countries like US, England can afford to put underground cables for later case (underground cabling is always costlier than overhead). But developing countries like India cannot afford to have underground cable, so they prefer overhead transmission, human safety is compromised.

In nutshell, no country is having absolute overhead or underground cable. It’s hybrid!

Now a days, developing countris are moving towards underground for houses/blocks but HV transmission is still overhead.

It’s majorly about money !

The general issue of undergrounding, or burying power lines, is summarized on Wikipedia. I have emphasized the issues of cost, as listed under Disadvantages:

In civil engineeringundergrounding is the replacement of overhead cables providing electrical power or telecommunications, with underground cables. It helps in wildfire prevention and in making the power lines less susceptible to outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the aesthetic quality of the landscape without the powerlines. Undergrounding can increase the capital cost of electric power transmission and distribution but may decrease operating costs over the lifetime of the cables.

Advantages[edit]

  • Less subject to damage from severe weather conditions (mainly lightning, hurricanes/cyclones/typhoons, tornados, other winds, and freezing)
  • Decreased risk of fire. Overhead power lines can draw high fault currents from vegetation-to-conductor, conductor-to-conductor, or conductor-to-ground contact, which result in large, hot arcs.[2]
  • Reduced range of electromagnetic fields(EMF) emission, into the surrounding area. However, depending on the depth of the underground cable; greater EMF may be experienced on the surface.[3] The electric current in the cable conductor produces a magnetic field, but the closer grouping of underground power cables reduces the resultant external magnetic field and further magnetic shielding may be provided. See Electromagnetic radiation and health.
  • Underground cables need a narrower surrounding strip of about 1–10 meters to install (up to 30 m for 400 kV cables during construction), whereas an overhead line requires a surrounding strip of about 20–200 meters wide to be kept permanently clear for safety, maintenance and repair.
  • Underground cables pose no hazard to low-flying aircraft or to wildlife.

Underground cables have a much reduced risk of damage caused by human activity

Disadvantages[edit]

An underground cable marker. Markers are put at regular intervals to show the route and warn of the hazard of digging into the cable.

  • Undergrounding is more expensive, since the cost of burying cables at transmission voltages is several times greater than overhead power lines, and the life-cycle cost of an underground power cable is two to four times the cost of an overhead power line. Above-ground lines cost around $10 per 1-foot (0.30 m) and underground lines cost in the range of $20 to $40 per 1-foot (0.30 m).[9]In highly urbanized areas, the cost of underground transmission can be 10–14 times as expensive as overhead.[10] However, these calculations may neglect the cost of power interruptions. The lifetime cost difference is smaller for lower-voltage distribution networks, on the range of 12-28% higher than overhead lines of equivalent voltage.[11]
  • Whereas finding and repairing overhead wire breaks can be accomplished in hours, underground repairs can take days or weeks,[12]and for this reason redundant lines are run.
  • Underground cable locations are not always obvious, which can lead to unwary diggers damaging cables or being electrocuted.
  • Operations are more difficult since the high reactive power of underground cables produces large charging currents and so makes voltage control more difficult. Large charging currents arise due to the higher capacitance from underground power lines and thus limits how long an AC line can be. In order to avoid the capacitance issues when undergrounding long distance transmission lines, HVDC lines can be used as they do not suffer from the same issue.[13]
  • Whereas overhead lines can easily be uprated by modifying line clearances and power poles to carry more power, underground cables cannot be uprated and must be supplemented or replaced to increase capacity. Transmission and distribution companies generally future-proof underground lines by installing the highest-rated cables while being still cost-effective.
  • Underground cables are more subject to damage by ground movement. The 2011 Christchurch earthquake in New Zealand caused damage to 360 kilometres (220 mi) of high voltage underground cables and subsequently cut power to large parts of Christchurch city, whereas only a few kilometres of overhead lines were damaged, largely due to pole foundations being compromised by liquefaction.
  • As underground repair and check up require street digging, it creates patches and potholes, leading to bumpy and unsafe ride for cars and bicycles. Utility work also increase lane closure which leads to the traffic jam and increasing cost of resurfacing work by the local government.[14][15]

The advantages can in some cases outweigh the disadvantages of the higher investment cost, and more expensive maintenance and management.

International abundance (Same Wikipedia site)

All low and medium voltage electrical power (<50 kV) in the Netherlands is now supplied underground.

In Germany, 73% of the medium voltage cables are underground and 87% of low voltage cables are underground. The high percentage of underground cables contributes to the very high grid reliability (SAIDI < 20).[19] In comparison, the SAIDI value (minutes without electricity per year) in the Netherlands is about 30, and in the UK it is about 70.

Most electrical power in Japan is still distributed by aerial cables. In Tokyo’s 23 wards, according to Japan’s Construction and Transport Ministry, just 7.3 percent of cables were laid underground as of March 2008.

Wikipedia also includes a detailed list of such underground and submarine cables.

In most cases, the main disadvantage is the price. The price difference between keeping the transmission lines overground and burying them underground is shown in Figure 2.

As shown in the California case (temporary bankruptcy after one charge of igniting a major wildfire) and the expected charges in Hawaii, the inclusion of expected damage from hanging wires will probably change the accounting.

Water Pricing: We Will All Have to Pay More

Figure 1 – The price of water in some of the world’s largest cities (Source: Municipal water utilities, Oxford Analytica)

Figure 1, above, shows what seems to be the random distribution of the price of water in some of the largest cities from developed, developing, and intermediate-income countries. All of these cities are either located on the shore of an ocean or surround a large river that is directly connected to an ocean. Yet, the water pricing that its citizens enjoy seems random.

The most devastating disaster many of us are focusing on these days is the August 8th, climate-related wildfire destruction of Lahaina in Maui, Hawaii. As of yesterday, the death toll had reached 115, with 388 still unaccounted for. The sorrow is now being converted into anger that the destruction was a consequence of a predictable disaster that we have no idea how to handle. As one NYT article put it, “Maui Knew Dangerous Wildfires Had Become Inevitable. It Still Wasn’t Ready.” Furthermore, many of us think that now, this kind of disaster can happen everywhere, and we’d better take some lessons from it to minimize the impact.

The Maui disaster comes in the midst of record-breaking global heatwaves that the NYT describes in the following way (Extreme Weather Hits Around the World as Global Temperatures Rise):

Not all of the extreme weather events can be immediately attributed to climate change. But they reflect the hazards that much of the world needs to prepare for as El Niño, a natural weather pattern that can play out over several years, aggravates the weather extremes fueled by the burning of fossil fuels.

My “cherry-picked” comment is to emphasize the words “immediately attributed.” I will expand on this in a future blog. I will also try to expand in a future blog on what we know about the anthropogenic (human-caused) impacts of El Niño.

Two of my favorite reporters from The New York Times comment on these developments, and others, in their recent dialogue (Opinion: These Aren’t the Darkest Years in American History, but They Are Among the Weirdest). Their emphasis, like most of the rest of the press and the social networks, is on the accumulating issues with ex-president Trump and his wishes to be president again. But before going there, they start with their take on Maui and Lahaina. I have “cherry-picked” a few paragraphs from their dialogue:

Gail Collins: Maui is going to be hard for any of us to forget. Or, in some cases, forgive. There are certainly a heck of a lot of serious questions about whether the folks who were supposed to be responsible did their jobs.

Bret: There’s a story in The Wall Street Journal that made me want to scream. It seems Hawaiian Electric knew four years ago that it needed to do more to keep power lines from emitting sparks, but it invested only $245,000 to try to do something about it. The state and private owners let old dams fall into disrepair and then allowed for them to be destroyed rather than restoring them, leading to less stored water and more dry land. And then there was the emergency chief who decided not to sound warning sirens. At least he had the good sense to resign.

Gail: But let’s look at the way bigger issue, Bret. The weather’s been awful in all sorts of scary ways this summer, all around the planet. Pretty clear it’s because of global warming. You ready to rally around a big push toward environmental revolution?

Bret: I’m opposed on principle to all big revolutions, Gail, beginning with the French. But I am in favor of 10,000 evolutions to deal with the climate. In Maui’s case, a push for more solar power plus reforestation of grasslands could have made a difference in managing the fire. I also think simple solutions can do a lot to help — like getting the federal government to finance states and utilities to cover the costs of burying power lines.

Gail: Yep. Plus some more effortful projects to address climate change, like President Biden’s crusade to promote electric cars and an evolution away from coal and oil for heat.

Bret: The more I read about the vast mineral inputs for electric cars — about 900 pounds of nickel, aluminum, cobalt and other minerals per car battery — the more I wonder about their wisdom. If you don’t believe me, just read Mr. Bean! (Or at least Rowan Atkinson, who studied electrical engineering at Oxford before his career took a … turn.) He made a solid environmental case in The Guardian for keeping your old gas-burning car instead of switching to electric. But I’m a big believer in adopting next-gen nuclear power to produce a larger share of our electric power needs. And I’m with you on moving away from coal.

The unfortunate thing about both reporters waving their favorite remedies for climate change is that those have very little to do with the direct consequences of what happened in Lahaina and other similar impacts of the destructive forces that climate change brings us. When a disaster like this strikes, an often immediate reaction is to search for culprits to blame. Hanging wires from electric utilities are common candidates (see the situations in destructive fires in California (November 26, 2019). In Maui, it got worse because the fire hydrants turned out to be dry – there was no water to fight the flames. It turns out that this situation had been predicted and could have been remedied by creating water storage facilities to be reserved for that purpose as insurance. This was not done because of fear that it would impact agriculture.

Water stress and hanging utility wires have become connected to the loss of control of wildfires. To make sure that such issues are not repeated, we will all need to pay more for both utilities. This blog focuses on water. Next week’s blog will focus on hanging wires.

I addressed climate-change-triggered water stress in earlier blogs, emphasizing the local aspect of water stress. After all, in a world where 70% of the surface is covered by oceans, we cannot claim to be lacking water (reminder – Maui and all Hawaiian Islands are surrounded by the Pacific Ocean). What we can have is stress related to freshwater availability and the shifts and changes in intensity of the water cycle.

Here, in the context of the water issues in Maui, I will focus on the important role that agriculture plays in water use and how the pricing of water varies across the planet.

Figure 2 shows global water use by sector. Agriculture is in the lead. However, the percentage of water use in agriculture is not equally distributed.

Figure 2 – Global water use by sector (Source: OECD)

Figure 3 shows the global distribution. Developing countries bear most of the heaviest use. A good place to start revisiting the issue is in the March 4, 2014 blog, where I describe the holistic effort that Israel is putting into addressing the issue.

Figure 3 – Agricultural share of water withdrawals, 2019 (Source: Our World in Data)

The Israeli effort is focused on recycling water locally and desalination of sea water. These processes cost money and access to sea water. Hawaii is a state of the US, the largest rich country in the world, surrounded by the water of the Pacific Ocean. If one of our states could not be prepared for such water stress, who could? Figure 4 shows that a significant fraction of the world is desperately lacking access to safe water.

In an earlier blog (July 4, 2023), I showed what another state in the US, Arizona, is doing to prepare: it’s coming to an agreement with Mexico and Israel to construct a desalination plant in Mexico. The idea is to serve Arizona and limit new construction in selected areas until the water situation improves. The poor countries, such as those in Africa, don’t have that option. If the rich countries refuse to help them secure access to safe water, they may refuse to cooperate in climate change mitigation. This could mean refusing to cooperate in global efforts to lessen the probability that what just happened to Lahaina will engulf the whole planet.

Back to Cherry-Picking and Political Feedback

In the last few blogs, I was busy summarizing our trip to Australia. It’s time to return to the real world.  The dominating features in the news are the various legal issues of ex-president Trump and his acolytes and the devastating wildfires in Maui that destroyed Lahaina. More than 100 people have been reported dead  and around 1,000 are still missing, so it is predicted that the number of fatalities is going to increase substantially. As strange as it seems, the two issues are related. Also taking place “now” is a series of warnings about the threats of global changes—namely, the anthropogenic (human-caused) changes in the atmospheric chemistry that directly result in temperature increase:

Weeks of scorching summer heat in North America, Europe, Asia and elsewhere are putting July on track to be Earth’s warmest month on record, the European Union climate monitor said on Thursday, the latest milestone in what is emerging as an extraordinary year for global temperatures.

Last month, the planet experienced its hottest June since records began in 1850. July 6 was its hottest day. And the odds are rising that 2023 will end up displacing 2016 as the hottest year. At the moment, the eight warmest years on the books are the past eight.

“The extreme weather which has affected many millions of people in July is unfortunately the harsh reality of climate change and a foretaste of the future,” Petteri Taalas, the secretary general of the World Meteorological Organization, said in a statement. “The need to reduce greenhouse-gas emissions is more urgent than ever before.”

It’s hot almost everywhere and the symptoms are predictable. I will return to these in greater length in future blogs. Below is a short list:

Sea ice is melting at an accelerated pace around Antarctica and Greenland. This is bound to accelerate land ice melting in these locations. Both factors are predicted to accelerate global sea level rise.

More than 90% of the increase in solar heat is absorbed by the Earth’s oceans. This means that ocean temperatures are also rising at an accelerated pace, as can be seen in Figure 1. The extra heat is sure to accelerate extreme weather events such as hurricanes and tornadoes and prolong the impact of climate change even after we have control of greenhouse gases.

Figure 1 – Ocean temperatures by year (Source: ERA5, C3S/ECMWF via BBC)

This rise in water temperature and influx of fresh water is causing a major decrease in ocean currents, which will have a strong impact on global heat flow. That, in turn, will have a strong impact on global weather.

As we will see below, considerable progress has been made in mitigating and adapting to the anthropogenic forces that trigger devastating consequences of climate change. Even so, all of that progress can be reversed through a change of governments. One concrete example from the US is sufficient to demonstrate the risk:

During a summer of scorching heat that has broken records and forced Americans to confront the reality of climate change, conservatives are laying the groundwork for a future Republican administration that would dismantle efforts to slow global warming.

The move is part of a sweeping strategy dubbed Project 2025 that Paul Dans of the Heritage Foundation, the conservative think tank organizing the effort, has called a “battle plan” for the first 180 days of a future Republican presidency.

The climate and energy provisions would be among the most severe swings away from current federal policies.

The plan calls for shredding regulations to curb greenhouse gas pollution from cars, oil and gas wells and power plants, dismantling almost every clean energy program in the federal government and boosting the production of fossil fuels — the burning of which is the chief cause of planetary warming.

However, our new era “enjoys” an avalanche of communication. It is up to us to pick and choose. None of us has the time or interest to follow all the available news. What we often tend to follow are sources that fit our worldview. If we are living in democratic countries in which periodically, we choose our governments, we likely cherry-pick information that strengthens our worldview and justifies our preconceived priorities. This practice provides a positive feedback loop iiiand serves to strengthen our polarization. A good example of all of this took place on the morning of Sunday, August 12th.

I was still busy with the blogs that summarized our Australian trip. However, when we are home, our routine for Sunday morning is to read the New York Times, followed by breakfast. On Sunday, the paper usually arrives a bit late, so we often supplement it with the digital edition on our iPads. On August 12th, I saw in the digital edition of the NYT a large survey of the status of our energy transition, summarized in three articles. Each article was introduced in the following way:

This is the first article in a three-part series examining the speedchallenges and politics of the American economy moving toward clean energy.   Aug 16, 2023

It mentions August 16, 2023 with no explanation.

This series was clearly “bread and butter” for me, and for this blog, but not necessarily for everybody else, my wife included. Below are the “cherry-picked” citations that give the essence of the three articles:

Energy Transition: Speed

“We look at energy data on a daily basis, and it’s astonishing what’s happening,” said Fatih Birol, the executive director of the International Energy Agency. “Clean energy is moving faster than many people think, and it’s become turbocharged lately.”

More than $1.7 trillion worldwide is expected to be invested in technologies such as wind, solar power, electric vehicles and batteries globally this year, according to the I.E.A., compared with just over $1 trillion in fossil fuels. That is by far the most ever spent on clean energy in a year.

Those investments are driving explosive growth. China, which already leads the world in the sheer amount of electricity produced by wind and solar power, is expected to double its capacity by 2025, five years ahead of schedule. In Britain, roughly one-third of electricity is generated by wind, solar and hydropower. And in the United States, 23 percent of electricity is expected to come from renewable sources this year, up 10 percentage points from a decade ago.

Figure 2 – The rate of solar and wind power adaptation in the three most populous countries and the EU (Source: The Energy Institute’s 2023 Statistical Review of World Energy via The New York Times)

Energy Transition: Challenges

One key to harnessing that wind lies at the end of a causeway jutting into the bay, on a mostly undeveloped island where eagles fish offshore and people walk in the quiet shade. Many officials see this spot, known as Sears Island, as the ideal site to build and launch a flotilla of turbines that could significantly lessen Maine’s reliance on fossil fuels.

Standing in their way are environmental groups and local residents, all of whom are committed to a clean energy future and worried about the rapid warming of the earth. Still, they want the state to pick a different site for its so-called wind port, citing the tranquility of Sears Island and its popularity and accessibility as a recreation destination.

On a recent summer morning one conservationist against the plan, Scott Dickerson, sat on a picnic bench and predicted environmental groups would sue to thwart development of the island, as they had many times in the past.

“And that, as you can imagine, is going to run the clock,” he said, costing the state valuable time that could be saved by looking elsewhere.

The NIMBY (not in my backyard) mentality has never left us and it is completely bipartisan (See my August 27, 2012 blog).

Energy Transition: Politics

In conversations with activists, policymakers, and corporate executives, it becomes clear that a save-the-planet argument doesn’t go very far. Most people won’t buy green technology unless it will clearly save them money and wows them with stunning designs or jaw-dropping performance.

Many, conservatives in particular, chafe at the prospect of the government forcing them to buy electric cars or ditch their natural gas appliances, polls show. That’s perhaps why those pitching the technology often avoid mentioning climate change. They emulate evangelists who don’t lead with Jesus when trying to win over nonbelievers.

The Inflation Reduction Act passed by Democrats last year allocated hundreds of billions of dollars in incentives for wind and solar manufacturing, electric vehicles, and other clean energy.

Although no Republicans voted for the bill, much of the money has gone to G.O.P.-led states in the South where many automakers, battery manufacturers and solar companies are building factories in part to take advantage of the law’s tax breaks.

Getting credit for the new jobs is a political imperative for President Biden, who will be seeking re-election next year. That helps explain why his energy secretary, Jennifer Granholm, spent part of July traversing the Southeast in a caravan of electric vehicles.

Among residents benefiting from the economic boost, attitudes may be softening. Outside Dalton, Ga., Qcells, a maker of solar panels, is planning to expand a manufacturing plant. The factory is in the congressional district represented by Marjorie Taylor Greene, a Republican who has called fossil fuels “amazing” and climate change a “scam.”

William Turner, 49, one of Ms. Greene’s constituents, said he didn’t “really buy into that stuff” about global warming. But he added, “I don’t have anything against solar, especially if it’s creating jobs.”

My wife didn’t start with the digital version but waited for the printed version. I doubted that she would read all three articles but was curious to find out if she would read any and if so, which one she would choose. Well, the answer was simple – the series didn’t show up on the printed version. I thought, well, maybe the mysterious “August 16” written after the introduction could mean that the printed version would include the articles on the 16th. It didn’t. Aside from the August 12th digital version, I have yet to see it anywhere.*

A sort of “revisit” of the energy transition series showed up in the August 18th printed edition of the NYT in the “The Story Behind the Story” section written by David Gelles.

*I generally write these posts ahead of time. After writing about the missing articles above, they finally appeared as a full supplement in the printed version that showed up this past Saturday. My wife and I were able to see it only on Sunday because we were traveling away from home. I mention to my wife what I had written in the blog and asked her the same questions I had planned on asking her originally. Her response was that she “scanned” all three.

This gave me another idea about how to quantify “cherry-picking” of a larger, more complex, reality: every weekend the NYT comes out with a quiz. Both my wife and I usually try to solve the multiple-choice quizzes. If we are doing well, we brag; if we are not doing so well, we keep quiet. They generally cover a few explanatory articles. It will be interesting to take such a quiz on a single complex issue with political implications. From this exercise, I will try to quantify the informational cherry-picking and thus contribute to our understanding of polarized attitudes that public information can address.

Bringing My Family Tree to Australia

The details of our trip to Darwin were outlined in the first blog that I wrote and posted three days after our return (July 25th). I wrote that “the main driving force that led us to take the trip was the family trip to Melbourne.”

My Australian family started with my cousin (his father and mine were brothers), who is eight years older than me, also born in Warsaw, Poland. In that blog I also included a reference to a recent interview that he gave about his life in Warsaw during the war. In the meantime, I have found an older reference that includes a short summary of the life that he had built in Australia.

I came to Australia with the knowledge that during our stay in Melbourne, we would encounter social occasions where we’d be invited to settings that would include family members that have no idea about the relationship of my family with my cousin’s family. So, I decided to bring my family tree with me. The direct descendants of my cousin are familiar with the connection mainly because this was not our first visit to Melbourne and a few of them also visited us in the US. But family trees are open-ended documents that constantly change with time. The changes are “small” when children are born but the changes can be very large with marriages, because full new family trees are incorporated as a result of a single new marriage link. Aside from the people directly involved, chances are that members of the two families know very little about each other. Indeed, my “prediction” was confirmed at a family event that one of my cousin’s daughters arranged that included her direct family, my cousin, my wife and the mother-in-law of my cousin’s daughter. My wife and I had never met the mother-in-law, so I was glad that I had brought my family tree with me to start a lovely conversation.

I also had an ulterior motive for bringing my family tree to Australia and writing about it in this blog.

I mentioned before that my cousin’s early background has important similarities to mine. We were both in Warsaw at the start of the German invasion of Poland that started WWII and the resulting Holocaust. The difference was that at that point he was 8 years old, and I was 3 months old. This fixes my age above the life expectancy of every country in the world. (Japan holds the record – 82). I still teach, write, and travel but I am fully aware of my limited prospects. So, I am always on the lookout for younger relatives who can take over the administration of my family tree. The Holocaust made sure that, together with the more normal dynamics of family trees such as marriages and births, my tree turns out to be global. The Australian branch is an important offshoot of this tree. In addition to Australia, my tree has major branches in France, US, and Israel. I felt (and still feel) that an important part of my job is to try to ensure continuation of the data-gathering beyond my life span. I feel that with electronic communications in our possession, the dream that all humanity will be part of the same tree is not totally outlandish and that it can contribute to a feeling that all of us are parts of the same family and thus responsible for each other.

The current “record keeper” of the biggest family tree is the Oxford University Big Data Institute with 27 million people. This database is based on genomic research that promises to extend history beyond the written record to include genomic records and thus unify our academic definitions of history with archeology, anthropology and other disciplines that deal with our past. Genomic sequencing is fast becoming part of our “reading skills” and life itself is being redefined, in one sense, as a genomic writing ability. My dream is to try to redirect this to fortify our collective chance of survival. I fully realize that this is a dream that most probably will not materialize. This outlook is fed by my observation that my younger generations are fully occupied with their own dreams for their future and that “collective” dreams are not a priority for them.

A sprinkle of exception to this pessimism came from my Australian family.

The youngest son of my Australian cousin likes to travel, both professionally and as a tourist . In one of his trips that followed a trip with his father to Poland to share my cousin’s early past, he “discovered” Wysokie Mazowieckie (WM) and the efforts that some people (local and foreign) are making to resurrect the Jewish cemetery there.

A few years after that “discovery,” my wife and I took a trip to WM and met Karol Glebocki, the teacher that, with his students, became central to this effort. Figure 1 shows both of us with the tombstone of Aaron Avigdor Tomkiewicz (AAT), a man who already was the oldest ancestor in my family tree.

Figure 1 – Karol Glebocki and me near the gravestone of Aaron Avigdor Tomkiewicz in the newly restored Jewish cemetery in Wysokie Mazowieckie.

I didn’t start my family tree with the visit to WM. I started it a few years earlier, driven by a similar motive that drives me now in my search to move the effort to a younger generation. My uncle (younger brother of my mother) was with us through our Holocaust experiences but decided to settle in France and start his own “branch” there. At the time, he was the guy that was left with the most detailed memory of our past. I decided to construct the tree based on input from him. My objective was not to find my origin but just to be able to connect as many surviving members of my family as possible. For many years, to my knowledge, I was the only one in my family to administer the data. Two questions remained unanswered. AAT was listed with two wives. I was sure that he was not a bigamist, but I had no idea about the details. I knew of a French family that hosted me during the Israeli Independence war, but I knew nothing about the details of the links. Both questions got answered when I was able to link with David Askienazy from Paris. He is much younger than me and much more active and productive in assembling his family tree (listed in “My Heritage”). After our contact, my family tree grew considerably. The last major development went back to WM and a connection with Aaron Rotenberg, through the Jewish Record Indexing – Poland, with detailed data search in WM. I haven’t yet analyzed all the new data that he supplied me. My present family tree contains 352 members!

The “normal” dynamics of a family tree can be demonstrated with very recent developments that took place this year:

Over three months ago, a first granddaughter was born to my French cousin. We had the opportunity to enjoy the three generations on Zoom.

Natalie Leventhal,the grandmother of my wife’s two nieces, will celebrate her 100 birthday. I will bring the family tree with me to Connecticut, where she lives, so the younger generation will be able to take over administration of that branch.

Toward the end of this month, my wife and I will travel to Washington, DC to attend a Holocaust meeting and stay with my American cousin. We will bring the family tree with us.

The “ultimate” impact on my family tree took place few days after our return from Australia. I got an email from Matt Rozell (see below) saying that he found, in the US archive, a short movie clip taken by American soldiers that unquestionably describes our liberation by the American army on April 13, 1945 near the German town of Farsleben.

You can watch the clip-on YouTube.

After 78 years, this was a sensational find. Social networks were full of feedback and all the Israeli papers that I have access to, both in English and Hebrew, mentioned it. I got emails both from Israel and the US asking me if this was “my” train. It was. The Jerusalem Post, an Israeli, English language paper, probably had the fullest history of the event.

A short description taken from the article is below:

Never-before-seen footage of Holocaust survivors being liberated by US Army soldiers during the last stretch of World War II has been unearthed at the United States National Archives, according to a Wednesday report by the Independent.

On Friday, April 13th, 1945, soldiers from Tanks 12 and 13 from the US Army’s 743rd Tank Battalion led by a scouting jeep liberated a train transport with thousands of Holocaust victims who had left the Bergen-Belsen concentration camp one week before and were bound for Theresienstadt.

First, I started to do what many survivors of this event do – try to find myself or my family there. (My mother and her younger brother were also there.) A 78-year gap is no help. So, I tried to do better. I went through my mother’s small Bergen-Belsen book, whose title, translated into English, reads, “There was Life Even There” (it is shown in Figure 2), to look for a description of the event as written shortly after our liberation. Here’s her description of the liberation as written close to the end of the book:

On the 13th of April we stop next to a copse. The trees are humming, the birds are twittering, a light breeze wrinkles the surface of the river. Someone says we’re not far from Magdeburg. Pilsudski was imprisoned in Magdeburg, wasn’t he? They’re shooting at us from the planes. The Germans are shooting at us from the copse. I can’t see much from under my pillow. Mulek went on reconnaissance. When he came back he said they’d fished our Auslander documents out of the river. It turns out that our Palestinian certificates had arrived from Switzerland in February. That Kastner chap didn’t forget afterall! Why did the Germans throw the documents into the water? What will happen to us?

There are corpses lying on both sides of the train. The engine driver has made off on the locomotive. So we’re on a train with no locomotive and a German crew who beat us, spit at us and curse us in the intervals between shooting. They have an order to finish us off and throw our bodies into the Elbe, just like they’ve done with tens of thousands of concentration camp victims in the last few months. Is it now? Maybe they’ll wait another hour or two.

A handful of human spectres made it from the train to a town nearby and begged some food from the Germans. “They were completely normal, like they weren’t Germans at all,” says someone with surprise. Stas and Hela went too and got a chicken and a few potatoes in return for my broken gold watch. What luck! Renia cleans the chicken and cooks it on a Primus borrowed from the Czechs. Slawcia advises us to add what’s left of the dried potatoes. There’ll be more that way. The whole compartment participates in the feast without paying any attention to the shots and ceaseless cannonade whose threatening sounds are coming from afar, from near, no matter where from. We eat. Will they make it in time? Won’t they? “How did you get hold of so many potatoes?”

Suddenly the first American soldier appears. How inconspicuous he is! Behind him there’s a group of others. One of our wheeler dealers has already recognized the friend of a friend in America. The American soldier waves his hand. His trousers are creased. We’re free.

We’re saved. Stas throws himself to the ground and cries. Others are crying, laughing, kissing. I don’t feel like crying. I feel stupid, totally empty inside. So this is the way the war has finished for us? Without pathos. Without drama. An American soldier with creased trousers and now it’s the end after so many years. So many ages.

Magdeburg is taken and the 9th American Army has taken us into its possession. Bobus proudly brings me a rucksack containing a dirty towel and a jagged comb. The children kick the Germans, take their guns away, their bikes and rucksacks.

The adults are too weak to take revenge. They don’t feel triumphant. In fact they don’t feel anything. They throw a guard to the ground. “Kneel,” they shout. They torment him, but without conviction, as if it were a duty, mildly. They’re still completely bewildered. They don’t know what to do with him, with themselves. But yesterday this selfsame guard was hitting women in the face when they begged him for a few rusks. Except what will it achieve? The Americans offer cigarettes, hand out bars of chocolate. “Aren’t you happy?” they ask. Are we happy? We don’t dare ask ourselves that question. Mother, father, Piotr, Witek, Helenka … We’ve survived and what now? “Won’t we need these potatoes anymore?” we ask the Americans uneasily.

The girls are flirting with the soldiers. Singing. Conversations. The Americans photograph the specter-train from all sides, and us, the specters from the train. We must light a fire and boil a few potatoes. I must wash Bobus and put him to sleep. Mrs M. shrieks at the top of her voice. Her husband has just died this minute. He was already a free man. She’s left with four children just when the war has finished. A huge blonde in an American uniform brings a bottle of wine to the compartment. Do I want some silk stockings? Would I go for a walk with him? He fought for me after all. He fought. I’m as light and empty as a soap bubble. My head’s spinning from the wine. From the freedom which has arrived too late for happiness. “My little one didn’t live to see the day,” says Sonia and cries. For joy?

Next day we leave the train. They take us to beautiful Hillersleben, they’ve previously thrown the Germans out. We become “Displaced Persons of the World.”

Figure 2

You have here what you need to compare my mother’s description of our liberation with that of some of the liberators. Not surprisingly, they are not the same. They are two different perspectives. To my knowledge, this is one of the few opportunities that exists to read these views. For that, I thank Matt Rozell and my mother.

The first of my blogs that describe Matt Rozell’s continuous efforts to get the liberators and survivors together was written two months after I started this blog (June 4, 2012). An important follow up came when, jointly with the people of Farlsleben, a monument was erected there that was shown in the April 12, 2022 blog. A photograph of Matt Rozell that commemorates the D-Day anniversary is shown in the June 11, 2019 blog (the guy on my left without glasses).

It is obvious (at least to me) that without this event “my” family tree wouldn’t even exist.

Traveling to the Weather: Darwin

Figure 1
NT State Population (Source: https://images.app.goo.gl/mVia9Q8aQhxrdgsF8)

The details of our trip to Darwin were outlined in the first blog that I wrote in this series, that was posted three days after our return (July 25) and I’ll focus this blog on our Darwin trip and its environs. About 5 days were spent in an organized tour in the National Parks around Darwin, a map of which was included in that blog. They include Kakadu National Park, Litchfield National Park, and the Katherine Gorges.

Figures 1 and 2 provide a general picture. Darwin is the capital of the Northern Territory (NT). It is not a State because even the population of tiny Tasmania (that is a state) exceeds it by a factor of 2. Half of the population of NT is around Darwin; even with that, Darwin counts as a small city. Figure 2 indicates that at least in the dry season (see last week’s blog), the city and the parks around it are significant tourist draws. Indeed, walking around the city leaves the impression of a crowded place. Most of this blog will focus on a few photographs that we took during the visit.

Figure 2

Before shifting to the photographs, here are a few words (and sites) about the weather and about Kakadu National Park:

The Weather (Source: https://www.australia.com/en-us/facts-and-planning/weather-in-australia/darwin-weather.html):

The wet season (November – April)
The wet season in Darwin is characterized by high humidity, monsoonal rains and storms. Average temperatures range from 24.7 – 32 °C (76.5 – 89.6°F), and humidity can push past 80 per cent. The average annual rainfall is 1727.3 mm (68 inches) and January is the wettest month. Despite this, January and February is considered by many as the most beautiful time of year in the Top End. Sunny days and afternoon storms refresh the landscape, and animals and plants flourish.

October to December is the season of spectacular lightning storms, an event eagerly awaited by locals who watch the show from beachside restaurants and bars.

The dry season (May – October)
The dry season, from May until October, is characterized by warm, dry sunny days and cool nights. Temperatures typically range from 21.6– 31.8°C (70.9 – 89.2°F), and humidity levels are much lower: around 60 – 65 per cent.

Relatively cool weather arrives in May, and until July, nights are crisp with temperatures ranging from 17 – 23 °C (62.6 – 73.4°F). It is also the perfect time to explore the more remote areas of the region that can be off-limits during the wet season.

For contrast, the average annual precipitation in NYC is 46.6 inches (1184 mm).

Kakadu National Park                                                                                                        (Source:  https://en.wikipedia.org/wiki/Kakadu_National_Park)

Kakadu National Park is located within the Alligator Rivers Region of the Northern Territory, covering an area of 19,804 km2 (7,646 sq mi), extending nearly 200 kilometers (124 mi) from north to south and over 100 kilometers (62 mi) from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second-largest national park in Australia, after the Munga-Thirri–Simpson Desert National Park. Most of the region is owned by the Aboriginal traditional owners, who have occupied the land for around 60,000 years and, today, manage the park jointly with Parks Australia. It is highly ecologically and biologically diverse; hosting a wide range of habitats and flora and fauna, Kakadu is fully protected by the EPBC Act. It also includes a rich heritage of Aboriginal rock art, including highly significant sites, such as Ubirr.

All our friends on the tour of the national parks were Australian. We asked the guide if this is the norm. She responded that on the previous tour, there were a few Americans and Canadians. All of us were “traveling to the weather.”  But all of us were aware that these are luxury travels that very few can afford. There is another kind of “weather traveler,” one for people that have no other option. We labeled these as “environmental refugees” and I’ve often written about this topic. (see April 3, 2018, e.g.). Most of us cannot escape the impacts of climate change. Recently, President Biden took some steps that include protections for construction workers, farmers and other laborers who are exposed to sweltering heat. All of us realize that much more needs to be done.

What follows are some pictorial highlights of the trip:

Figure 3

These mounds can last 50-60 years.

Figure 4
Kakadu National Park from above

The main conclusion that I draw from the landscape of Kakadu, is the power of water, with almost no human help or destruction, to enrich the landscape. We were given a warning about the river network: don’t swim in these rivers. The reason is shown in figure 5.

We departed from Darwin with a gorgeous sunset as shown in figure 8.

Sunset in Darwin

One of the best opportunities to see the sunset is to walk on one of the beaches in the late afternoon where, twice a week, during the dry season, a sunset market takes place that invites all the attendees to watch the sunset (figure 9) after buying all kinds of stuff.

Traveling to the Weather

Last week’s blog outlined the reasons why my wife and I decided to take our vacation in Australia. The main reason was to see family in Melbourne and a secondary reason was to try to have a short break from the weather back home. I promise that in this and in following blogs, I will go into some details.

Traveling to visit family is a common activity that many of us do whenever we have the opportunity. I think that documenting changing extended families has the long-term outcome of developing a feeling that all of us belong to the same family and thus willing to take care of each other.

For now, however, this blog will focus on the weather.

Discussing the weather requires some background. Weather and climate are the most important topics of this collection of blogs. However, I never discussed the fundamentals of the driving forces of climate in a way that would  be understandable with no educational prerequisites. I will try to remedy that here with some quoted literature.

I think the best starting point  is the short review by Stevens in Nature Education that references figure 1 and from which I extensively cite below. This review will serve us in this and next week’s blogs. It  describes the background for choosing Darwin as an important component of our Australian vacation and it will also serve as a background for future blogs that will describe the roles that El Niño and La Niña are playing in our present climate.

 

Sunlight Intensity Is a Key Component of Climate

Directly or indirectly, the sun provides energy for living organisms, and it drives our planet’s weather and climate patterns. Because Earth is spherical, energy from the sun does not reach all areas with equal strength. Areas that are exposed more directly to the sun’s rays (i.e., those nearest to the Equator) receive greater solar input. In contrast, those in higher latitudes receive sunlight that is spread over a larger area and that has taken a longer path through the atmosphere. As a result, these higher latitudes receive less solar energy (Figure 1).

The sunlight intensity on some parts of the earth significantly varies over the course of the year as the earth changes its orientation in space. Seasonal variation in solar input occurs because the Earth is tilted on its axis by 23.5˚ (Figure 1). As Earth orbits the sun, its orientation to the sun changes. Winter in the northern hemisphere occurs as the northern tip of the planet tilts away from the sun; during this time, the southern hemisphere receives greater solar input and experiences summer. As Earth reaches the opposing point of its orbit and the northern hemisphere becomes angled toward the sun, the seasons reverse. Tropical areas experience relatively minor changes in temperature, and their seasons are characterized by the presence or absence of rain.

Sunlight Intensity Affects Global Winds, Precipitation Patterns, and Ocean Circulation Which Are All Components of Climate

At the Equator, the Earth receives greater exposure to the sun’s rays where both air and extensive bodies of water warm under the influence of the sun. Molecules are more closely packed together when cold than they are when warm, which makes warm air and water less dense than cold air and water. This difference in relative density causes heat to rise.

The warm air that rises in the tropics is wet. Sunlight causes water to evaporate from plants, soils, and bodies of water. These water molecules rise to become part of the air; because the air is warm and less dense, there is sufficient room for water molecules within the air mass. But as the air gains altitude it cools, reducing density and space for water. The water molecules condense to form clouds and eventually fall as precipitation. At the same time as sunlight is driving evaporation and precipitation patterns, it is also creating winds. As warm air moves upward, colder air from neighboring areas rush in to fill the void left behind. Tropical air moves away from the equator and toward the poles. As it travels, it cools, becomes denser, and eventually descends around 30˚ north or south latitude. This dry air mass, having lost its moisture in the tropics, absorbs moisture from the ground, creating arid conditions at these latitudes. Some of the air is drawn back toward the equator, and some is drawn toward the pole as part of a new air mass. At latitudes around 60° north and south, the air again rises, cools and releases precipitation (though less than in the tropics). Some of the cold, dry rising air then flows to the poles, where it absorbs moisture creating the cold climates of the polar regions.

Winds are also generated by the rotation of the earth. Unlike the northern and southern direction of the winds described above, there are westward and eastward winds. These winds affect ocean currents. Warm, tropical waters carry heat pole-ward along the east coast of continents; cold water from the poles is forced toward the equator along the west coast. Warm surface currents can carry heat well away from the tropics, bringing temperate climates to areas nearer the poles than the Equator. Deeper currents are driven by a combination of Earth’s rotation and temperature differences between the tropics and the poles. Cold, dense melted water from the icecaps flows underneath warmer surface waters towards the Equator. The combination of wind and ocean currents redistributes heat and moisture across Earth’s surface. Around 60% of the solar energy that reaches the earth is redistributed around the planet by atmospheric circulation and around 40% by ocean currents.

Out of this interplay between our spherical orbiting planet, sun and oceans, global regions rise that divide the year into dry and wet periods.

For so many of us in the developed world, the seasons are defined by temperature. The freshness of spring, the heat of summer, the chill of autumn and the cold of winter. But for the billions of people on our planet that live in the tropics, the seasons are marked by the presence, and absence, of rain. The annual coming of the rains after months of drought, with the renewal of life from the giving water… And then, after months of rain and clouds, the sun reborn into blue skies as the next dry season begins. This is the domain of the tropical wet and dry climates. This is the Tropical Monsoon and the Tropical Savannah.

The global extent of the tropical Monsoon-Savannah wet and dry regions are shown in figure 2 with a short description below:

Figure 2
Tropical Wet and Dry Climate (Source: climatetypesforkids.com)

Tropical Wet and Dry climate is mainly found within the tropics. The tropics are two lines of latitude about 23.5 degrees north and 23.5 degrees south of the Equator. Land in this area receives direct sunlight throughout most of the year. Tropical Wet and Dry is known for its two seasons.

This band is further explained in the NOAA entry.

The Inter-Tropical Convergence Zone (ITCZ) appears as a band of clouds consisting of showers and occasional thunderstorms that encircles the globe near the equator. The solid band of clouds may extend for many hundreds of miles and is sometimes broken into smaller line segments. Its existence is due to the convergence of the trade winds: winds in the tropics that move predominantly from the east and curve towards the Equator. When the northeast trade winds from the Northern Hemisphere and the southeast winds from the Southern Hemisphere come together, it forces the air up into the atmosphere, forming the ITCZ.

The geographic extent of the ITCZ in Australia (see the previous NOAA citation) is seen in figure 2. The timing of the dry phase (Feb-March –> August-Sep) coincided with our visit. The temperature of this climate band is approximately constant (70 – 87 F (21-30C)) and the dry weather seemed to be the ideal reprieve for tourists coming from the Northern hemisphere.

Mediterranean Climate (Source: http://www.grabovrat.com/mapsViews/mapsViewsMB00.html)

Mediterranean climate is very pleasant climate with warm, dry summers and cool, mild winters. It gets its name from the Mediterranean Sea. Most of the coastal land around the Mediterranean Sea experience this climate. This climate’s most important cause is the large bodies of water near the land around the Mediterranean and is only found along the coast.

I have some experience living with different kinds of wet/dry climate in different locations. It is known as the Mediterranean Climate. The geographic extent and short explanation of that band is shown in Figure 3. As was mentioned in earlier blogs, I grew up in Israel which is part of that climate band and did part of my early academic career at the University of California Berkeley, in the San Francisco Bay area. I remember fondly my Berkeley years (early 1970s.) and the climate there. Many were surprised that there were no conventional seasons there (at least as temperature was concerned). Often, they didn’t like it because they grew up with seasons. The remedy was that they could travel to “extreme” seasons – to mountains looking for “real” winter (snow) and to deserts for “real” summer (cactus trees and sand in the south).

However, recent changes in parts of the region that were covered by the Mediterranean Climate that historically were considered the “Cradle of Civilization” and “Birth of the Agricultural Revolution,” are now going through desertification almost unfit for human habitation. I will follow these developments in future blogs.

The next blog will expand (with some pictures) on finding the weather (and more) in Darwin. I will show that Darwin, in terms of weather, is the “Garden of Eden” for tourists in the dry season. It is something else in its wet season.

The Conflicting Reasons for my Australian Vacation

Figure 1 – Map of Australia (Source: Geology.com)

Figure 2 – The three national parks around Darwin

My wife and I are back from a three-week vacation in Australia. In this blog, I will try to explain why we went there in the first place and why my next series of blogs will be dedicated to this trip. The trip was structured so we spent half of the time with family in Melbourne and the other half of the time in Darwin and the surrounding national parks. As strange as it sounds, both halves connected to the rapid changes that now afflict our planet, and to which this blog is dedicated. However, the connection to climate change of such a trip is unquestionably problematic: the flying distance from New York City, where we live, to Melbourne is 16,763 km (10,418 miles). In addition, the distance between Melbourne and Darwin is 3,740 km. There is no question that flying such distances is not good for the planet. To add to that, both my wife and I are of an advanced age (I am of a considerably more advanced age than my wife) and our health is fragile. Flying such distances in economy class is brutal for our bodies. Fortunately, we could afford to fly business class. By doing so, however, we doubled the environmental impact of our flights.

The main driving force that led us to take the trip was the family trip to Melbourne. My family there started with my cousin (his father and mine were brothers), who is eight years older than me, also born in Warsaw, Poland. Unlike me, he encountered the Nazi invasion at the age of 8 (I was 3 months old when the Nazis invaded Poland). He survived the Holocaust and after a few years in Israel, he ended up in Melbourne with his stepfather and his mother. A few months ago, he was interviewed in Australia about his early experiences. Recently, he lost his wife, and we felt a strong urge to spend some time with him and his family. I will dedicate a future blog to making a case for constructing massive societal family trees until we demonstrate that all of us are members of the same family and thus share responsibility for each other’s well-being.

Summer break usually gives faculty time to “rearm” themselves with developments in their fields. The trip to Darwin—and to the surrounding national parks shown in Figure 2—was designed to accomplish that while also catering to our interest in exploring unfamiliar parts of the world.

July is mid-winter in Melbourne. During our stay, we had one rainy day. It was very pleasant to walk around, but less pleasant to swim. We went to Darwin to experience something different. As can be seen in the opening map, Darwin is at the northern tip of the continent. There is no winter or summer there per se, but there is a dry and a wet season. We were there at the height of the dry season, with temperatures that we might associate with a mild summer (around 25oC or 77oF). Darwin is the capital of the Northern Territory of Australia, with relatively few residents (but a lot of tourists).

The last two blogs, one by me and the other by Sonya Landau, focused on the water stress in Arizona and its conflicts with population growth. Water stress is one of the most important impacts of climate change on Arizona and many other parts of the world. Adaptation to the dry season is one of the most important tools to adapt to climate change. The visit to Darwin taught me how nature can create wonders in the wet season and how the landscape can adapt to water stress during the dry season. The next blog will try to explore these trends further.

We had some surprises in Australia that have nothing to do with environmental impact and thus will not be expanded to separate blogs. The biggest surprise (at least to me) was the news that I really didn’t need to bother exchanging my American dollars for Australian ones. We were told that—at least in the places that we planned to visit—nobody uses cash. We didn’t believe our sources and got some Australian dollars anyway. It turned out our sources were right. In Melbourne, the only place that required cash was a small Chinese restaurant where we had lunch. In Darwin, at the entrance to the Hilton hotel where we stayed, there was a sign, shown in Figure 3.

Photo of blue and white sign that says "This hotel is cashless, no money on site"Figure 3 – The “warning” on Darwin’s Hilton door

We didn’t bother to inquire what was behind the story that made management post the sign. When we went out, the soft drink machines (shown in Figure 4) made the overall shift to a “cashless” economy clear.

Photo of two soft drink vending machines. Both say "100% cashless" at the top.Figure 4 – Soft drink machines in Darwin.

Before leaving Australia, we had to change almost all our Australian money back to American dollars. I didn’t use the trip to start the conversation about the impact of such a shift on people who cannot open bank accounts and get credit cards, however, I have no doubt that such a conversation will start if the trend expands beyond the Australian borders.
