Use of Computer Simulations in Climate Change Mitigation and Adaptation

Figure 2 in last week’s blog demonstrated our most important tool for determining how we identify human contributions to climate change on both a local and global scale. The figure, taken from the NASA site, describes simulated 20th century global … Continue reading

“Natural” or “Anthropogenic”? – Climate Change

Last week’s blog looked at various methods of distinguishing “natural” vs. “artificial” vanilla. I used this as a jumping off point to facilitate answering the much more important question of how we distinguish anthropogenic climate change from “natural” climate change … Continue reading
