"Unprecedented Overlap: Climate Change's Impact on Extreme Heat and Droughts in North America"
A new study published in Science Advances reveals that hotter temperatures are exacerbating the megadrought in the Western U.S., leading to the emergence of "hot droughts" – dry conditions intensified by heat. By analyzing tree rings, researchers found that the last 20 years have seen unprecedented frequency of compound warm and dry summers, attributed to human-caused climate change. The study suggests that future droughts will be worsened by higher temperatures, particularly in regions like the Great Plains and the Colorado River Basin, impacting water reserves for millions of people.
