The Associated Press (AP) has produced an interactive feature that explores increasing heat extremes in cities worldwide. The feature uses data from CIESIN, a center within the new Columbia Climate School. The dataset was produced as part of a study led by CIESIN postdoctoral research scientist Cascade Tuholske, published last month. Tuholske and his co-authors combined temperature and humidity measures with population estimates to better understand how growing heat extremes impact vulnerable urban people. They found that global urban extreme heat exposure has tripled since the 1980s, raising concerns about the health and well being of billions of people worldwide.

The AP feature guides you through the data set and visualizes the threat of the intersection of rising temperatures and soaring population growth. Go to the AP site to tour the world’s hottest cities, and learn how increases in extreme heat are likely to impact growing numbers of people around the world in the coming decades.
