One of the more obvious risks of climate change is an increased
frequency of extreme heatwaves. Particularly in cities, heatwaves
can be more than sticky and unpleasant—they can be deadly.

The emissions cuts pledged so far in the international Paris
Agreement in 2015—if followed through—would limit global
warming to the neighborhood of 3°C. That won’t prevent an increase
in deaths due to heatwaves, but just how much worse is 3°C than
the international goals of stopping warming at 2°C or event
1.5°C?

To find out, a team led by
Eunice Lo
at the University of Bristol analyzed the
relationship between extreme summer temperatures and deaths for 15
US cities with data: Atlanta, Boston, Chicago, Dallas, Detroit,
Houston, Los Angeles, Miami, New York City, Philadelphia, Phoenix,
San Francisco, Seattle, St. Louis, and Washington DC.
