Simulations Confirm Observations of 2015 India/Pakistan Heat Waves

December 15, 2016

A paper published December 15 during the American Geophysical Union (AGU) fall meeting in San Francisco points to new evidence of human influence on extreme weather events. Three researchers from Berkeley Lab are among the co-authors on the paper, "The Deadly Combination of Heat and Humidity in India and Pakistan in Summer 2015," which examined observational and simulated temperature and heat indexes and concluded that the two separate heat waves "were exacerbated by anthropogenic climate change."
