Temperature-related deaths could rise five-fold by the end of this century in the US

If global temperatures warm 3 degrees Celsius (5.4 degrees Fahrenheit) above pre-industrial averages and cities do not expand their existing cooling infrastructure, the United States can expect five times the number of temperature-related deaths per year, a new study finds. Adapting cities to heat, primarily through greatly expanded access to air conditioning in the northern states, could slow that trend by 28%.
