Even 2C warming means more killer heatwaves - study

PARIS: Climate change will sharply boost the frequency of lethal heatwaves even if humanity caps global warming at two degrees Celsius (3.6 degrees Fahrenheit), the core goal of the Paris Agreement, scientists said Monday.

Fulfilling that 196-nation pledge would, by 2100, still leave nearly half the world's population exposed at least once a year to bouts of heat and humidity that have proven deadly in the past, they reported in the journal Nature Climate Change.
