Extreme weather accounted for 9.4% of all deaths globally between 2000 and 2019, according to researchers who on Wednesday published the first study linking changes in temperatures to annual increases in mortality. While most deaths have been caused by exposure to the cold, the trend is likely to reverse as the planet warms.
The last two decades were the hottest since the pre-industrial era with the 10 warmest years on record occurring during the period. Global warming continues to accelerate, with the planet on track to warming around 3 degrees Celsius above the pre-industrial average, according to estimates by nonprofit Climate Action Tracker. Scientists forecast that a warming of more than 2°C would be catastrophic for life on Earth.
