With just a few weeks left, 2020 is in a dead-heat tie for the hottest year on record. But whether it claims the top spot misses the point, climate scientists say. There is no shortage of disquieting statistics about what is happening to the Earth. The hottest decade on record is coming to a close, with the last five years being the hottest since 1880. 2020 is just two-hundredths of a degree cooler than 2016, the hottest year ever recorded.
