Antarctica

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.

Where there was a white ice cap, there are now brown blotches of land; melted snow and ice have created ponds of water. Those are the effects of the recent record high temperatures in Antarctica, according to NASA, which on Friday released stunning before-and-after satellite images of the northern Antarctic Peninsula.

Antarctica experienced its hottest day on record Thursday.

At least, that's what scientists reported at Argentina's Esperanza research station, on the very northern tip of the Antarctic Peninsula. The finding, announced Thursday by Argentina's national meteorological service, placed the temperature at 18.3 degrees Celsius — or just about 65 degrees Fahrenheit.
