As a whole, the Antarctic has cooled by about 2 degrees Celsius in the same 40-year period (1979 to 2018) that carbon dioxide rose from 337 to 410 parts per million – meaning that the world is actually getting colder, not hotter.
A paper published in the journal Atmosphere noted that the trends from ERA5 are consistent with these observations, showing that there is a cooling trend in East and West Antarctica, while a warming trend comes from the Antarctic Peninsula.
