From 1979-2018 East Antarctica cooled -Zero.70°C/decade (-2.eight°C), West Antarctica cooled -Zero.42°C/decade (-1.68°C), however the Antarctic Peninsula warmed Zero.18°C/decade (Zero.72°C). Thus, as an entire, the Antarctic continent has cooled via about -1.five°C to -2°C all over the similar length CO2 rose from 337 to 410 ppm.

Zhu et al., 2021

“The temperature development from ERA5 is in line with that from observations, wherein a cooling development dominates East Antarctica and West Antarctica, whilst a warming development exists within the Antarctic Peninsula except for all over austral summer time.”
“The tendencies in ERA reanalyses and observations are all unfavourable in East Antarctica in all annual and seasons, and the quickest cooling development seems in MAM, and the cooling price of this season is greater than 1 °C consistent with decade. In West Antarctica, the ERA5 tendencies are very similar to commentary tendencies, while there’s a distinction between ERA5 tendencies and ERA-Intervening time in SON, as mirrored in a warming development in ERA-Intervening time whilst a cooling development is noticed in ERA5. ERA5 reveals an important cooling development in annual information, MAM, and JJA, and the tendencies from ERA-Intervening time all the time fail to move the importance take a look at.”
“It is usually value bringing up that the ERA5 presentations a quicker cooling price than ERA-Intervening time and observations in West Antarctica. Over the Antarctic Peninsula, tendencies of annual and seasonal temperature manner in ERA reanalyses and observations don’t seem to be vital. ERA5 items a warming development except for DJF, as is the case for ERA-Intervening time and station information.”
