The Arctic and Antarctica
From the Arctic region we are today choosing anomalously cold Arctic, with above average Hudson Bay and Greenlandic sector of the Arctic Sea Ice extent anomaly.
Anomaly is so strong, that these days, we are at levels of the 3 “coldest” years for last 10 years, while soon we should be the “coldest” (it means, with a stronger above-average anomaly) since 2015.
At the end, a study about Antarctic ice sheet cooling trends.
