Is the Arctic still warming nearly four times faster than the globe? With 66.5°N latitude threshold, the answer is no.
During the period 1979–2021, the Arctic warmed 3.7 times faster than the globe.
For 1982–2024, the ratio has fallen to 3.3.
So it seems that the amplification is slowing down.
May 7, 2025 06:00One "mistake" we did in our 2022 paper was leaving the title as “The Arctic has warmed nearly four times faster than the globe since 1979,” as if that would hold true every year going forward.
Due to 2023-2024 warming spike, the 43-year global trend increased 16% from 2021, which tends to lower AA.
