“Polar amplification” usually refers to greater climate change near the pole compared to the rest of the hemisphere or globe in response to a change in global climate forcing, such as the concentration of greenhouse gases (GHGs)…RealClimate [emphasis added]

It’s fall. The Arctic is trying to cool down, but what would typically be a steady decline into frigid temperatures is being held back by the increasingly strong hand of human-forced climate change.

(Over recent weeks, temperature departures above the 1958-to-2002 average line [green line above] have grown in the region north of the 80th parallel. In general, the Arctic has experienced much warmer than normal temperatures. Failure of the Arctic to rapidly cool down during fall has been a feature of recent years that is related to human-forced climate change. Image source: DMI.)

Over the past month, temperature anomalies for the entire Arctic have ranged…
