Every year, Bulletin of the American Meteorological Society publishes a summary of the climate and they dedicated one chapter to the Arctic. Global warming due to human-caused climate change is dramatically changing the Arctic, enhanced by physical processes that cause the Arctic to warm more quickly than the global average, referred to as Arctic amplification. Most importantly over the past 40+ years, the Arctic has also become wetter, with seasonal shifts and widespread disturbances influencing the flora, fauna, physical systems, and peoples of the Arctic. AER Principal Scientist Judah Cohen contributed to the chapter focusing on extremes in the Arctic. Specifically, Cohen discusses how these profound changes in the Arctic can influence weather and even extremes outside of the Arctic.
Figure 1. The historical temperature ranking (T2m) of the 2022 mean air temperature compared to the 1950–2022 period. Note how many regions experienced air temperature rankings among the five highest temperatures on record, with extremely warm regions in the Barents Sea, central Greenland, and parts of Siberia.
