The Brief on "Arctic warming amplifies climate change and its impacts" now has almost 200 pieces of evidence uploaded, showing broad consensus on this topic.
Where as there is a clear consensus for the existence and impacts of Arctic amplification, debate surrounding links to mid-latitude extreme weather lowers the score.

Warming in the Arctic has occurred at above double the global average, something known as Arctic amplification. This combined with more frequent Arctic heatwaves during the 21st century has reduced sea-ice coverage.
A range of impacts have been observed in the Arctic, including permafrost thaw and wildfires. The record temperatures in Siberia in 2019 and 2020 and in western North America in 2021, or the 2021 Texas cold snap, could be examples of the changing Arctic climate.
While many papers have drawn links between the recent decline of Arctic sea-ice extent and increased mid-latitude extreme weather there is debate surrounding the strength of possible causes. Different hypotheses and contrasting results from observations and modelling studies mean further research and analysis is required.
The Arctic is a critical frontier for the study of climate change science. To read the ScienceBrief Review on the Arctic warming click here.
