New paper finds Arctic sea ice strongly linked to varying storm activity

Warmists often claim changes in Arctic sea ice are a consequence of allegedly-anthropogenic global warming. However, a paper published today in the Journal of Geophysical Research finds that "dramatic interannual changes" in Arctic sea ice extent are due to varying storm activity in the months of May-July, which impacts "cloud cover and ice motion, and consequently sea ice melt." The authors find fewer cyclones in the Arctic Ocean "appear to favor a low sea ice area at the end of the melt season." Thus, the alleged connection between AGW and Arctic sea ice extent becomes all the more elusive.
