I answered to this question some time ago:
The user asked if Russia would benefit from climate change.
I found a paper that asserts:
Our simulations with the ECHAM5 general circulation model demonstrate that lower‐troposphere heating over the B‐K seas in the Eastern Arctic caused by the sea ice reduction may result in strong anticyclonic anomaly over the Polar Ocean and anomalous easterly advection over northern continents. This causes a continental‐scale winter cooling reaching −1.5°C, with more than 3 times increased probability of cold winter extremes over large areas including Europe. Our results imply that several recent severe winters do not conflict the global warming picture but rather supplement it.
Source: A link between reduced Barents‐Kara sea ice and cold winter extremes over northern continents", Climate and Dynamics, cited in Expect more extreme winters thanks to Global Warming, say scientists, Independent.
The paper only mentions large areas of the Northern Hemisphere including Europe, but the current cold wave in United States makes me wonder if this is something global and also affecting the Southern Hemisphere.
I am sure climate change make the winters shorter, but are those short winters more extreme?
Is this something global or only regional because of the anticyclonic anomaly over the Polar Ocean?
