Global warming means colder winters here

I’ve noticed that many people seem to take the severity of recent winters as an indication that global warming might not be happening.

However, meteorology isn’t a simple science, and today I found an article that claims to have found a reason why global warming would lead to colder winters in Europe: “shrinking sea ice in the eastern Arctic has caused some regional warming of lower air levels and could possibly lead to anomalies in atmospheric airstreams, which may trigger an overall cooling of the northern continents. These anomalies could triple the probability of cold winter extremes in Europe and northern Asia”.

This is of course quite separate from the possibility that the Gulf Stream might one day move or slow down, which would give Scotland and Denmark a climate more like Alaska’s.

Update (3/12): Here are two more articles about this topic, one in Danish and one in English.
