The circumpolar vortex has put this season into the record-books. The United States has just gone through its coldest interequinoctial winter (equinox to equinox) in a century. Hat-tip to CFACT, which has just sent me the graph.

The last U.S. winter colder than this one was in 1911/12, before the First World War.

Thank you, America! Most of Britain has had an unusually mild and wet winter, for you have had more than your fair share of the Northern Hemisphere's cold weather this season.

Global warming? What global warming?
