CO2 is amazing stuff. The extra heat makes the air cold.

Global Warming could cool down temperatures in winter
The overall warming of the earth’s northern half could result in cold
winters. The shrinking of sea-ice in the eastern Arctic causes some regional
heating of the lower levels of air – which may lead to strong anomalies in
atmospheric airstreams, triggering an overall cooling of the northern
continents, a study recently published in the Journal of Geophysical
Research shows. “These anomalies could triple the probability of cold winter
extremes in Europe and northern Asia,” says Vladimir Petoukhov, lead author
of the study and climate scientist at the Potsdam Institute for Climate
Impact Research. “Recent severe winters like last year’s or the one of
2005-06 do not conflict with the global warming picture, but rather
supplement it.”
