“Telltale signs are everywhere —from the unexpected persistence and thickness of pack ice in the
waters around Iceland to the southward migration of a warmth-loving creature like the armadillo from the Midwest.
Since the 1940s the mean global temperature has dropped about 2.7° F. Although that figure is at best f(sic) Columbia University’s Lamont-Doherty Geological Observatory and his wife Helena analyzed satellite weather data for the Northern Hemisphere, they found that the area of the ice and snow cover an estimate, it is supported by other convincing data.
When Climatologist George J. Kuklaohad suddenly increased by 12% in 1971 and the increase has persisted ever since. Areas of Baffin Island in the Canadian Arctic, for example, were once totally free of any snow in summer; now they are covered year round.

Worth noting that Northern Scandinavia, precisely because it’s on the other side of the polar vortex causing the exceptional conditions in North America, is having an exceptionally warm winter, 4 degrees C above average in some regions. I’ve just come back from skiing in arctic Finland, where it was a balmy - 5/10 rather than the -20+ I usually find there at this time of year. Bears are coming out of hibernation too early, and reindeer are starving because the snow has been through a thaw/freeze cycle and has reset so hard that they can’t scrape through it to the lichen on which they depend.
