Considering the previous post, this seems timely.
Temperatures in southern Ontario approached ten degrees celsius again today. Canadians can get a little goofy when things like this happen, and we actually saw a few kids out in shirtsleeves when we went for a afternoon stroll. While we are tempted to think that this might be a result of global warming, it's really just a freaky winter as a result of the polar vortex spending all of its time in Russia. It seems that this brings them something approaching unprecedented cold and us an unusually mild winter as these excerpts from this article in The Globe and Mail point out.
Laymen may be tempted to attribute the phenomenon to global warming, but if climate change was as rapid as all that, Canadians would be planting citrus groves in five years and living in deserts within a few generations. "This may be a dry run, a dress rehearsal, of what winters might be like in the future," Mr. Phillips said. "But we can't say that this is the beginning of the permanent change."
... the climatologist blames "a total absence of cold air" for the relative warmth. His explanation may seem a no-brainer, but the details are elaborate.
... Usually, the vortex lingers somewhere for a while and then moves around of its own accord, its shifts causing other fluctuations of warm and cold air masses. Yet this year, "day after day, week after week, month after month now, this cold pole is just not coming over to this part of the world," Mr. Phillips said.
The vortex's failure to move has allowed warmer air to come into Canada -- and stay.
Meanwhile, here's sundown through our bedroom window on this fine day.
