Lousy Smarch weather…

Winter wonderland? Meet Monday morning ride

While the Midwest received a blizzard Monday, DC got its only real dose of winter weather, after the official arrival of spring.

Perhaps we had a calendar misprint? Or just a fluke snow+sleet storm?

Either way, the larger pattern of weather extremes, instabilities and oddities (hots, colds, hurricanes, super storms, etc.) might indeed be part of that nasty phenomenon called climate change. Scientists say the unseasonal cold this spring on both sides of the North Atlantic is likely the result of the loss of Arctic sea ice. Climatology is complicated, but here’s the gist: The loss of ice cover warms the polar ocean which shifts the jet stream in a manner that allows colder Arctic air to reach mid-range latitudes, precipitating snowfall when we’d expect warmer weather.

The heavy snowfall and freezing temperatures which have marked March 2013 across the northern hemisphere are in stark contrast to March 2012 when many countries experienced their warmest-ever springs. The hypothesis that wind patterns are being changed because melting Arctic sea ice has exposed huge swaths of normally frozen ocean to the atmosphere would explain both the extremes of heat and cold, say the scientists.

Specific implications if cooler-than-normal temperatures last (delayed planting for farmers already suffering from lingering drought?) are mixed or unclear. But, generally speaking, we’re headed for a new normal of weather, which may be anything but normal, even year to year.

This is me trying to restart the blog by not focusing on writing my damned thesis.
