For the last couple of weeks, our weather here in Eastern Massachusetts has veered back and forth between temperatures in the 50s and the 80s, sometimes even on the same day. Back in March, we were hit with a trio of huge rain storms that caused “100-year” flooding, but which would have been paralyzing blizzards had the traditional colder temperatures of that time of year been in effect. Those of us who suffer from tree pollen allergies can attest that allergy season this year started early and has gone hard.
But, of course, as the Republicans of Maine point out, global climate change is nothing but a conspiracy of government and big business.
This article in The Economist by John Parker considers the blurring of the transitions between the four seasons as the entire globe gets and stays warmer and how it shows itself especially in the tropical climates, where seasonal variation was even more pronounced than here in the north and is felt even more strongly in its disruption of natural cycles in agriculture and among the flora and fauna.
