Taking a walk on the mild side
Weathercasters tell us that “meteorological spring” begins not March 21 but on March 1.
This year, following a December through February that often felt more like a spring than a winter in the Fox Valley, that has been easy to believe. And never easier than last Wednesday and Thursday, when the mercury hovered around the mid-60s degrees. With sunshine.
But if humans, with all our brain power, can be so easily fooled about the calendar, what is this unusual weather doing to local plants and animals? And what will that mean for the next three months when it comes to fighting off pests, nourishing a garden, enjoying wildlife — or dodging tornadoes?
The good news
Yes, the winter that just ended (meteorologically) ended up being a powerful advertisement for global warming — though an advertisement that might have been more convincing if the winter just a year before had not been one of our coldest and snowiest. Northern Illinois temperatures averaged 5 degrees above average for December-February, while snowfall was a whopping 75 percent below average. It was the warmest winter since 1932.
