The recent major snow storm in the Northeast inevitably confirmed climate change doubters’ convictions. However, dramatic swings in temperature are also part of the changing climate, and the overall trend is unquestionably one of shorter winters.
The U.S. Geological Survey says spring is showing up two to three weeks earlier than normal in the southeast United States this year, from Texas to Washington, and is making its way gradually north. This scientifically-proven phenology finding is based on flowering and leafing out times. In the Arctic, some grasses are flowering a month early, depriving hibernating animals of a crucial early-spring food source. Snowshoe hares and ermine are failing to molt their white winter coats before the world turns green, leading to less successful protection (and for the ermine, predation) for these animals. The climate scientists have it right, regardless of the white world outside our windows — New York City’s forecast is for the mid-60’s on Wednesday. Who knows what flowers we’ll find when the snow soon melts – perhaps the unfurling flower buds of Round-leaved Hepatic (pictured).
