For those of us reared before the 1970s, childhood unfolded in a procession of seasons. Each had a distinct character. Transitions between them were tender trends.
Then, incongruity. Cross-country skis stayed in the garage. Slopes not dressed by snow-making tended to stay brown. A couple of summers wilted crops and exposed streambeds—not inconceivable, but still. Spring and fall shrank to mere days.
In retrospect, such flux was symptomatic of global warming. Now, as warming has continued and underlying influences scientists call “forcings” have come to bear, a third pattern is emerging, if one can pardon the term pattern. Surprise is the order of this new day—this winter’s record-shattering warmth being but one example. Local weather forecasting seems at times to resemble spinning a roulette wheel, so regional and national trends and probabilities are the new measures of accuracy. Meteorologists, many still skeptical of climatology, are—whether they realize it or not—fighting a rear-guard action.
