In a recent letter, W.H. Haynes confused weather and climate when he implied that the recent cold weather somehow negates global warming ("Where’s Al Gore?" Dec. 13). Weather refers to short-term variations in temperature, precipitation, wind, etc. Climate refers to long-term trends over decades.
While global warming is only one factor that affects our weather, it definitely has an influence. Last July was the hottest summer ever recorded in Salt Lake City. And while we are now shivering with an inversion, we forget that it was colder in the past. The record cold was recorded in 1932 when the temperature plunged to minus 20 degrees.
