Proof of warming
Re: “Difference in temperatures between Stapleton, DIA,” July 10 letter to the editor.
Barry Schwartz alleges that global warming alarmists are “coming out of the woodwork’’ because of Denver’s record heat. In fact, the proof of global warming are the photos from space that document shrinking polar ice caps, combined with rising oceans and an increase in the average annual global temperatures based on weather data from official weather stations all over the world.
It is surprising that Schwartz, a retired meteorologist, points to a frigid winter in Alaska and a cool summer in Europe to refute global warming, which by definition can only be determined by worldwide averages,not local anachronisms.
