What a Difference a Day MakesSome mistakenly think each day should be degrees warmer “if there is such a thing as global warming.” They want to think they know what it is without reading any scientific explanation. The global warming article is special in that it does not focus on high temperature, but temperature difference—the high temperature of the day minus the low temperature of the day. This temperature difference is of key importance.
A Two for One SpecialThe conclusions derived during Jon’s discussion would have been sufficient material for a very satisfactory article, but it goes one step further. And that step is a tantalizing one. It involves contrails. On a clear day especially, we may see one or more straight white lines across the blue sky.* These contrails discharge from aircraft. They are narrow at the exit point, but as the aircraft travels on, the atmosphere widens them.
Global Warming – The Human TouchThese temporary, man-made clouds exert an effect on the weather, simply because there are so many of them. What effect, and how was it possible to discern the effect? You’ll want to read Jon’s article for the amazing answer. Truly fascinating stuff. Check it out—what’s ten minutes? I figure you’ll agree it’s time well spent.
* One contrail humorously appears where it should not appear, on an old Daniel Boone movie starring Fess Parker and Jimmy Deane. Keep your eye on the upper left-hand corner of the screen.
