Speaking of Ohio................

About 17,000 years ago, a long time to us humans, but a blink of an eye in the great geologic scheme of things, much of Ohio was covered under a sheet of ice.  Those who know these sorts of things estimate that the ice sheet may have been a 1,000 feet thick in the center of our fine State.  That's a lot of ice.  Casual readers may sense that this blogger doesn't get all excited about the problem of "global warming."  This is mostly because Ohio has been glaciated more than once, and sensing there is some natural variation in climate, and also sensing mankind is fairly clever at problem solving, he prefers warming to cooling.
