In recent years, much publicity and fear has been generated concerning the idea of "Global Warming" / "Climate Change." In addition, a large number of
people around the world are convinced that Global Warming is due to human behavior to a significant degree (especially the burning of fossil fuels),
and they are urging that sweeping political action be taken to force people to change their life-styles in order to "save the world" from this feared
warming trend. ...However, do the facts demonstrate that this truly is a fearfully threatening concern?
Before governments and nations become overly anxious, and encur a lot of expense, and change whole economies, we must put the Global Warming / Climate
Change issue into long-term perspective. -- Of course, this can't be properly done by considering the temperature measurements of a few years or
decades ...but we need to look at centuries and ideally hundreds of millennia, if possible.
Fortunately, such long-term evidence is apparently available, as we consider the following "Paleomap" put together by Dr. C. R. Scotese, of the
University of Texas
