In his latest global warming denial column, Art Hall enlightens us all about the wide swings in climate the planet has endured over millions of years as an explanation for today's fuss-over-nothing about global warming. Wow! How could the world's climate and computer scientists, geographers, anthropologists, and a bevy of other NASA scientists all miss the boat on that startling explanation? What an insult to all scientists. It's akin to a professor teaching American history disregarding the American Revolution. Please don't insult us anymore with your sophomoric myths and spin.
