Global Warming crowd resemblels Galileso's persecutors

Mr. Gale (4/2/11 Des News) means well, but he errs when he concludes that man causes climate change (he means global warming), claiming that all scientists believe and only self-serving politicians don’t. He ventures far beyond his literary area of expertise. Many reputable scientists believe any global warming represents earth’s own cycles, not man’s actions. The know-it-all so-called scientists clamored in the ‘50s that we were suffering a disastrous global cooling trend – beginning a new ice age. They were wrong then too. Ironic how the man-is-central attitude of these supposedly enlightened ones resembles the attitude of those who persecuted Galileo for stating that the sun rather than the earth was center of the solar system. Both crowds dangerously over-inflate the place of man in affairs of the heavens.
