Stick to politics, Rush, don't try science

The laugh of the day comes from the Rush Limbaugh program. While discussing, rightly, the inconsistency of a report in Science that air pollution is down, causing clearer skies and more global warming, Rush questioned the article in that the clearer skies would increase the speed of light and more of it would bounce off. His conclusion that the global warming mythologist use any event as evidence of global warming, including decrease in pollution (or an increase in pollution) to advance their myth is absolutely right. He should just stay out of science.

I doubt very seriously that the speed of light will be affected at all by what is in the earth's atmosphere. The speed of light is a "constant." The GW mythologists are correct in that the less particulate in the sky the more sunlight gets through and the more the earth will be warmed. Don't believe me, check the warming on a clear day versus a cloudy day. Are you cooler in the shade or in the sun?

All that said, we just don't know the "energy budget" of the earth, including net solar heating. The impact has recently been revised downward. The science of global warming is, at best, unsettled.

Rush should stick to politics, you don't need any real facts. The global warming mythologists should stay away from politics, they need real facts.
