This is the second in a series of reposts from gregladen.com on global warming.
Why Greenhouses have nothing to do with the Greenhouse Effect, and more importantly, why CAN’T I microwave toast?
A greenhouse is a glass house that is sealed to keep air in and insulated to keep heat in but at the same time allow sunlight in. This sunlight contributes to the heat in the greenhouse by warming the ground or other material in the greenhouse, and of course the light energy is used by the plants. But the point of a greenhouse is to keep air that is warmed, by the sun and/or heaters that may be required in the greenhouse, from wafting away.
This is not how the so-called “greenhouse” effect works. There is no thing out there keeping warm air from wafting away from the planet. The air just stays there, greenhouse effect or not, moving around and doing the weather thing, and looking blue much of the time.

The IPCC report is out, “An Inconvenient Truth” has been honored by the academy, a sea change is happening in the way that climate change news is being reported, and you can bet the Right Wing and the Ree-pubs are as we speak working up new Talking Points and Spins to deflate the urgency of the issue. It is an axiom that in reporting science, there are two (not one, not three or four, just two) sides to every issue, and one side is the plank nailed to the Democratic Party Platform, and the other side is the plank nailed to the Ree-pub Party Platform. This is a truth as stable and reliable as the fact that Home Depot will always sell 2″ X 4″ studs and plywood in 4′ X 8′ foot pieces. We are already seeing the dubious dichotomies forming up. For instance, yes, the Antarctic Ice Sheet is sloughing off the continent, but it is opening new and wonderful opportunities for both shrimp and scientists. Yes, global warming is real and is anthropogenic, but the Average American thinks, according to Polls, that it is only the third or fourth most important issue. And so on.
