Re: Global Warming? My A$$ Its Cold Outside
Quote:
Scientists crediting the warming of the Earth to human activity describe it as follows. The sun radiates heat toward the Earth, and it is indeed the ozone layer in the atmosphere that prevents all of the heat being radiated from the sun from hitting the planet. For the heat that does reach the Earth, however, much of it is radiated back into the atmosphere toward space. However, the greenhouses gases in the atmosphere (carbon dioxide being a primary one) trap the heat being radiated back into space. These gases have existed in the atmosphere for millions of years, and they have effectively helped the planet maintain a temperature that has allowed life to form. But the inordinate amount of carbon dioxide being shot into the atmosphere by humans is intensifying the "trapping" character of the gases, which results in a level of warming that is higher that is generally experienced in natural climatic cycles. So, basically, it is not a de-insulation, but rather an increased insulation. That's at least how I've understood it. Feel free to enlighten me more. |
