What is the Greenhouse Effect?

June 15, 2007 · Filed Under Uncategorized

Greenhouse gases trap heat energy, reducing the amount that is radiated from the earth back into space, acting as a partial blanket and causing a difference of about 21ºC between the average temperature that we would have and the actual average of the earth surface temperature. If there were no greenhouse gases the earth would not be habitable for humans.If a certain level of greenhouse gases warms the earth by about 21ºC, it would not be surprising if higher levels would warm it further and this is exactly what is happening.
