In recent months lots of Newspaper Headlines have ranted and raved about Global Warming. What they keep yelling about is Greenhouse Gases, Carbon Dioxide, and Methane.
I would like to ask each of you if those gases heat up as fast as BLACK ASPHALT PAVEMENT? Is it possible that carbon dioxide retains heat as long as BLACK ASPHALT PAVING?

Black helps to retain the heat on the earth yes, but the major problem is the ocean's. The less ice there is to reflect the sun's ray's back out of our atmosphere the more heat is absorbed by our oceans.

Carbon Dioxide does NOT absorfb the heat. Rather it acts like a mirror and reflects infrared radiation BACK to the lower atmosphere, trapping the heat in the lower levels of the air. What happens is : as sunlight hits the earth's surface it is changfed ot infrared heat. Carbondioxide it transparent to Visible light but is opque to infrared and reflects it back toward the source of the infrared (in this case, the ground). Asphalt CAN act as a heat sink and retain the warmth of the sunlight for a period of time but is NOT much of a contributing factor in Glabal warming, other than serving as a place to run Carbon emitting vehicles which spew off greenhouse gases.

Black pavement is not a significant factor. Scientists don't guess about stuff like this. They measure it. And the data shows it's not a big deal. More here:
