Clouds are the Earth’s Blanket

out110out29I bet you have heard me say, “The clouds act like a blanket” to keep our temperatures from falling colder than what they are. It is true that the effects of having cloud cover at night helps, but it works in a much different more scientific way.
The Earth is always radiating infrared energy away into the atmosphere. Molecules of gas in the air, such as water vapor absorb some of the energy. They then radiate that energy in all different directions, including back to Earth. All this energy being absorbed and re-released helps the atmosphere lose more heat on a clear night.
When there are clouds around, the tiny cloud droplets absorb more energy and keep it. As the energy is absorbed, it heats the droplets, causing it to radiate energy back to Earth keeping it warmer at the surface.
