| As sunlight enters the atmosphere, a portion is immediately reflected back to space, but the rest penetrates the atmosphere and is absorbed by the earth's surface. This energy is then remitted by the earth back into atmosphere as long-wave radiation. Carbon dioxide and water molecules absorb this energy and emit much of it back towards the earth again. This delicate exchange of energy between the earth's surface and atmosphere keeps the average global temperature from changing drastically from year to year. This study shows without a doubt that our activities as humans are changing the makeup of the upper atmosphere adding water vapor. That water vapor is heating our planet and in turn the heating adds more water vapor to the Upper-Troposphere in the mother of all feedback loops contributing to Global Warming. |
