Document Summary

If we plug in the numbers we get a temperature of 255k while the actual temperature of the earth is 288k, meaning that greenhouse impact is 33k. Note that the atmosphere is mainly transparent to solar radiation but absorbs strongly terrestrial radiation. The absorption of terrestrial radiation is mainly by. Other ghg are carbon dioxide (co2), methane (ch4), Shows how different wavelengths are absorbed by different ghg. Absorption (%) is for all the ghg combined, that get trapped in the atmosphere (heating of atmosphere). Also note that shorter wavelengths are usually warmer. The absorption of radiation cause the carbon dioxide or water molecules to vibrate and rotate, hence sending radiations back in every way. Note that water volume can vary a lot depending on the location (higher in tropics then poles, per instance) There must be a balance between incoming and outgoing radiations energy for the.
