Question

How are the changes in atmospheric carbon dioxide described

Answer 1

Well what i think this is my idea about it.
Carbon Dioxide, and other greenhouse gases, have the ability to absorb specific wavelengths of radiation, gain energy which they transfer to other molecules, then release the energy to be absorbed by another similar molecule. This is known as the greenhouse effect. These gases, which comprise less than 2% of the total atmosphere, keep the temperatures about 33 degrees warmer than if they were not present. Of course an increase of these gases would allow the greater trapping of energy, as has been witnessed by both the IMG and IRIS satellites. As more trapping of radiation occurs the tropopause, or the boundary between the troposphere and the stratosphere due to tropospheric warming and stratospheric cooling, increases in altitude, which is what we see occurring, Glaciers retreat on average on a worldwide scale which we are witnessing, as measured by the GRACE satellite. Animal migratory habits are also currently for a warming climate. etc..
