Mechanics of climate change

 

Fourier did the first heat balance on the earth over 200 years ago and the first detailed prediction of global warming was carried out by Arrhenius over 100 years ago;- calculation done by old fashioned paper and pencil, nothing mystical here.  He came to the same basic answer that all our high tech computers have reached.  This is not based on some hyper technology, when light of a certain wave length will pass through a gas some energy will pass straight through, some will be absorbed and some will be bounced back.  The ratios can be readily measured by apparatus developed over 150 years ago.

 

In the same way when light lands on the surface of the earth some will be absorbed and the balance will be reflected back, but at a different wave length.  This is all simple physics which has been around for hundreds of years and is totally accepted.
