Precipitation Patterns due to Global Heating

A new very interesting study by the brilliant L. David Roper looking @ precipitation patterns is a must read!!

Here is the introduction:

Global Heating causes more moisture to be evaporated into the atmosphere from land and seas. Therefore, the average precipitation over the Earth increases as global heating increases.
Therefore, it is expected that land masses whose area is small compared to its boundary with seas should have the most increase in precipitation as global heating increases. And land masses whose area is large compared to its boundary with seas may decrease in precipitation as global heating increases.
These rules may not hold in every case; prevailing winds and the existence of mountain ranges may have large effects.
