Land Surface Evaporation Increased During The Second Half Of The 20th Century

ScienceDaily (November 8, 2006)

New research shows through a mathematical model how lower pan evaporation rates actually indicate higher terrestrial evaporation, in spite of global dimming. Thus, while global dimming had an effect, it was not strong enough to cause a negative trend in evaporation where pan evaporation had been observed to decrease.

In arid climates, terrestrial evaporation is low. However, water in pans left out in this environment can evaporate huge amounts of water. By contrast, water in pans left out in a more humid environment due to increased precipitation will tend to lose less water because of the ambient humidity
