A Cloudy Mystery
August 2007
By Alan Caruba
There’s a reason why one should be extremely wary of the computer models that are cited by the endless doomsday predictions of Al Gore, the UN’s International Panel on Climate Change, and all the other advocates of "global warming."
The reason is clouds. Computer models simply cannot provide for the constant variability of clouds, so they ignore them.
In a July issue of The Economist there was an article, "Grey-Sky thinking" subtitled, "Without understanding clouds, understanding the climate is hard. And clouds are the least understood part of the atmosphere." Since the increasingly rabid claims of Earth’s destruction from rising temperatures depend on computer modeling, how can they be regarded as accurate if they must largely exempt or deliberately manipulate the impact of clouds?
How can you make predictions, whether it’s a week or a decade from now, if you haven’t a clue why clouds do what they do?
Tim Garrett, a research meteorologist at the University of Utah, with refreshing candor has said, "We really do not know what’s going on. There are so many basic unanswered questions on how they (clouds) work." And that is never mentioned in the great "global warming" debate, one we are continuously told is "decided" and upon which there is a vast scientific "consensus."
This is particularly significant because clouds act to both cool and warm the Earth. It is widely believed that high clouds can reflect solar radiation away from the planet, but they can also serve to trap heat in the atmosphere. New studies, however, have given some cause to reconsider this. Moreover, cloud droplets can last for less than a second while whole clouds can live out their lives in minutes or days. There is no way to integrate such massive, constant change into a computer model that divides the world into boxes up to sixty miles on a side, so they mostly do not.
