In order to make a case for global warming, scientists have to somehow come up with an “average” temperature for the planet. But according to a recent report published by a trio of professors, coming up with any kind of meaningful temperature for an ecosystem as complex as the earth is impossible.
While it is possible to treat temperature statistically locally, it is meaningless to talk about a a global temperature for Earth. The Globe consists of a huge number of components which one cannot just add up and average. That would correspond to calculating the average phone number in the phone book. That is meaningless. Or talking about economics, it does make sense to compare the currency exchange rate of two countries, whereas there is no point in talking about an average ‘global exchange rate’.
The professors’ thesis has come under attack, of course, but at least it adds another topic for discussion to the debate — which is still ongoing, despite rumors to the contrary.
