University of Copenhagen Professor Bjarne Andresen has analyzed the topic in collaboration with Canadian Professors Christopher Essex from the University of Western Ontario and Ross McKitrick of the University of Guelph.
"It is impossible to talk about a single temperature for something as complicated as the climate of Earth," said Andresen, an expert on thermodynamics. "A temperature can be defined only for a homogeneous system. Furthermore, the climate is not governed by a single temperature. Rather, differences of temperatures drive the processes and create the storms, sea currents, thunder, etc. which make up the climate".
He says the currently used method of determining the global temperature -- and any conclusion drawn from it -- is more political than scientific.
Al Gore thought he was ‘home free’ with his quasi-documentary scare film. If scientists around the world keep stepping forward challenging the man-made global warming myth, will Gore back down and revise his movie or quietly stop promoting it and let it die?
