The Science Behind Global Warming...

As I have said many times, the science behind the theory that humans have caused global warming is shaky, at best. Yes, the earth is slowly warming, but that is most probably due to natural forces. Here's a good overview of the science, and differences between scientists...

Against the background of these practices it is surprising that we have often been told that 'the science is settled' and 'all scientists agree'. This is simply not true. Tens of thousands of bona fide qualified scientists have expressed their reservations as regards the man-made global warming hypothesis (see: http://www.oism.org/pproject/s33p428.htm. But it could perhaps be argued that most of them were not meteorologists and/or climatologists. What about this latter category? At a recent climate change seminar, organised by the (classical liberal) Friedrich Naumann Foundation, together with the Society for the Freedom of Science, in Gummersbach (near Bonn), Prof. Dennis Brays presented the results of a survey among some 500 German and European climate researchers. They showed that the much-repeated claim of a 'scientific consensus' on anthropogenic global warming is not correct. According to the results, some 25% of European climate researchers who took part in the survey still doubt whether most of the moderate warming during the last 150 years can be attributed to human activities and CO2 emissions.

But perhaps these climate researchers are not connected with the IPCC. There will surely be a consensus within the IPCC? Again, no. Even within the IPCC there are differences of view. John Christy is one of the lead authors of the IPCC. He is professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville. He is a specialist in satellite temperature measurements. Together with his colleague Roy Spencer of the same institute, he wrote a paper, 'Global Temperature Report 1978-2003', http://uahnews.uah.edu/pdf/25years.pdf, dismissing much of the scare-mongering by his IPCC colleagues.
