The science behind the theory of anthropogenic global warming (AGW), or manmade climate change, has been said to be ‘settled’.  The United Nation’s Intergovernmental Panel on Climate Change (IPCC), Al Gore, and Dr. James Hansen make up a triumvirate of climate change advocates.  Wielding studies, computer models, and various charts and analyses, they believe man is heading down the road to self-destruction of we do not reverse course immediately and do everything and anything to stop what they believe is an unnaturally warming climate.

Last week we first brought to light a letter by Dr. William Gray, Professor Emeritus of Colorado State University, admonishing the American Meteorological Society’s decision to give its highest award to Dr. James Hansen.  Hansen is head of NASA’s Goddard Institute for Space Studies (GISS), an astronomer, and a very divisive figure in the global warming debate. 

We continue our analysis of not only the battle between Dr. William Gray and Dr. James Hansen but the larger issue of anthropogenic global warming.  In his letter Dr. Gray raises some very interesting arguments about Hansen’s research and about the science behind the theory of AGW.  Today we take a closer look at the science as Dr. Gray sees it.

Last week we wrote about an extremely strongly worded letter from William Gray to the American Meteorological Society (AMS) objecting to their awarding James Hansen their highest award.  This letter pits two of the giants in meteorology and climatology against each other in the debate over manmade climate change and global warming. 

The letter itself (available here on icecap.us) takes issue with some of the decision making processes within the AMS which is not particularly relevant to us.  What is revealing however is Dr. Gray’s arguments against the global warming theory and Dr. Hansen’s research.  Today we will take a look at the discussion in the letter about Dr. Hansen himself and his credentials.

For those that aren’t familiar with him, Dr. Gray is a Professor Emeritus of Colorado State University who is best known for his hurricane forecasts.  He is a highly trained and respected meteorologist with decades of practical experience in monitoring the earth and its climate.

In the letter he points out that Dr. Hansen, head of NASA’s Goddard Institute for Space Studies (GISS), is not a trained climatologist nor a meteorologist.  His formal background is actually in astronomy which does make one wonder how he has become one of the primary mouthpieces for anthropogenic global warming (AGW), or manmade climate change.
