The Shame of the American Meteorological Society

Bill Gray, a professor emeritus at Colorado State, has been a member of the American Meteorological Society for more than 50 years. In a lengthy post at Watts Up With That, he expresses his dismay at the manner in which AMS has sold out science in the interest of politics:

I am very disappointed at the downward path the AMS has been following for the last 10-15 years in its advocacy of the Anthropogenic Global Warming (AGW) hypothesis. The society has officially taken a position many of us AMS members do not agree with. We believe that humans are having little or no significant influence on the global climate and that the many Global Circulation Climate Model (GCMs) results and the four IPCC reports do not realistically give accurate future projections. To take this position which so many of its members do not necessarily agree with shows that the AMS is following more of a political than a scientific agenda. …
We AMS members have allowed a small group of AMS administrators, climate modelers, and CO2 warming sympathizers to maneuver the internal workings of our society to support AGW policies irrespective of what our rank-and-file members might think. This small organized group of AGW sympathizers has indeed hijacked our society.
James Hansen’s predictions of global warming made before the Senate in 1988 are turning out to be very much less than he had projected. He cannot explain why there has been no significant global warming over the last 10-12 years.
Many of us AMS members believe that the modest global warming we have observed is of natural origin and due to multi-decadal and multi-century changes in the globe’s deep ocean circulation resulting from salinity variations. These changes are not associated with CO2 increases. Most of the GCM modelers have little experience in practical meteorology. They do not realize that the strongly chaotic nature of the atmosphere-ocean climate system does not allow for skillful initial value numerical climate prediction. The GCM simulations are badly flawed in at least two fundamental ways:
1. Their upper tropospheric water vapor feedback loop is grossly wrong. They assume that increases in atmospheric CO2 will cause large upper-tropospheric water vapor increases which are very unrealistic. Most of their model warming follows from these invalid water vapor assumptions. Their handlings of rainfall processes are quite inadequate.
2. They lack an understanding and treatment of the fundamental role of the deep ocean circulation (i.e. Meridional Overturning Circulation – MOC) and how the changing ocean circulation (driven by salinity variations) can bring about wind, rainfall, and surface temperature changes independent of radiation and greenhouse gas changes. These ocean processes are not properly incorporated in their models. They assume the physics of global warming is entirely a product of radiation changes and radiation feedback processes. They neglect variations in global evaporation which is more related to surface wind speed and ocean minus surface and air temperature differences. These are major deficiencies.
It is surprising that GCMs have been able to get away with their unrealistic modeling efforts for so long. One explanation is that they have received strong support from Senator/Vice President Al Gore and other politicians who for over three decades have attempted to make political capital out of increasing CO2 measurements. Another reason is the many environmental and political groups (including the mainstream media) have been eager to use the GCM climate results as justification to push their own special interests that are able to fly under the global warming banner.

To put it less delicately, an enormous amount of money has flowed into the global warming movement. It is lavishly funded, mostly by governments. For an AGW enthusiast to admit that his models are patently wrong would mean an end to the gravy train. Hence the ongoing frauds that are perpetrated in the name of climate change.
