On The Hijacking of the American Meteorological Society (AMS)
Below is the introduction to a paper being circulated by Bill Gray, Professor Emeritus, Colorado State University and AMS Fellow, Charney Award recipient, and a member of AMS for over 50-years. The full paper can be obtained from Prof. Gray: Gray@Atmos.ColoState.Edu
I am appalled at the selection of James Hansen as this year's recipient of the AMS's highest award - the Rossby Research Medal. James Hansen has not been trained as a meteorologist. His formal education has been in astronomy. His long records of faulty global climate predictions and alarmist public pronouncements have become increasingly hollow and at odds with reality. Hansen has exploited the general public's lack of knowledge of how the globe's climate system functions for his own benefit. His global warming predictions, going back to 1988 are not being verified. Why have we allowed him go on for all these years with his faulty and alarmist prognostications? And why would the AMS give him its highest award?
By presenting Hansen with its highest award, the AMS implies it agrees with his faulty global temperature projections and irresponsible alarmist rhetoric. This award, in combination with other recent AMS awards going to known CO2 warming advocates, is an insult to a large number of AMS members who do not believe that humans are causing a significant amount of the global temperature increase. These awards diminish the AMS's sterling reputation for scientific objectivity.
Hansen previously studied the run-away greenhouse warming of Venus. He appears to think that man's emittance of CO2 gases, if unchecked, will eventually cause the Earth to follow a similar fate. Hansen's arrogance and gall over the reality of his model results is breathtaking. He has recently warned President Obama that our country has only 4 years left to act on reducing CO2 gases before the globe will reach a point of irretrievable and disastrous human-caused warming. How does he know what thousands of us who have spent long careers in meteorology-climatology do not know?
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 years and why there has been a weak global cooling between 2001 and 2008. Hansen and his legion of environmental-political supporters (with no meteorological-climate background) have done monumental damage to an open and honest discussion of the Anthropogenic Global Warming (AGW) question.
He and his fellow collaborators (and their media sycophantic followers) are responsible for the brainwashing of a large segment of the American public about a grossly exaggerated human-induced warming threat that does not exist. Most of the 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 (see the Appendix for scientific discussion). These changes are not associated with CO2 increases.
Hansen has little experience in practical meteorology. He apparently does not realize that the strongly chaotic nature of the atmosphere-ocean climate system does not allow for skillful initial value numerical climate prediction. Hansen's modeling efforts are badly flawed in the following ways: His upper tropospheric water vapor feedback loop is grossly wrong. He assumes that increases in atmospheric CO2 will cause large upper-tropospheric water vapor increases which are very unrealistic. Most of his model warming follows from his invalid water vapor assumptions.
His handlings of rainfall processes are, as with the other global climate modelers, quite inadequate. He lacks 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. He does not have these ocean processes properly incorporated in his model.
He assumes the physics of global warming is entirely a product of radiation changes and radiation feedback processes. This is a major deficiency.
Hansen's Free Ride.
It is surprising that Hansen has been able to get away with his unrealistic modeling efforts for so long. One explanation is that he has received strong support from Senator/Vice President Al Gore who for over three decades has attempted to make political capital out of increasing CO2 measurements.
Another reason is the many environmental and political groups (including the mainstream media) who are eager to use Hansen's modeling results as justification to push their own special interests that are able to fly under the global warming banner.
A third explanation is that he has not been challenged by his peer climate modeling groups who apparently have seen possibilities for research grant support and publicity gains by following Hansen's lead.
Yet another reason has been the luck of his propitious timing. His 1988 Senate testimony occurred after there had been global warming since the mid-1970s and we were experiencing a hot summer. And the global warming that occurred over the next 10 years (to 1998) gave an undeserved justification to his CO2 warming claims. Had Hansen given his Senate testimony in the 1970s or today (since we have seen weak global cooling since 2001) his alarmist rhetoric would have been taken much less seriously.
I anticipate that we are going to experience a modest naturally-driven global cooling over the next 15-20 years. This will be similar to the weak global cooling that occurred between the early-1940s and the mid-1970s. It is to be noted that CO2 amounts were also rising during this earlier cooling period which was opposite to the assumed CO2 temperature relationship.
