The foremost scientist espousing the anthropogenic global warming theory is James Hansen of NASA. Hansen is a fanatic who has been one of the sources of fudged data offered in support of AGW. His boss at NASA was John Theon; Theon, like many other scientists, has now come out as a global warming skeptic.
Theon’s credentials are impressive; here is his resume: Education: B.S. Aero. Engr. (1953-57); Aerodynamicist, Douglas Aircraft Co. (1957-58); As USAF Reserve Officer (1958-60),B.S. Meteorology (1959); Served as Weather Officer 1959-60; M.S, Meteorology (1960-62); NASA Research Scientist, Goddard Space Flight Ctr. (1962-74); Head Meteorology Branch, GSFC (1974-76); Asst. Chief, Lab. for Atmos. Sciences, GSFC (1977-78); Program Scientist, NASA Global Weather Research Program, NASA Hq. (1978-82); Chief, Atmospheric Dynamics & Radiation Branch NASA Hq., (1982-91); Ph.D., Engr. Science & Mech.: course of study and dissertation in atmos. science (1983-85); Chief, Atmospheric Dynamics, Radiation, & Hydrology Branch, NASA Hq. (1991-93); Chief, Climate Processes Research Program, NASA Hq. (1993-94); Senior Scientist, Mission to Planet Earth Office, NASA Hq. (1994-95); Science Consultant, Institute for Global Environmental Strategies (1995-99); Science Consultant Orbital Sciences Corp. (1996-97) and NASA Jet Propulsion Lab., (1997-99).
As Chief of several NASA Hq. Programs (1982-94), an SES position, I was responsible for all weather and climate research in the entire agency, including the research work by James Hansen, Roy Spencer, Joanne Simpson, and several hundred other scientists at NASA field centers, in academia, and in the private sector who worked on climate research. …
[James Hansen] was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). He thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress.
My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit. Furthermore, some scientists have manipulated the observed data to justify their model results. In doing so, they neither explain what they have modified in the observations, nor explain how they did it. They have resisted making their work transparent so that it can be replicated independently by other scientists. This is clearly contrary to how science should be done. Thus there is no rational justification for using climate model forecasts to determine public policy.
This is one of the bluntest repudiations of global warming hysteria I have seen by an eminent scientist in the field. Sadly, we now have global warming hysterics in charge of environmental policy in the Obama administration.
