Hansen's Claims About Global Warming Embarrassed NASA

Hansen Embarrassed NASA
02/01/09 - PowerLineBlog by John Hinderaker

James Hansen of NASA is a leader in espousing the theory of Anthropogenic Global Warming (AGW). He has public credibility because of his NASA affiliation. His boss at NASA was John Theon, who has recently retired, and has announced his view that AGW is not supported by evidence.

Theon writes:

[edited] 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 position, that NASA did not know enough to forecast climate change or mankind's effect on it. He embarrassed NASA by his claims of global warming in his 1988 testimony before Congress.

I believe 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. They don't explain what they have modified in the observations or 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.

Global Warming Caused by Humans is a Scam
