I think I am a reasonably bright guy. But I also think that I generally know when I am in the company of people that are truly gifted. This is such at time.
A collection of former astronauts and the NASA employees that put them in space have signed an open letter calling on NASA to stop endorsing/encouraging opinions that suggest that we are on the cusp of catastrophic global warming.
As former NASA employees, we feel that NASA’s advocacy of an extreme position, prior to a thorough study of the possible overwhelming impact of natural climate drivers is inappropriate. We request that NASA refrain from including unproven and unsupported remarks in its future releases and websites on this subject. At risk is damage to the exemplary reputation of NASA, NASA’s current or former scientists and employees, and even the reputation of science itself.The letter is longer, but the above gets right to the point. Climatology has been inhabited by pseudo-scientists for far too long. The computer models that such folks have developed have invariably predicted temperature changes that
Traditional scientists would have sought to adjust their theories...as expressed by their models...to fit the facts. The more extreme and vocal climatologists do not follow such a traditional scientific method.
The former astronauts and NASA employees do not say that global warming isn't happening. They do not say that CO2 isn't a factor. They do not say that humanity isn't responsible.
They are saying that process of studying the climate has deviated from the strong scientific basis that used to be the hallmark of NASA endeavors.
