And their future funding and advancement is tied to their willingness to advance this theory. Computer models are even intentially rigged to ignore natural negative feedback mechanisms to produce scary results. That is how they come up with the ridiculous range of predictions that the earth will warm from 2.5 to 10.7 degrees over the next century. The models at the higher end were intentionally altered to ignore known factors which reduce global warming. They are not an honest bunch as they include those numbers in their range when they talk to the media and publish papers. It is EXTREMELY unlikely that we will warm even 2 degrees over the next hundred years. An honest analysis based on current trends would be -0.5 cooling to 1.0 degree warming. The range 'scientists' publish is simply tin-foil hat kookery.
