With a few--very few--exceptions, real scientists are supposed to document, honestly and completely, their data, and then share that data with other investigators. The global warming guys seemed to have utterly failed to do this.
Jim Lacey nicely summarizes:
Over the years this core group, led by Phil Jones at East Anglia and Michael Mann at Penn State, became so close that even those inclined toward more honest appraisals of the state of climate science were hesitant to rock the boat. As one warm-monger states: “I am not convinced that the ‘truth’ is always worth reaching if it is at the cost of damaged personal relationships.” Silly me, how many years have I wasted believing that the very point of science was to pursue the truth in the face of all obstacles. On the basis of this evidence the scientific method must be rewritten so as to state: “Science must be as objective as possible, unless it offends your friends.” . . .
Why? One e-mail clearly explains what was at stake: ”I can’t overstate the HUGE amount of political interest in the project as a message that the Government can give on climate change to help them tell their story. They want the story to be a very strong one and don’t want to be made to look foolish.” In other words, all the scientific lying was a result of scientists trying to give their political masters a major issue they could use to control people’s lives and justify wasting trillions of dollars.
