It would be more accurate to say that Hansen has found it necessary to rewrite his own science.
From MonroeDNA's post
NASA's James Hansen now predicts precisely the same, small amount of warming in the next 50 years that the much-derided "climate skeptics" predicted all along. According to both the skeptics and Mr. Hansen, the planet is destined for a mere 0.7 degree Centigrade (1.25 degree Fahrenheit) warming between now and 2050
True, but I try not to change the title of the articles I post. Normally they are as much a part of the issue as the body of the text itself. Here the story might well be that he is shrouding his past short comings in accusing the goverment of doing what he himself is doing.
I also though caution that it is proper in science for a person to revise their earlier finidings. If he has continued to study the subject he should either find more support for his earlier hypothesis, or change his hypothesis. If he did not do so that would make him even worse. I agree with an earlier poster that said the government does hold a heavy hand over scientists in this country, but that comes from most of the money coming from government. Sad, but true.
