While few U.S. politicians bother to question whether humans are changing the world's climate -- nearly three years ago the U.N. Intergovernmental Panel on Climate Change concluded the evidence was unequivocal -- public debate persists. And the newly disclosed private exchanges among climate scientists at Britain's Climate Research Unit of the University of East Anglia reveal an intellectual circle that appears to feel very much under attack, and eager to punish its enemies.
In one e-mail, the center's director, Phil Jones, writes Pennsylvania State University's Michael E. Mann and questions whether the work of academics that question the link between human activities and global warming deserve to make it into the prestigious IPCC report, which represents the global consensus view on climate science.
"I can't see either of these papers being in the next IPCC report," Jones writes. "Kevin and I will keep them out somehow -- even if we have to redefine what the peer-review literature is!"
