House Republicans pointed to controversial e-mails leaked from climate scientists and said it was evidence of corruption. Top administration scientists looking at the same thing found no such sign, saying it doesn't change the fact that the world is warming.

The e-mails from a British university's climate center were obtained by computer hackers and posted online about two weeks ago. Climate change skeptics contend the messages reveal that researchers manipulated and suppressed data and stifled dissent, and conservative bloggers are dubbing it "Climategate."
