In Britain, a university climate scientist has stepped down pending the result of a probe into the controversial disclosure of thousands of internal emails on global warming. Phil Jones says he will temporarily leave his position as head of the Climatic Research Unit at the University of East Anglia in England. The school says a computer hacker illegally obtained emails between British and American scientists. Deniers of global warming say the emails provide evidence of an effort to silence academics who have questioned or downplayed human-driven climate change. But the academics say the emails were based on disputing academics who used flawed science to question global warming.
