Al Gore helping global warming to save humanity, not to become a billionaire
Reporting from Washington - Citing e-mails that critics say cast doubt on global warming, congressional Republicans called on the Obama administration Wednesday to suspend efforts to combat climate change until the controversy is resolved.
In a letter to the Environmental Protection Agency, the lawmakers requested that a pending move to regulate greenhouse gases under the Clean Air Act be halted, along with plans to limit emissions from vehicles, power plants and other sources, "until the agency can demonstrate the science underlying these regulatory decisions has not been compromised."
At issue are more than 1,000 electronic messages that were apparently obtained and released by a computer hacker. Most involve scientists at the University of East Anglia's Climatic Research Unit in Britain, one of the few institutions in the world that collect the historical temperature data relied on by climate researchers.
At the heart of the controversy is whether human activity causes climate change. Skeptics argue that global temperatures may be warming naturally. They say that the e-mails suggest that scientists may have manipulated evidence to bolster their claims. The scientists dispute that and say that their words have been taken out of context.
