Climate change cover-up? You better believe it
Was Sen. James Inhofe right when he declared 2009 the year of the climate contrarian? A slew of emails stolen from the University of East Anglia's Climatic Research Unit highlight definite character flaws among some climate scientists—including an embarrassing attempt to delete emails that discussed the most recent report from the United Nations Intergovernmental Panel on Climate Change—while also exposing what looks like a failure of scientists to acknowledge a halt to global warming in the past decade.

Is geoengineering humanity's last hope to avoid catastrophic global warming?
Do you really want to start messing with the atmosphere? If not, then stop emitting so much CO 2 . Or so argues the U.K.-based Royal Society, the same people who brought you Isaac Newton, Charles Darwin and Stephen Hawking.
