It's a topic that is likely to come up more and more after President-elect Barack Obama moves into the White House next week. Obama has said that preventing and reversing global warming will be a top priority in his administration—a change from the previous administration's stance that voluntary efforts would be enough—likely through a mandatory cap-and-trade scheme.
Under that type of program, the government sets a cap or overall level for pollution and polluters can trade licenses to pollute to keep within their levels. But opponents of such a scheme note that such a move would ultimately drive up energy costs, because power plant owners will pass along to consumers the costs of staying within the mandatory limits.

Despite broad consensus on the existence, origins and potentially catastrophic effects of global warming, a vocal minority continues to question the motives, methods and assumptions of climate scientists sounding the alarm. So when temperature data released by NASA's Goddard Institute for Space Studies (GISS), one of the leading monitors of climate change, showed an unusually warm October, climate change skeptics cried foul.
As it turned out, the GISS data were flawed. The relatively minor glitch was fixed and the figures updated. End of story? Of course not. Climate change skeptic Anthony Watts called the mistake a "data train wreck" in his blog. Global warming denier Christopher Booker, in a column in the U.K.'s conservative Telegraph, called the error a "surreal scientific blunder."
