Republican Rep. Todd Akin's decision to stay in the U.S. Senate race in Missouri is likely to leave him with support from the state's evangelical community, but not much more, says a political scientist at the University of Missouri, St. Louis.
Ten years ago, a piece of ice the size of Rhode Island disintegrated and melted in the waters off Antarctica. Two other massive ice shelves along the Antarctic Peninsula had suffered similar fates a few years before. The events became poster children for the effects of global warming. But a new study finds that the story isn't quite so simple.
There's no question that unusually warm air triggered the final demise of these huge chunks of ice. But a lingering question is whether these events can be attributed to human-induced global warming.
