Reports about the melting ice caps are distressing, but for the most part climate change remains abstract. The poor polar bear has been trotted out as the tangible face of global warming so often that we're beginning to see "polar bear fatigue." How about bringing the effects of Arctic melt close to home, as in what it will cost? A new study does just that, and the results are alarming, not just for Arctic dwellers but for all of us. According to lead author Eban Goodstein, Ph.D., over the next 40 years Arctic ice melt will take an economic...
...Cost of a Warming Arctic" study, funded by the Pew Environment Group, assessed trends in the Arctic's cooling mechanisms and examined the financial consequences. The research team looked at the rate at which surfaces change from white ice and snow to ocean or exposed tundra, since darker surfaces absorb, rather than reflect, solar heat. According to the report, this shift and the increased methane emissions linked with melting permafrost currently slap us with annual losses in the range of $61 billion to $371 "resulting from such changes as heat waves and flooding." But the anticipated monetary fallout described...
...still evolving. "It's a slow process," he says, noting that while there is documentation on rising sea levels, there are little data on such factors as methane release from melting permafrost, the impacts of ocean acidification, and the timing of the potential disintegration of the West Antarctic Ice Sheet. "We as social scientists can't [offer precise financial estimates] until we have reliable information from natural scientists. We will probably get better resolution over the next two decades."

...year, with much tub-thumping about how A-list directors like Steven Spielberg and James Cameron were testing the format. The box office verified that interest: four of the top dozen domestic hits of 2009 were shown in 3-D. Three were animated features: Up, Monsters vs Aliens and Ice Age: Dawn of the Dinosaurs. The fourth film: Avatar. James Cameron's eco-epic, which quickly became the No. 1 moneymaker in movie history, proved a couple of things about 3-D. In the right hands, the technology was an amazingly supple tool, allowing film people to create worlds that...
