Everyone watchout for the greenhouse gases!
http://www.newsweek.com/id/202757?from=rssClimate change is likely to have all sorts of nasty consequences over the next century—among them, according to a brand-new report from the U.S. Global Change Research program, an increase in torrential downpours in the American northeast.
So it was uncomfortably fitting that a major climate-consciousness-raising event took place in just such a downpour. As reporters and dignitaries huddled under leaky tents just outside New York's Madison Square Garden on Thursday, Deutsche Bank switched on its mammoth Carbon Counter billboard. The counter, towering 70 feet above busy Seventh Avenue and dramatically visible to hundreds of thousands of commuters who take the train to and from Penn Station, displays a real-time count of heat-trapping greenhouse gases we're pumping into the atmosphere—about 2 billion metric tons every month, added to the 3.6 trillion tons already floating around up there.
How do they know it's 2 billion tons? Actually, they know it isn't. Although carbon dioxide is by far the most significant human-generated greenhouse gas, it isn't the only one. Methane, generated by ruminating cows and rice paddies is another; nitrous oxide, created in making fertilizer, is another; so are halocarbons, used as refrigerants. If you really want to know about how much heat we're trapping, you have to take these into account too—and that's what Deutsche Bank and its scientific advisers from MIT wanted to do.
