Exactly what this means for climate change, however, isn't at all certain. Eight teragrams of anything, let alone a heat-trapping greenhouse gas, sounds dangerous, but as Martin Heimann of the Max Planck Institute for Biogeochemistry in Jena, Germany, points out, the newly discovered methane leak represents a small piece of the overall global total of methane emissions - about 500 teragrams annually - from wetlands, termites and agriculture (including belching cows, rotting manure and rice paddies...
...number itself isn't what worries people, though: it's whether this newly identified methane source is part of an ominous trend. Climate scientists have long worried about the enormous amount of methane locked in Arctic permafrost, the thick layer of soil just beneath the surface that remains frozen all year. The methane was originally deposited there through decomposition of organic matter in ancient wetlands, and as long as it stays put, it can't contribute to climate change.

To that end, Republicans have purposely mischaracterized the Democratic plan from the start - as socialism, a government "takeover" of health care. It isn't, of course. In fact, the bill's cataclysmic inelegance is caused in large part by the President's promise that the current, hopelessly complicated system would remain the same for the 80% of the public that's satisfied with the insurance it has. Furthermore, the late-blooming Republican alternatives...
