2007 produces bad news on increase of all greenhouse gases

There is bad news all around here, with the most alarming being the sudden rise in emissions of methane, a very potent greenhouse gas (25x that of carbon dioxide). If the arctic tundra has begun to seriously outgas, the outlook is very grim.

    This will take more measurements and more time but if the methane increase is true and continues then the possibility exists that the frozen tundra is now thawing and releasing methane or even worse the methane sequestered in the ocean is being released. If true this is an irreversible change (the so-called tipping point). Recall that methane has a half-life of 7 years in the atmosphere. It ultimately gets converted to carbon dioxide.
