The U.N. hekd an unusually uplifting dinner last night that featured heavyweights Ban Ki Moon, Al Gore and Sen. John Kerry, each of whom laid out their vision for a deal at COP-15 and a climate bill next spring in the U.S. They are convinced that we will have an international agreement and an American bill, both of which can lead to the innovations we need to change the chemistry of the atmosphere that we have tampered with so severely.
