Let’s face it: The Bush Administration has made a mess of things. It is now clear, if it hasn’t been all along, that by the time George Bush leaves office, the White House will have wasted eight years of leadership on the Mother of All Issues.

If those eight years are a profound disappointment looking backward, then they are a profound tragedy looking forward. The head of the IPCC is spreading the message that the world community has seven short years to act decisively to curb greenhouse gas emissions. Dr. John Holdren is among the prestigious U.S. scientists who now say more openly that the affects of climate change already are upon us. Dr. Jim Hansen now estimates that atmospheric concentrations of carbon must level off at 350 ppm, nearly 30 percent lower than everyone thought was needed to keep climate change at "safe" levels. Anyone who’s paying attention sees that the impacts of global warming are occurring much faster than predicted.

If this year’s weather extremes are a sample of climate change, how much worse will they be 10 years, 20 years or 30 years from now, as today’s rising and accumulating emissions take their toll?
