The roof of my house is covered in solar panels. When Im home, Im a pretty green fellow.

A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.

After a lifetime of nature shows and magazine photos, we arrive at the woods conditioned to expect splendor - surprised when the parking lot does not contain a snarl of animals attractively mating and killing each other.

There is an urgent need to stop subsidizing the fossil fuel industry, dramatically reduce wasted energy, and significantly shift our power supplies from oil, coal, and natural gas to wind, solar, geothermal, and other renewable energy sources.

We finally know where the red line for climate really is. After the rapid melt of arctic ice in the summer of 2007, our best scientists, led by NASA's Jim Hansen, went back to work and produced a series of papers showing that with more than 350 ppm (parts per million) of carbon dioxide in the atmosphere, we couldn't have a planet "similar to the one on which civilization developed and to which life on earth is adapted."

We spend probably more of our time than we should, just because it's close to home, worrying about the West. But it's equally important to figure out how we're going to free up the resources to let the developing world leapfrog the fossil fuel age. That's at least as mathematically important, and at least as morally crucial.

I think the world on the other side of fossil fuel is more local - the logic of sun and wind is diffuse and spread out, not concentrated like the logic of coal and oil.
