It's going to be like herding stray cats, and the political leaders who can do it will be remembered as the same kind of geniuses who pulled off the American Revolution.

Anyone who would tackle our current addiction to fossil fuels is going to have to maneuver around denial.

Unless we redesign our civilization in numerous ways, all of the science in the world won't save us.

Even if we stop the growth, we'd still be adding a constant amount of fossil carbon to the atmosphere each year.

Carbon-free energy is simply something we have to do. The time for talk is past. If we turn around net carbon emissions by 2020 rather than 2040, we get another 2° of fever rather than 3° - and that's a big difference.

You can always spot the pioneers by the arrows in their backs.

Perhaps we should put up posters in such places reminding people that where they stand was underwater the last time that the Earth ran a 3°F fever.
