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.

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.

If we don't start thinking big about the CO2 problem, we may miss our opportunity to stop a climate runaway that will trash the habitable parts of the earth.

Trusting your energy policy to the fossil fuel lobby is like trusting your health care system to the tobacco lobby.

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

The real focus needs to be on political action to stop this runaway train, real soon.
