What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.

The climate system is being pushed hard enough that change will become obvious to the man in the street in the next decade.

Planet Earth, creation, the world in which civilization developed, the world with climate patterns that we know and stable shorelines, is in imminent peril.

Money has too big an influence on our politics in Washington and somehow we need to do something about that.

The five-year mean global temperature has been flat for the last decade

If humanity wishes to preserve a planet similar to that on which civilisation developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO₂ will need to be reduced from its current 385 ppm [parts per million] to at most 350 ppm... If the present overshoot of this target CO₂ is not brief, there is a possibility of seeding irreversible catastrophic effects.
