If we fail to act, we will end up with a different planet.

How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree... We don't have much time left.

It would be immoral to leave young people with a climate system spiraling out of control.

The danger is that the compromises and special interests inherent in Kyoto-style targets and cap-and-trade will be accepted because of bureaucratic momentum.

Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.

Burning all the fossil fuels will destroy the planet we know, Creation, the planet of stable climate in which civilization developed.

Injection of environmental and political perspectives in midstream of the science discussion cannot help the process of inquiry. I believe that persons with relevant scientific expertise should concentrate, with pride, on cool objective analysis, providing information to the public and decision-makers when it is found, but leaving the moral implications for later common consideration, or at most for summary inferential discussion.
