A new politics can spark the clean-energy revolution that will serve as a foundation for a new era of human prosperity, protect the world's forests, stabilize the climate, and preserve the diversity of life on the planet.

The most rational defender of nature is driven by a passion for wildness that cannot be explained by an appeal to logic.

Electing clean-energy leaders into the Senate, the House, and the Oval Office - and getting it done in the next few years - is the only real solution to climate stabilization at acceptable levels.

It is time to start going door to door and convincing our neighbours to vote for a clean-energy future.

The Arctic is the planet's air conditioner and it's starting to break down.

It will be politics that determines the material welfare of future generations: the pace at which we advance toward "our destination of economic bliss," andnperhaps, whether we continue to advance at all.

The human response it calls for is truly heroic, requiring nothing short of rewiring the entire planet with a new generation of clean-energy technologies - and doing that very soon... Are we, as a species, capable of that kind of deliberate global response?
