For 25 years the leadership of the environmental movement has told us that the solution to the climate crisis will be found almost entirely through the deployment of wind and solar power, accompanied by dramatic increases in energy efficiency.

With coal continuing to outpace every other energy source in both its use and its rate of growth; with global CO2 now past 400ppm and rising at an accelerating rate; it's time to acknowledge that these solutions alone are simply not adequate to reduce CO2 emissions quickly enough to forestall disaster.

If something is not done to dramatically change the way in which humankind produces energy, we will bequeath to our children and grandchildren a planet that is almost beyond our ability to imagine; one in which climate issues will begin to overwhelm basic social and political cohesion.
