The news last week that the Australian Newcastle city council had voted to divest from fossil fuel stocks was one of those signposts that historians will some day cite to mark the greatest economic transition in human history.
A young councillor, Declan Clausen, was able to grasp the truth that eludes the Australian federal government and indeed so many world leaders: coal—and oil and gas—are not the future and they’re barely the present. We’re suddenly and decisively, in a one-way transition to a renewable future and the only question—perhaps the most important question humans have ever faced—is whether we can make that transition fast enough to save the planet.
You can tell that coal is the past by asking any scientist with a working knowledge of the planet’s climate system. 2015 will be the hottest year in the planet’s recorded history, a landmark that comes with the requisite fire and flood. July was the hottest month ever measured on earth. New data from the most important climate scientist, NASA veteran James Hansen, concludes that on its present emissions trajectory, sea levels could rise 10 feet (three meters) this century.
