‘A kind of dark realism’: Why the climate change problem is starting to look too big to solve:

The world has waited so long that preventing disruptive climate change requires action “unprecedented in scale,” the U.N. Intergovernmental Panel on Climate Change said in an October report.

William Nordhaus, the Yale University professor who just won the Nobel Prize for his work on the economics of climate change, recently described his outlook like this: “I never use the word ‘pessimism’; I always use the word ‘realism,’ but I’d say it’s a kind of dark realism today.”

Climate scientists and policy experts realize that they walk a fine line between jolting consumers and policymakers into action and immobilizing them with paralyzing pessimism about the world’s ability to hit climate targets.
