Two months after the Paris climate-treaty negotiations concluded with fanfare, the world is figuring out it was sold a lemon.

This will provide “a turning point for the world,” according to President Obama. “Our children and grandchildren will see that we did our duty,” says UK Prime Minister David Cameron.
