As diplomats, activists, and journalists begin to file out of the negotiating halls of the UN Climate Change Conference in Glasgow, or COP26, there is ample evidence that the annual meeting is failing to deliver. Politicians continually declare that the world is in the midst of a climate crisis, but they have proved themselves incapable of taking the decisive action that such a crisis demands. They have fallen short of producing the $100 billion in funding for developing nations promised 11 years ago at COP16. Efforts to finalize the rules of the Paris climate accord, adopted in 2015, have also been unsuccessful.
