Existing policies aimed at arresting the pace of global warming aren’t working. China, the world’s largest emitter, has reiterated its refusal to reduce carbon emissions or curtail financing of new coal-fired generating stations at home and abroad. Japan and Australia have told the International Energy Agency that they have no intention of taking the steps the IEA deems necessary to reach the goal of zero net emissions by 2050.

Add to these Russia, Saudi Arabia, and India, and it becomes clear there will be no voluntary international consensus to reach net-zero emissions by 2050 — or ever. The game that has been played since delegates of some 200 nations inked the 2015 Paris Agreement is over. Game, set, and match to the emitting team. Paris has fallen.
