A lot has changed since November 8, and more change is coming. But two things have not changed: 1) The planet is getting warmer, day by day, and 2) A carbon fee remains the most practical and effective way to restrain the thermometer. President-elect Trump’s initial personnel moves indicate that he is fully committed to eliminating as many federal regs as he can. That squelches any hopes that the Clean Power Plan, limits on methane, and higher vehicle mileage standards would help us fight climate change.

Today, the Paris Agreement will enter into force. That means that the international effort to rein in climate change will be shifting into the next gear. Day by day, companies, governments, and citizens are responding to the message that we need to reduce emissions. We are not suggesting that the world can claim victory over climate change. There is a long way to go, and there are still too many opponents. But the momentum is clear.

You may love EPA’s Clean Power Plan (CPP). Or you may hate it. Maybe you are somewhere in between those two views. But wherever you stand, it’s undeniable that the protracted and expensive fight over the CPP has become a very inefficient response to a problem that gets worse every day.

There was exciting news Labor Day Weekend about the world’s efforts to tackle climate change. In Hangzhou, China, where the G20 leaders met to work their way through a number of major issues, President Obama and China’s President Xi Jinping announced their formal ratification of December’s Paris climate accord.

Over Labor Day weekend we may hear major climate change news from Hangzhou, China. That’s where the G20 leaders will be meeting to work their way through a number of major issues. Negotiators for the United States and China have been trying to agree on terms for ratification of the Paris climate accord so that they can announce it in Hangzhou or in the days leading up to the summit.
