The last two years in American politics have spelled trouble for the global climate, thanks largely to the Trump administration. And the next two years probably won’t be much better, given the results of Tuesday’s midterm elections.

Voters failed to pass a historic ballot initiative in Washington state to create the first-ever carbon tax in the United States. They rejected a ballot measure to increase renewable energy in Arizona, and to limit fracking in Colorado. Some of Congress’ most outspoken climate deniers held onto their seats. Several candidates who ran on explicitly pro-climate agendas lost.

Democrats did not quite get the blue wave they wanted, but it was even worse for environmentalists. There was no green wave whatsoever. That’s partially because of record political spending by the fossil fuel industry to oppose pro-climate initiatives, but also because of the Democratic Party’s failure as a whole to draw much attention to the issue.

The midterm elections were always going to be consequential for climate change. The world’s governments only have about twelve years to implement policies that can limit global warming to 1.5 degrees Celsius. That’s the point at which catastrophic impacts begin, according to a recent report from an international consortium of scientists.

The U.S., as the largest historical emitter of greenhouse gases, is essential to achieving that target. But for the last two years, the U.S. government has been ignoring the need to reduce emissions—and in many cases, actively working against it. Along with withdrawing from the Paris climate agreement, President Donald Trump has been attempting to repeal and weaken existing climate regulation, with the support of the Republican-controlled Congress.
