In the last week, Republican presidential nominee Donald Trump has repeatedly vowed to zero out all federal spending on clean energy research and development. And the plan he released would also zero out all other spending on anything to do with climate change, including the government’s entire climate science effort.

You may have missed this bombshell because team Trump did not spell out these cuts overtly. In a campaign where the media has “utterly failed to convey the policy stakes in the election,” as Vox’s Matt Yglesias explained recently, it appears only Bloomberg BNA bothered to follow up with the campaign to get at the truth of Trump’s radical proposal.

Polling guru Nate Silver of fivethirtyeight.com fame gives Trump a one in three chance of becoming president. So I agree with Yglesias that we ought to seriously look at the implications of Trump’s proposals — especially since if Trump wins, he’s all but certain to have a GOP-controlled Congress to back him.

Trump’s newest energy plan

In announcing his “New Deal For Black America” on October 26, Trump promised:

“I will also cancel all wasteful climate change spending from Obama-Clinton, including all global warming payments to the United Nations. These steps will save $100 billion over 8 years, and this money will be used to help rebuild the vital infrastructure, including water systems, in America’s inner cities.”

I’ll bet you never even knew the U.S. budgets $12.5 billion a year ($100 billion over eight years) on climate change, let alone wastefully.

Fortunately for us, BNA Bloomberg queried the campaign on where that $100 billion figure came from. You will not be shocked to learn the “Trump campaign did not give a specific tally to account for the $100 billion total in response.” And the news release announcing his New Deal contains no specifics.

But Bloomberg does have a money quote, so to speak:

“The e-mail said the estimate was based on a Congressional Research Service report in 2013 that looked at federal climate change funding from fiscal year 2008 to the administration’s budget request for FY 2014.”

And here is the money chart from the 2013 CRS report, “Federal Climate Change Funding from FY2008 to FY2014”:
