Secretary of State John Kerry sat down with MSNBC’s Chris Hayes recently to discuss, among other things, what a Donald Trump presidency would mean for climate change. Kerry didn’t mince words.

Trump, who doesn’t accept that climate change is happening, has threatened to rip up the Paris Agreement, the climate deal reached by nearly 200 nations last December to reduce greenhouse gas emissions.

“Ripping up the climate agreement that was reached in Paris would be reckless, counterproductive, self-destructive,” Kerry told Hayes. “It would be an act of extraordinary danger to our country because of the path it would put us on both in terms of our global leadership on the issue as well as the actual policies we need to implement, and it would, in the end, be an act of ignorance — of utter, unbelievable, contemptuous ignorance — to get rid of something that the world has worked for since 1992 in Rio.”

Allow us to translate that diplomat-speak for you: “It would be nuts! You hear me? Completely fucking nuts!”
