Five minutes and 27 seconds, that’s how long the candidates for President of the United States spent talking about climate change during 4.5 hours of debate time in three meetings during the 2016 General Election.

Hillary Clinton had to bring the issue up herself, in the third debate, after moderators failed to do so.

“Some country is going to be the clean energy superpower of the 21st century,” Clinton said. “Donald thinks that climate change is a hoax perpetrated by the Chinese. I think it’s real.”

“I did not. I do not say that,” Trump bristled.

He did.

Brushing Trump’s lie to the side, Clinton continued:

“Scientists say it’s real, and I think it’s important that we grip this and deal with it both at home and abroad. And here’s what we can do: We can deploy half a billion more solar panels. We can have enough clean energy to power every home. We can build a new, modern electric grid. That’s a lot of jobs.”

The national Sierra Club has now taken it upon itself to produce a series of YouTube videos calling Trump on the carpet for his climate change denialism.

Four such videos are embedded below for your viewing enjoyment.

Video 1, in which an ice sculpture of Trump’s head slowly melts to audio of his climate science denial.

Video 2, in which the Republican nominee baffles children reading his climate change Tweets.

Video 3, in which cats are “hissed” at Trump’s climate change denialism.

Video 4, in which Donald Trump was the scariest thing this Halloween.
