"More than 83 million Americans are expected to experience subzero temperatures this week," Kimmel pointed out. "They say it could be even colder in Chicago this week than it is in Antartica."
This bit of weather news, however, seemed to go over President Trump's head.
In the beautiful Midwest, windchill temperatures are reaching minus 60 degrees, the coldest ever recorded. In coming days, expected to get even colder. People can't last outside even for minutes. What the hell is going on with Global Waming? Please come back fast, we need you!
On Monday, Trump tweeted that the world needed to get "global waming" (spellcheck anyone?) back to help warm up the cold areas. Like the great educator he is, Kimmel brought in some kids -- Apollo, 8, and Kaitlynn, 10, -- to explain to Trump the difference between climate change and weather, how the greenhouse effect works and why this is a big environmental issue that must not be ignored.
"Just to be clear, global warming is a hoax invented by the Chinese, according to the President," Kimmel joked. "Global 'waming'is a hoax invented by George Michael and Andrew Ridgeley in 1982." (Yes, that was a Wham! joke)
"But this is a hall of fame tweet," he continued. "Is he really that ignorant that he doesn't know climate change is responsible for extreme temperatures, including cold. Is he dumb? Or is he just pretending to be dumb? I think we give him the benefit of the doubt and say he's actually dumb. If that's the case since he doesn't seem to understand climate change, we invited a couple of children who do to break it down for him."
Apollo and Kaitlynn explained the science in simple terms and even used some fun visual aids to make sure the President really understood the facts. Not only did the cute kids break it down as Kimmel promised, but they expressed how dire of a problem climate change is and how it will affect the younger generation.
"We've been adding a lot of greenhouse gases lately," Kaitlynn said. "All that extra trapped energy is already causing higher temperatures, melting ice, more extreme weather, rising sea levels, drought and a lot more things that will make Earth a pretty tough place for kids like your son Barron and me to live."
Kimmel wasn't the only late-night host that spoke about Trump's tweet. Stephen Colbert also weighed in on "global waming" during his show Tuesday night.
The CBS star presented similar facts about the extreme temperatures in the Midwest. "Wind chill temperatures are expected to reach minus 50 in Chicago and minus 50 in Minneapolis. I tell ya, I'm gonna say it. The viral marketing for 'Game of Thrones' has gone too far. We get it. Winter is coming."
Colbert pretended he didn't realize Trump's spelling error at first and had to go back. "Wait, Jim can you go back? What did that say? What the hell is going on with 'global waming?'"
"These temperatures are actually caused by global waming, sir," he continued. "Polar vortex breaks up and dips up. It's all predicted. Besides just because it's cold now, doesn't mean climate change is a myth."
