President Donald Trump went on a climate change denial rant at a Turning Point USA event in Arizona on Friday, claiming, without evidence, that the Earth is actually getting cooler, despite March producing record-breaking temperatures for the United States.

“You know the green new scam, one of the greatest scams in history, remember?” Trump said. “Climate change, global warming, all of this, they actually had global warming, remember that wasn’t working because we were actually cooling as a planet. Then they had another one and another one and another one, and they were wrong, and then they just said climate change, because climate change takes care of heat, snow, whatever.”

The irony of the president’s speech taking place in Phoenix, Arizona, one of the hottest cities in the country, apparently escaped Trump — as were recent reports that showed this March was the hottest March on record and the most abnormally hot month in the 132 years of records, according to federal weather data.

These trends, however, have done little to prevent the Trump administration from gutting environmental protections and reversing efforts to reduce carbon emissions at every turn. Most recently, Trump’s EPA revoked a scientific finding that was the basis for the regulation of greenhouse gas emissions.
