We thought President Donald Trump was merely another Hitler. But, no, he’s also another Mao and another Stalin. Next he’ll be on his way to becoming Beelzebub himself, unless the climate fanatics can finally get a hold of themselves.

In one of the more maniacal rants we have seen, Rep. Sean Casten, an Illinois Democrat, swore before hundreds of millions that the administration’s dropping of the Obama-era Environmental Protection Agency’s carbon dioxide endangerment finding is an act of mass murder. Seems to be a lot to put on an administrative order that reverses the EPA’s ability to regulate CO2, which provided government with the veneer of “science” to pursue its EVs-for-all, gasoline-for-none crusade, to promote unreliable renewable energy sources, and to attack conventional energy suppliers and micromanage consumer appliance manufacturing.

“This is anti-scientific, immoral and economically irresponsible. I say this without hyperbole – when the history of this era is written, Donald Trump will have been responsible for more deaths than Stalin, Mao and Hitler combined,” Casten said last week in a particularly frothy tweeted.

That would be quite a number, maybe as high as 100 million. But even if only a little more than half that, as some have calculated, it’s still a staggering sum.

As if he didn’t expose himself enough, Casten added that he’s sure “Millions, if not billions will die if we don’t address climate change; some will survive but if rivers keep moving, coasts keep eroding, fires keep burning we will be forced to become migratory. That is a choice.”

Though it’s clearly loco, Casten’s claim is not an isolated incident. In a somewhat more measured but nonetheless irrational outburst, the author of the not-to-be-believed hockey stick chart, Michael Mann, declared that “Not since Stalin and Soviet Lysenkoism have we seen such a brazen effort to misrepresent science in service of an ideological agenda.”

Just another case of psychological projection, in which the climate zealots are accusing skeptics of using the methods they employ.

But the climatistas’ madness is more threatening than a break with reality. A few months ago, Mann wrote that if Trump didn’t comply with a federal injunction to stop the abolishment of the Education Department, “we’re in second amendment territory” He followed up by Mann-splaining that “the second amendment refers to the right of the people to rise up and defend democracy.” Anyone who argued that his statement was “a threat against Trump is very dishonest.”

The desperation is palpable.

We’ve been told that the U.S. has become “No Country for Climate Hawks,” those activists who “once perched atop” a moral high ground. These “self-anointed” high priests of the climate, says Danielle Franz of the American Conservation Coalition, “are now watching their influence dwindle.” Many are growing quiet, walking away from “aggressive environmental mandates” and retreating from “a culture war they were never equipped to win.”

This should be every reasonable person’s hope.
