Donald Trump met with advisors and Cabinet members Tuesday to decide whether to take the U.S. out of the Paris Climate Treaty — a deal that was sold to the public based on the idea it would lessen the threat of global warming. In fact, it’s really nothing more than an attempt by other, less-well-to-do nations to shame the U.S. into dismantling its economy and its standard of living.

Walking away from the sham treaty shouldn’t be a hard decision.

Trump promised several times to exit the Paris treaty during his presidential campaign. He should keep his promise.

It was a bad idea from the beginning, a bogus climate deal intended to take billions of dollars from wealthy nations and give them to developing nations, many of which lack even basic political or human rights.

President Obama agreed to the deal, but never presented it as a treaty to the Senate for ratification, as the law requires. Instead, in 2016 he pretended it wasn’t a treaty and started using executive orders to put the agreement into effect unilaterally.

This wasn’t just some political maneuver. It was a brazen attempt by Obama to put the U.S. economy under the control of other nations without the input of U.S. citizens and their representatives in Congress — a clear violation of our Constitution.

The U.S. should walk away — quickly, and without hesitation — from this awful climate deal, which would sock Americans with hundreds of billions of dollars in lost output and millions of lost jobs in exchange for minuscule, impossible-to-measure cuts in carbon-dioxide output.

No doubt, Trump will get an earful from climate-change zealots about being a science “denier.” But those who say such foolish things are not speaking in the interest of science; they’re mainly media types and hyper-politicized scientists who are hooked on government funding for their global warming crusade.

The 184-nation Paris deal was ridiculous from the very beginning.

Instead of CO2 cuts that would lead to a 2-degree-centigrade rise in expected temperatures from preindustrial levels during this century, radical environmental groups pushed the assembled
