The Legal and Economic Case Against the Paris Climate Treaty

President Trump should keep his two-part campaign promise to cancel U.S. participation in the Paris Climate Agreement and stop all payments to United Nations global warming programs. The Paris Agreement is a costly and ineffectual solution to the alleged climate crisis. It is also plainly a treaty, despite President Obama’s attempt to implement it without the Senate’s advice and consent. Failure to withdraw from the agreement would entrench a constitutionally damaging precedent, set President Trump’s domestic and foreign policies in conflict, and ensure decades of diplomatic blowback.

For those and other reasons, the Paris Agreement imperils both America’s economic future and capacity for self-government.
