The Paris Climate Boondoggle was never submitted to the Senate for ratification on some obscure technical grounds. It was MEANT to be a "treaty" and deserved that ratification (which I believe it would not have achieved). Instead, the Obama administration added insult to injury by submitting it to the UN, which is the primary sponsor of the delusion that mankind's CO2 emissions are having an outsized impact on the climate. Our adopting this "agreement" which has been unmet by almost all the signatories anyway (the US's declines in CO2 emissions are relatively rare among those nations, and China and India's increased emissions make whatever the US does irrelevant anyway) deserves an ignominious end. And soon.
