Trump doesn't "lean conservative," he's just a pathological liar with no respect for the laws of nature. Everything in nature is seen with a profit angle to the hard-line GOP. They don't grasp that life itself matters more than money.
The only environmental point Trump's got common sense on is wind power's futility.
CO2 is the main heat-trapping gas (frozen Earth w/o it) and snarky attempts to change the subject to Greta Thunberg, Al Gore, etc., won't change the physics of the situation. Real adults understand this and don't spend their time whining about critical environmental regulations with a phony "freedom" or "patriotism" angle.
