The leader of the free world cannot, must not, be a climate science denier. Trump's mantra? Burn baby burn!
OF COURSE he denies science...too stupid to understand it and too greedy to pay scientists to work in it, he just fritters it all away with sarcasm and hopes his minions will believe what he says.
Or perhaps, even worse, he does understand the gravity of the situation but cynically panders to his base purely for personal/political gain.
