It doesn't matter. He's bad at shilling.
The point isn't if the globe is getting warmer or not, what these carbon tax pushing, car fun hating, white genociding shills want to convince people of, is that this warming is man made or not.
Ten years ago it was common knowledge that millions of years ago fern grew on even the most northern parts of greenland, and that dinosaurs roamed it (same with antarctica); also that 20k years ago the ice caps covered a much larger area.
So they are working on making us forget all this, replace this knowledge with this human made warming crap, just because they would find it hard to convince people that Donald Trump travelled back in time to sell combustion engines to the Flintstones. Fucking hate these kike vermin.
