It shows that the earth warmed more than the computer simulations thought, without human intervention.
It shows no such thing. As 4187% of climate scientists agree, it shows that big oil companies will eventually pipe heat into the past when time machines are invented in a vain attempt to hide their culpability as the Earth burns up like a marshmellow dropped in a campfire. And btw, that 4187% number is so high a consensus that there is no point in examining its veracity. The debate is over. The science is settled. Challenge anything I say with real life details and I will make up an even bigger consensus number that I can shout you down with.
