The UN estimates that by the end of the century, the average person in the world will be about 450% as rich as he or she is today ... Because of global warming, we'll be slightly less much richer. So, instead of being 450% as rich, we'll only be 434% as rich.

In the long run, we'll probably get to net zero. I struggle to believe that we won't be net zero in a couple centuries. But for 2050, or some of these states that are talking about it even before, it's just absolutely bonkers...

[William Nordhaus] estimates that if we do nothing about climate for the rest of this century, the impact will feel a little bit like we're 4% less well off than we otherwise would be.

Every dollar spent avoided about 3 cents of climate damage ... Instead of spending a dollar and doing 3 cents of good, mostly in poor countries in a long time from now, you could have just given away the dollar and done 97 cents more good.

It isn't actually a problem that's going to end humanity. Climate change is a problem, not the end of the world. If it's a problem, it's something that we should fix along with all the other problems in the world.

60% of all people now believe that it's likely global warming will lead to the end of mankind. That's terrifying, because that's not what the UN climate panel is telling us.

Every year, 300,000 moms die... from childbirth, and about 2.3 million kids die each year in the first 28 days of their life here on the planet—and most of these deaths are absolutely avoidable.

The idea that somehow a few degrees of temperature would then suddenly eradicate everything is just simply way outside of what anyone—the UN climate panel, anyone else—is really telling us.
