> The odds of the human species successful navigation of this extinction - at a civilization level - event is almost zero.

In that case, you should have no problem accepting this deal. I'll give you $10 right now. In exchange, you'll give me half of your net worth in 100 years (assume both of us will somehow be alive if civilization survives).

Humans are sub-Saharan tropical apes that somehow made it to every major landmass and climate zone in the world on stone age technology. As a species we'll be fine. Agriculture is only about 4% of the world's economic output, which gives us a lot of headroom. If it comes down it it, we triple that and probably feed the world off entirely off hydroponics in Canada and Russia.

> We had to reduce emissions 30 years ago, and simply chose not to

Greenhouse gas emissions have been rising to fuel growth that allows billions of people to achieve a quality of life that we would consider basic. Meanwhile, America's greenhouse gas emissions are below what they were 30 years ago. On a per-capita basis, they are over 25% lower.

Sure, but even Trump turns into TACO when the situation calls for it.
