Who said that billions are gonna die?

Frankly, if the solution to climate change will slow economic growth, I think that the highest human cost will come from the lack of growth. To put it in clear terms: lack of growth means that a sewage system, or a hospital, don't get built. This _will_ cause victims.

Eh. While I’m optimistic that solutions will be found, in principle a shifting climate can radically alter food production. Billions could die. I don’t think they will, but in principle they could, and I lack the necessary background in agricultural science to tell what “likely” is.

I doubt that climate can shift so quickly that humans can't adapt at least their most important cultures. We're very good at this, and very quick, and we don't need to produce food anywhere near where it's consumed.

Although of course the ships that bring immense amounts of food across the globe have been built, and are operated, with fossil fuels. As is our agriculture. Again, increase the cost of the fuel that makes both possible, and people will die.
