I haven't researched climate change effects; but my guess is subsistence farmers will be affected a lot. Even if climate change had equal effects to all income groups, that would affect poor people more (for a poor person losing 1$ has more effect compare to a billionare).

Farms would not stop sending food. People (HN readers are at least in the top income half (1) globally) would pay more money to buy food. Food is an essential commodity and I don't think an apocalypse is going to occur due to climate change.

tl;dr food is going to cost more and HN readers can afford that while poor people might not be able to afford it

(1) I think it's more like top 10%.

Food will cost more overall, since global arable land will reduce. But in some northern areas the growing season could actually lengthen.

I hope that the timescales are such that drastic effects won't happen this century and give humans more time to adjust/come up with technology to mitigate the effects.

2c warming by end of the century would be terrible, 10c disastrous

I think he means it won't happen quickly. If you have resources you'll be able to respond to the changing world.

Sidenote: how do you know I'm male?

I don't of course, sorry. HN has always subconsciously had a masculine tone in my mind. I'm projecting

We can just eat code, right?
