Once demand for food exceeds supply all bets are off. It's hard to see how we can keep growing enough with 3 or 4 degrees of warming.

Warmer temperatures and higher CO2 levels are great for plants. The world is fully capable of growing all necessary food inside greenhouses if necessary, all it would take would be spending 25% of GDP on food rather than 10% as we do now. There will certainly be starving people in the future, but that will be a failure of capitalism not lack of capability.

I don't know, I've grown quite sceptical about what technology can achieve against this problem. I'm pretty sure increasing food spending to 25% of GDP would involve a massive societal shift. Whatever way you look at it we are in for a lot of pain.

Greenhouses have been around for 200 years.

And yes, it is a big shift with lots of pain. A massive increase in food prices would be required, which would result in riots across the third world.

Easier and cheaper to spend a trillion or five to halt the increase in carbon emissions.

We don't grow staples in greenhouses.

But we could if absolutely necessary. They'll have to do it on Mars, for instance.
