His idea of it being "not insurmountable" is essentially us not starving to death in a mass scale.

I care, in my comfortable life as an office worker, about the fact that chocolate, coffee, and wine will become luxuries as yields and quality drastically drop off.

I care about the fact that many places I visit frequently will need A/C to be _survivable_.

Those are not civilization-ending events but the hubris you need to have to just hand-wave this away are beyond my understanding.
