Yes. Agricultural collapse, rather than heatstroke, is what'll start killing people if we see WBTs in the low 30s. The tropics don't usually get as hot as the worst days in the midlatitude zones; what defines the tropical zone is temperature consistency. This means that many species won't adapt to serious climate change if it happens so rapidly, but it also means we can expect labor productivity to drop by 50% or more, because if tropical locations start posting 31-32 WBTs, they won't be doing it once per year (as you see on the hottest days in the midlatitudes) but hundreds of days per year. If corporate workers become 50% less productive, that just means fewer passive-aggressive emails get sent; but if global farm labor becomes 50% less productive, we're in a shitload of trouble.
