So as long as humans are able to grow different crops in new places, migrate by the millions without social disruption, adapt to new extremes of heat, drought, flood, and generally respond to the crisis in spectacularly improbable ways we'll be fine? Hell, we're already seeing economies on the nearing collapse due to interest rate hikes, which in turn are an idiot response to climate-change linked inflation. We're in polycrisis territory already, and while climate change isn't the whole thing, it has an enormous cascading impact on all our other problems.
