People also aren’t adaptable to the ocean rising above their nation and swallowing their land below the oceans waves. The projected effects from each degree c of change are not linear. But the IPCC report assumed linear effects - 1% gdp per degree c change, according to a talk someone else posted. That’s highly unlikely. At one projection the earth may only be able to carry 1 billion people but be projected to have a gdp only 4-8% lower than today. Any economist worth their salt should be able to tell you that losing 6/7ths of humanity is going to shrink the global economy by something way, way higher. It probably doesn’t even make quite the same relevance to discuss global gdp in that world.
