Even if they are not that deadly extreme heat waves could crash power grids (which is very costly due to lost productivity), kill crops and livestock, damage infrastructure, cause extreme increases in energy demand, and generally cost a shitload of money. A higher frequency of extreme cold in winter in areas that are not accustomed to it, like what recently happened in Texas, may also occur with similar consequences. I don't think climate change will be a catastrophe movie directed by JJ Abrams. I think it will be a gradual process in which we pay back the "loan" of fossil fuel use with interest. We put our civilization on a credit card without knowing the interest rate. We could have really slowed down our running up the balance in the 1970s and 1980s with nuclear power, but we didn't. We could still be doing that plus deploying a lot of renewable and storage tech that was not mature back then, but we're doing far too little of that. We are still adding to the card balance and we still don't know the interest or the repayment terms. If there are feedback loops in the climate system that we trigger, the loan could be an ARM with unscheduled interest rate increases and balloon payments. Our children get to inherit most of this bill.
