It'll be 8 years before that brand new 15mpg truck gets off of the road. That brand new car dependent suburban neighborhood on the edge of town isn't going to be abandoned any time soon.

Don't worry. AmazonClimateSolutions or MuskClimateRepair or GatesClimateWindows will almost certainly* fix the problem for the small fee of only a few trillion dollars. They'll put some probably not toxic stuff into the atmosphere to block the sun's rays or do whatever. I'm sure everything be fine.
