Even colder regions like Canada or Russia won’t escape losses, due to trade entanglements and climate unpredictability, says economist Neal.
“It’s in the extremes when the rubber hits the road,” says a researcher. Policies built on average temps miss the real-world impacts.
Redesigning models to reflect real economic risks could help nations justify aggressive emission cuts—before it’s too late, researchers urge.
