Despite intense climate worries, electorates have been unwilling to spend the trillions needed to cut emissions dramatically. That is why climate campaigners have increasingly pursued a new strategy: forcing climate policy through courts. Across the world, the UN now counts at least 1,550 such climate cases in 38 countries and more than a thousand just in the U.S., often filed by young people invoking a fear for their future. Unfortunately, such cases undermine democracy, harm the poor and sidetrack us from smarter ways to fix the climate.
