Methinks this needs policy-level changes. There’s only so much we can do individually at this point

Immediate terms: There’s nothing that can be done to curb the heatwave IMO, but there are ways to prevent danger. Namely, AC, cooling centers, public education on preventing heat-related injuries/deaths… Maybe govts can even temporarily reduce regulations/give subsidies on split-systems to help nudge some folks, but nothing much else can be done. One pet-idea I have is cooling centers, since I know Houston (which has extreme weathers) opens cooling/warming centers when the weather is too extreme; it is a very progressive implementation that benefits those who are underprivileged

Slightly longer term: Trees/green spaces always help. Public transit systems always help. Some fairly sweeping changes in climate-related regulation (ease AC regulations, tighten car regulations, tax on pollution, etc), aimed at both reducing danger and improving the climate… or at least recuperate some “pollution tax” so the govt can use the money to plant more trees and build more trains. Also some European countries can do so much better at discouraging car use (or at least switch to EVs) given how good the train networks are; for countries without good train networks, build some

Even longer term: Massive investments in green energy; if they are investing already, invest *more. But be practical… temporary solutions like nuclear are not everyone’s cup of tea but they help with the transition. Do better on international collaboration. Find ways to discourage international trading partners from over-polluting (probably a combination of tariffs and negotiations… not my specialty).

Obligatory not an economist/political scientist, there are probably better ways to implement these than what I suggested
