We've solved plenty of problems at scale; think ozone layer depletion being reduced.
The problem with climate change is that it is really expensive to fix with highly uncertain costs to do so.
- jellicle 7y agoClimate action has a net negative cost; spending $10 will get you more than $10 of benefit for almost any intervention you'd care to name. So it's not expensive in any long-run calculation, only the short-run.
- usaar333 7y agoCertainly high ROI ones (say not building new coal power plants), but definitely not the lower ROI interventions. Nor is cost net negative if you use high discount rates and try lower co2 targets (e.g. 3 degrees warming by 2100 is much more likely to have positive ROI than say holding 2 degrees). Huge controversy around protecting against lower probability, highly destructive scenarios. Point is there's lots of controversy here. https://en.m.wikipedia.org/wiki/Economics_of_climate_change_mitigation https://en.m.wikipedia.org/wiki/Economics_of_climate_change_...
