I’m not so concerned with the fiscal costs, and I think it’s short-sighted to think of the problem as one that can be solved or ameliorated by moving dollars and percentages around. The human and environmental costs, dollars aside, are staggering and painful to think about. E.g. https://www.nytimes.com/interactive/2018/10/07/climate/ipcc-report-half-degree.html https://www.nytimes.com/interactive/2018/10/07/climate/ipcc-... 37% of world population exposed to extreme heat waves and an additional 400 million people exposed to extreme drought at a 2 degree increase. And they’ll be angry, and they’ll either find somewhere else to go en masse or will suffer even more if they can’t leave.
