People like to experience history, and they like the natural world.

Climate change can be profoundly disruptive of both, which leads to sadness.

"People permanently destroyed such-and-so that took hundreds/thousands/millions of years to create because they could neither wait another couple of decades for economic development nor get their act together to change their way of life in the modest ways necessary to avoid this" is not the kind of thing that looks good in retrospect.

(Note that the differential economic advantage given by burning fossil fuels is not large enough to fund dramatic public works projects in every location around the globe--and what could you do with the Maldives, anyway?)

(Note also that liking devices made from fossil fuels is a reason to not burn so many fossil fuels and use them for devices instead, not a reason to burn more!)
