The only living person saying much that makes sense is Greta Thunberg. Those who survive will look back on her as remarkably prescient as the rest of us failed to heed her stern admonishment while the world burned.
We were warned; we didnโt listen. Those who deserve it the least will be harmed the most.
No, I donโt know how bad itโll be in the developed world. Iโd guess only about 20% of those in the 0-16 demographic will die of direct climate-related causes (including war). Iโd guess no less than 10% will. But the tail risks are unfathomably large and old people just donโt give a fuck.
Thus, I love that old people hate Greta because she exposes their hypocrisy, their myopia, their malfeasance. They know sheโs telling the truth about what climate change will do, and to whom, and they cannot handle it. It drives them mad with rage.
