You DO realize that there are already hundreds of thousands, if not MILLIONS people being displaced by climate change, right? This is not some abstract idea. It’s happening TODAY, as we speak. It’s having a real world impact on real people.
This isn’t about some rich person’s bottom line. It’s about humanity refusing to make the necessary changes to stave off the worst case scenario, so that a few people can get even richer before the planet is fucking inhabitable. If Harvard, which has a huge endowment to invest, is willing to do something to help disinvest from fossil fuels, that’s great. It’s a shame that as @MerelyGifted noted, it took them a year to do the right thing.
