Seriously, read this:
… within several decades after Trump’s presidency has ended, the looming effects of ecological disaster due to human-caused climate change—which Trump not only denies but is doing so much to accelerate—will be inescapable. Desertification of continental interiors, flooding of populous coastal areas, and increased frequency and intensity of extreme weather events, with concomitant shortages of fresh water and food, will set in motion both population flight and conflicts over scarce resources that dwarf the current fate of Central Africa and Syria. No wall will be high enough to shelter the US from these events. Trump is not Hitler and Trumpism is not Nazism, but regardless of how the Trump presidency concludes, this is a story unlikely to have a happy ending.
