It's a riot that at the top of this (otherwise sensible) article is a Doomsday Clock announcing that humankind is "5 Minutes to Midnight." That's closer than it was for much of the cold war! Sure there's a pretty good chance some third-world nutjob will get his hands on a tiny nuke soon, and yes, over the next CENTURY, several million people will need to migrate inland to avoid flooding, and probably learn to farm different crops.
But Doomsday? In five minutes?
That clock is, literally, the single most needlessly alarmist message coming from "experts" since... Ever.
