During the Cold War, they were at least telling kids (at least in the USA) that the nuclear holocaust might be avoidable "if clear heads prevail," or "if we beat the Russians," or "if they back down." There was at least hope. With Climate Change, we've told two entire generations of kids that there is no hope, it's inevitable and irreversible, and that there is no way to avoid catastrophe. So is it any surprise they're all doomers when it comes to Climate? If you tell everyone that everything is hopeless, then don't be surprised when a few conclude that it really is hopeless.
