The world’s climate goals are not sufficient. They are also unlikely to be met
We seem to be tracking for 4C of warming.<p>4C of warming would probably cause a collapse in the ability to feed the populace, and render large chunks of the world uninhabitable without active cooling, or because they&#x27;ll be underwater.<p>It&#x27;s hard to imagine how civilization survives this, without those regions that do continue to have arable land putting up walls and turrets and mowing down the streams of starving migrants.<p>At what point do you look at preppers and think &quot;honestly they might be on to something?&quot;<p>(edit: additions below)
