The British Empire has been on this path since 1918, Randers says, and other Western nations might go this route as well.

Decades of time has been squandered US president Lyndon Johnson was warned of the climate crisis by scientists when Joe Biden was still in college and yet industry denial and government inertia means the world is set for a 2.7C increase in temperature this century, even if all emissions reduction pledges are met. Read about our approach to external linking. Democratic, liberal society will fail, while stronger governments like China will be the winners.. On the ground, rising temperatures are changing the world in ways that can no longer be explained only by physics and chemistry. Homer-Dixon calls these combined forces tectonic stresses for the way in which they quietly build up and then abruptly erupt, overloading any stabilising mechanisms that otherwise keep a society in check.
