These train-track equations, it turns out, are selections from the scientific pursuits of Syukuro Manube, a pioneer in developing computer models for the Earth's climate as it undergoes changes wrought by mankind. In a 1967 paper, Manube and Richard Wetherald presented a model of the interacting atmosphere-ocean-land systems that predicted today's degenerating state of affairs with a remarkable degree of accuracy. Genius graces the walls.
Why? What's wrong with us? It's safe to say that we're screwing up for reasons related to human nature and our path-dependent institutions, but the Paris treaty itself is flawed for being entirely unenforceable. It operates like a team of basketball players who huddle up, stick their hands together in a messy mass and yell "Hustle!" Then the players jog around the court like it's Sunday afternoon on the Island of La Grande Jatte and the coach isn't allowed to take them out of the game.

We'll always have Paris.
