The Climate Interactive, a project grew out of M.I.T.’s Sloan School of Management has a truly sophisticated and useful model on its website. It allows the user to change different variables to see what it would take to reduce greenhouse-gas emissions enough to get the world off its current impossible track (screeching toward a world something like four degrees Celsius hotter) and onto the merely miserable heading of 1.5 to two degrees Celsius envisioned in the Paris climate accords.
