In a just world the United States would pay back the $4 trillion dollars it owes, according to new research, for trashing the climate.
Global warming wasn’t created equal. Rich, industrialized nations have contributed the lion’s share of the carbon pollution to our currently-unfolding catastrophe—the more CO2 in the atmosphere, the hotter it gets, of course—while smaller, poorer, and more agrarian countries are little to blame. The subsequent warming from our carbon-stuffed skies will, naturally, impact everyone, often hitting the poorer countries harder. So, since the rich fueled the crisis that’s about to soak the poor, they might help chip in to soften the blow.
