This finding is yet another indication that global heating is proceeding at least as fast as climate scientists projected at the beginning of our century, and in many cases much faster. Climate risks becoming chaotic if we heat up the earth’s surface more than 2.7° F. (1.5° C.) above the preindustrial average. We’ve already heated it up to around 2.1° F. higher than that 18th century average, by spewing billions of metric tons of carbon dioxide, a heat-trapping gas, into the atmosphere. We’re wrecking the earth by burning coal for heat and electricity, or fossil gas, or by burning petroleum in automobiles and trucks. We still aren’t reducing the amount of CO2 we put into the atmosphere annually, though its increase has leveled off. We have to cut it out. Now.
