Could A Small Nuclear War Reverse Global Warming?

Scientists from NASA and a number of other institutions have recently been modeling the effects of a war involving a hundred Hiroshima-level bombs, or 0.03 percent of the world's current nuclear arsenal, according to National Geographic. The research suggests five million metric tons of black carbon would be swept up into the lowest portion of the atmosphere. The result, according to NASA climate models, could actually be global cooling.
