Via The Classic Liberal: Nuclear War Could Reverse Global Warming
Even a regional nuclear war could spark “unprecedented” global cooling and reduce rainfall for years, according to U.S. government computer models.
To see what climate effects a regional nuclear conflict might have, scientists from NASA and other institutions modeled a war involving a hundred Hiroshima-level bombs, each packing the equivalent of 15,000 tons of TNT—just 0.03 percent of the world’s current nuclear arsenal.
The researchers predicted the resulting fires would kick up roughly five million metric tons of black carbon into the upper part of the troposphere, the lowest layer of the Earth’s atmosphere.
In NASA climate models, this carbon then absorbed solar heat and, like a hot-air balloon, quickly lofted even higher, where the soot would take much longer to clear from the sky.
In the movie, NASA Warmal Colding alarmist James Hansen stars as General Jack D. Ripper.
