I read an article in the December issue of Physics Today about the effects on the climate of a nuclear war. To bottom line it a Pakistan/India nuclear exchange would put enough soot in the air to lower global temperatures by about 2 degrees C (little ice age). A large-scale exchange between Russia, China, USA, and Europe would drop the temp by 8 to 9 degrees C (full blown ice age). Reading the article made me think of the temperature vs. CO2 chart for the last 120 years. The CO2 and temperature correlate most of the time except for 1940 to 1970 or so. During that time the temperature decreases slightly while the CO2 increases. It got me wondering if above ground nuclear testing during this time frame had anything to do with this. Has any research been done about the nuclear testing age and the climate? Did the soot put in the upper atmosphere from above ground testing lower global temperature?
