It is estimated that the total energy released by nuclear explosions in 20th century amounts to 600 Megatons equivalent of energy. Divided over the 510 million square meters of the earth's surface and over the two decades of peak testing, that represents 8 million of watt per square meter of power. For comparison, the 1.8 watts per square meter of CO2 Radiative forcing as of 2011 generates 29 Billion, Trillion Joules of energy over the earth's surface in a single year, or more than 10,000 times as much energy in a year that the entire combined nuclear weapons program of the world has generated.   Many Nuclear tests kick up a lot of dust which reflects sunlight thereby cooling the earth. Nuclear winter is the severe and prolonged global climatic cooling effect hypothesized to occur after widespread fire storms following a Nuclear war. The hypothesis is based on the fact that such fires can inject soot into the Stratosphere where it can block direct sunlight from reaching the
