How Does Nuclear Winter Work?
A nuclear explosion–>nuclear explosion is like bringing a piece of the Sun –>Sun to the Earth –>Earth’s surface for a fraction of a second. Like a giant match, it causes cities and industrial areas to burn. Megacities have developed in India and Pakistan and other developing countries–>developing countries, providing tremendous amounts of fuel–>fuel for potential fires–>fires. The direct effects of the nuclear weapons, blast, radioactivity–>radioactivity, fires, and extensive pollution –>pollution, would kill millions of people, but only those near the targets. However, the fires would have another effect. The massive amounts of dark smoke from the fires would be lofted into the upper troposphere–>troposphere, 10-15 kilometers (6-9 miles–>miles) above the Earth’s surface, and then absorption of sunlight would further heat the smoke, lifting it into the stratosphere –>stratosphere, a layer where the smoke would persist for years, with no rain to wash it out.
