What these new findings show is that environmental damage can be more severe and last longer. Scientists calculated the damage from the preheating effect of a nuclear explosion as well as the loss of the ozone layer from the subsequent impact.
“Although we suspect that ozone will be destroyed after a nuclear war and that will result in an increase in ultraviolet light at the Earth’s surface, if there is too much smoke, it will block out ultraviolet light,” said climate scientist Alan Robock, of Rutgers University, in New Jersey.

The team analyzes the impact of war nuclear regional and global, with 5 megatonnes and 150 megatons of soot being released, respectively. A global war will result in the loss of the ozone layer by an average of 75 percent over 15 years.
Then the smoke will block the sunlight at first. In the next few years, more powerful bursts of ultraviolet light will hit the earth’s surface due to the destruction of the ozone layer. “The initial explosion, through a chemical reaction will contribute to the loss of ozone,” he said.
The terrible impact, due to nuclear radiation will make humans suffer from skin cancer, damage to agricultural land to the survival of the entire ecosystem.
“Conditions will change dramatically, and adaptations that may work at first but won’t help as temperatures reheat and UV radiation increase,” said atmospheric scientist Charles Bardeen, of the National Center for Atmospheric Research (NCAR) in Colorado.
War model nuclear as early as the 1980s predicted there would be extreme winters as smoke from nuclear explosions blocked the Sun. The current model is different in that it considers how rising temperatures as well as direct damage can impact the ozone layer through stratospheric warming.
