Post-nuclear climate change will threaten global food supplies and human health. Such conclusions were made by scientists from Rutgers University. The research results are published in the Journal of Geophysical Research – Atmospheres.
A nuclear war will not only lead to many deaths. The smoke from the resulting fires will also cause climate change for up to 15 years. It will threaten global food production and human health.
In the new study, scientists have used a modern climate model for the first time to model the effects of smoke from regional and global nuclear wars on atmospheric ozone.
For example, a regional nuclear war between India and Pakistan produces at least five megatons of soot. In the event of a global war between the United States and Russia, we are talking about 150 megatons of emissions. Stratospheric heating and other factors will reduce the ozone layer by 15 years, with peak losses of 75% in the world and 65% in the tropics. It will take at least ten years to recover. This will result in more UV radiation reaching the Earth’s surface. It not only threatens human health by causing cataracts and cancer. Reducing the ozone layer and more ultraviolet radiation negatively affects agriculture and livestock. This will disrupt food supplies. Ultimately, after a nuclear war, mankind will face famine for 15 years, scientists conclude.
