After a nuclear war, humanity will face hunger for 15 years

Nuclear war will not only lead to many deaths. Smoke from 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, as a result of a regional nuclear warbetween India and Pakistan, at least five megatons of soot are produced. In the event of a global war between the US and Russia, we are talking about 150 megatons of emissions. Stratospheric heating and other factors will lead to a 15-year reduction in the ozone layer, with peak losses of 75% globally and 65% in the tropics. It will take at least ten years. This will result in more UV radiation reaching the Earth's surface. It not only threatens human health by causing cataracts and cancer. A decrease in the ozone layer and more ultraviolet radiation negatively affects agriculture and livestock. This will disrupt food supplies. Ultimately, after a nuclear war, humanity will face famine within 15 years, scientists conclude.
