Computer simulations have revealed what will become of the Earth after a nuclear war

Until now, we knew about the consequences of a nuclear war mainly from science fiction films and novels. A team of four American environmental scientists decided to simulate on a computer the consequences of a local nuclear conflict on the example of India and Pakistan, which recently acquired nuclear weapons.

Scientists have suggested that the opposing sides used 100 nuclear warheads against each other, each of which is equal in power to the charge of the bomb dropped on Hiroshima. Here's what happened in the end:

  • 5 megatons of black carbon will be emitted into the atmosphere;
  • In a year, the average temperature on the planet will drop by 16.7 ° C. Even after 20 years, the "pre-war" heat will not be restored;
  • As the temperature drops, the amount of precipitation will decrease. After 26 years, the Earth will still receive less than 4.5% of precipitation from the pre-war level;
  • Within 2-6 years after the nuclear conflict, the vegetation of agricultural crops will be reduced by 10-40 days;
  • Nuclear explosions will lead to chemical reactions in the atmosphere that will reduce the Earth's ozone layer by about a quarter over 5 years;
  • As a consequence, there is a sharp increase in skin cancer, sunburn, decreased plant growth and destabilization of DNA in some crops;
  • Widespread crop failure will lead to widespread famine affecting up to 2 billion people.

This is the result of using only 100 small nuclear bombs.
