A fresh study on the global impact of a nuclear war has concluded that any conflict would plunge the world into darkness, cause temperatures to plummet and wipe out much of the world’s sea life.

Researchers at Louisiana State University ran multiple computer simulations to assess the impact of global and regional nuclear conflicts on the world’s oceans. They found that in all scenarios, firestorms would release soot and smoke into the upper atmosphere, blocking out the sun and forcing temperatures to fall by an average 13 degrees Fahrenheit in the first month.
