A Nuclear Winter Could Destroy Much of The World's Food Supply

It's easy to assume nuclear war only affects those close enough to see that most terrifying of clouds. In reality, the devastation could stretch around the world.

A new study shows just how badly global food production would fare under different nuclear winter scenarios.

Nuclear winter is a devastating climate effect theorized to follow large-scale nuclear conflict where blasts of nuclear weapons and the resulting firestorms inject huge amounts of soot and dust into the atmosphere. This would reduce the amount of sunlight reaching the surface for years at a time, in turn killing off many plants and animals – including those we rely on for food.

A new study, led by scientists at Pennsylvania State University in the US, simulated the effects that nuclear winter would have on global f
