apocalyptic scenario

If the North Atlantic Ocean’s circulation system is shut down — an apocalyptic global-warming scenario — the impact on the world’s food supplies would be disastrous, a study said Thursday.

The shutdown would cause global stocks of plankton, a vital early link in the food chain, to decline by a fifth while plankton stocks in the North Atlantic itself would shrink by more than half, it said.

“A massive decline of plankton stocks could have catastrophic effects on fisheries and human food supply in the affected regions,” warned the research, authored by Andreas Schmittner of Oregon State University.
