Antarctica’s Hidden Threat: The World’s Most Powerful Water Flow Is Accelerating

The Antarctic Circumpolar Current has accelerated before, and recent findings confirm it’s happening again.
It carries more than 100 times as much water as all the world’s rivers combined. It reaches from the ocean’s surface to its bottom, and measures as much as 2,000 kilometers across. It connects the Indian, Atlantic and Pacific oceans, and plays a key role in regulating global climate.
