Earth's strongest ocean current is speeding up and causing trouble

The Antarctic Circumpolar Current (ACC) is the strongest current on Earth that surrounds Antarctica and affects the global climate. Over the past few decades, observations show that it is accelerating. Experts weren't sure if this was the result of man-made warming or a natural pattern.

However, scientists have discovered that this oceanic powerhouse is getting stronger. What does this mean for the future of our planet?

Ocean depths

An international team of researchers embarked on a daring expedition into distant, turbulent waters. The goal was to obtain sediment cores that contain millions of years of clues about the ACC's behavior alongside changes in Earth's temperature.

Through thorough analysis, experts revealed the secrets hidden in the layers of sediment. (Sanjana Gajbhiye, more at www.earth.com)
