Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. Picture Quebec City in Canada and London in the UK.

Addressing the Triple Planetary Crisis at Our Ocean 2025

Ocean Conservancy

As we prepare to participate in the 10 th Our Ocean Conference in Busan, Republic of Korea, from April 28-30, I like to think about this beautiful poem in a different way. Just like in the poem, the ocean remains largely undiscovered, unknown. Warmer ocean waters impact marine ecosystems, including coral reefs and fisheries.

New Research Sparks Concerns That Ocean Circulation Will Collapse

Yale E360

Scientists have long feared that warming could cause a breakdown of ocean circulation in the North Atlantic. But new research finds the real risk lies in Antarctica’s waters, where melting could disrupt currents in the next few decades, with profound impacts on global climate. Read more on E360 →

Scientists Call for More Marine Protected Areas in the Southern Ocean

Inside Climate News

By Teresa Tomassoni When Antarctic krill swarm, the semi-transparent shrimp-like crustaceans join together in the millions or trillions, forming dense coral-colored underwater clouds as they swim in sync with one another and traverse frigid ocean currents.

The Planet’s Big Blue Machine: Why the Ocean Engine Matters

Yale E360

The ocean is an enormous engine, turning heat energy into motion, says physicist Helen Czerski. But human activity is threatening that machine — depriving the seas of oxygen, increasing stratification, and potentially changing the currents that influence global weather. Read more on E360 →

As Ocean Oxygen Levels Dip, Fish Face an Uncertain Future

Yale E360

Global warming not only increases ocean temperatures, it triggers a cascade of effects that are stripping the seas of oxygen. Fish are already moving to new waters in search of oxygen, and scientists are warning of the long-term threat to fish species and marine ecosystems. Read more on E360 →

The AMOC is slowing, it’s stable, it’s slowing, no, yes, …

Real Climate

In the real ocean that is not an observed quantity. While these simulations assimilate observational data, over most of the ocean surface these are basically sea surface temperatures, but surface heat loss depends also on air temperature, wind speed, humidity, radiation and cloud cover in complex ways, all of which are not accurately known.
