Gulf Stream System at its weakest in over a millennium

In more than 1,000 years, the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has not been as weak as in recent decades. This is the result of a new study by scientists from Ireland, ...

Increasing ocean temperature threatens Greenland's ice sheet

Scientists at the University of California, Irvine and NASA's Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland's fjords. Their work is ...

As oceans warm, large fish struggle

Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment. Animals require oxygen to generate energy for movement, growth and reproduction. In a recent ...

Upper ocean temperatures hit record high in 2020

Even with the small COVID-19-related dip in global carbon emissions due to limited travel and other activities, the ocean temperatures continued a trend of breaking records in 2020. A new study, authored by 20 scientists ...

Warming and acidification form dual threat to corals

A quarter of the carbon emissions that are warming the Earth dissolve into oceans, making them more acidic. Carbon emissions and warming are also causing ocean heat waves, which in turn is bleaching the world's coral reefs.
