Prochlorococcus populations could be cut in half in 75 years as ocean warms

(Newser) - For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic bacterium, which forms the foundation of the marine food web and helps regulate the planet's climate, will decline sharply as seas heat up. A...

For First Time on Record, Panama's Ocean Fails to Flip

Weakened trade winds disrupt vital cold-water 'upwelling' in Gulf of Panama

(Newser) - For the first time in at least four decades of record keeping, the annual upwelling event in the Gulf of Panama, on Panama's southern coast, was a no-show in 2025. This process, typically driven by northern trade winds each dry season (between December and April), brings cool, nutrient-rich...

In Norway, a World First in Carbon Storage

Oil giants team up to lock away industrial CO2 emissions in unprecedented undersea initiative

(Newser) - Norway just marked a world first. The Northern Lights consortium, backed by Equinor, Shell, and TotalEnergies, has launched a commercial carbon-storage initiative that involves injecting captured CO2 under the North Sea seabed. The operation, announced Monday, aims to help curb climate change by intercepting emissions from industrial sites across...

New Findings on Crucial Atlantic Current a Huge 'Wake-Up Call'

Scientists say collapse of AMOC currents system is no longer just a remote possibility

(Newser) - A new study suggests that the collapse of the Atlantic Meridional Overturning Circulation—a key current system that helps regulate the planet's climate—can no longer be considered a remote possibility. The AMOC, which brings warm water from the tropics to Europe and the Arctic, is currently at...
