When extreme heat threatens Europe's nuclear power

Warm rivers and low water levels are forcing nuclear power plants to reduce output across Europe. Over a year, the losses are minimal, but on critical days the loss of power has consequences for grids and prices.

Ocean heatwaves are hiding months of extra warming

Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on average, potentially overlooking a major source of stress on marine ecosystems.

Satellite data reveal massive scale of routine oil pollution in oceans. See the map

Satellite data reveal nearly 1.6 million square kilometers of annual ocean oil pollution from ships and offshore platforms.

Plastic fused to coral rubble raises new concerns for ocean pollution

Plastic fused to coral rubble in Japan has been identified as “plasticoral,” raising concerns about ocean pollution and habitat degradation.

New global maps chart 40 years of ocean heat and acidification extremes

Between 2014 and 2015, a marine heatwave known as “The Blob” warmed an area of the Pacific Ocean larger than the United States and Mexico combined. The massive event fueled toxic algae blooms, collapsed fisheries, killed off millions of emaciated seabirds, sent dead fin whales (Balaenoptera physalus) and sea otters washing up on Alaska and […]

Global coral reefs get less time to recover as oceans heat up, report finds

The world’s coral reefs are losing both hard coral cover and, just as critically, the time they need to recover between increasingly frequent marine heat waves, according to the most comprehensive global reef assessment yet. Released Aug. 31 by the Global Coral Reef Monitoring Network (GCRMN), the “Status of Coral Reefs of the World: 2025” […]

Scientists say a critical Atlantic Ocean current is weakening and the effects could be global

Scientists have found strong observational evidence that a key part of the Atlantic Meridional Overturning Circulation has been weakening across a wide stretch of ocean for nearly two decades. The slowdown could eventually reshape weather patterns, rainfall, storms, winters, and coastal sea levels around the Atlantic.

Global ocean breaks records with 100 days of heat as El Niño adds new threat

For 100 consecutive days between June 2 and Sept. 10, the global ocean outside of polar regions sustained record high average sea surface temperatures, according to data from the Climate Reanalyzer, a platform overseen by the University of Maine’s Climate Change Institute in the U.S. On each of the 100 days, sea surface temperatures exceeded […]
