Reducing ocean acidification by removing carbon dioxide: Two targets for cutting-edge research

It is now widely recognized that in order to reach the target of limiting global warming to well below 2°C above pre-industrial levels (as the objective of the Paris agreement), cutting the carbon emissions even at an unprecedented ...

Researchers create the first global assessment of cumulative human impacts to at-risk marine species over time

Despite the fact that our planet is mostly ocean and human maritime activity is more intense than it has ever been, we know remarkably little about the state of the ocean's biodiversity—the variety and balance of species ...

Seagrasses turn back the clock on ocean acidification

Spanning six years and seven seagrass meadows along the California coast, a paper published today from the University of California, Davis, is the most extensive study yet of how seagrasses can buffer ocean acidification.

Oil-eating bacteria could help to tackle spills

A team of scientists from Heriot-Watt University has created an underwater observatory in the Faroe-Shetland Channel—and found its waters are teeming with oil-eating bacteria that could help deal with future oil spills.

Changes in ocean chemistry show how sea level affects global carbon cycle

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years.

Oceans were stressed preceding abrupt, prehistoric global warming

Microscopic fossilized shells are helping geologists reconstruct Earth's climate during the Paleocene-Eocene Thermal Maximum (PETM), a period of abrupt global warming and ocean acidification that occurred 56 million years ...

Sea butterflies already struggle in acidifying Southern Ocean

The oceans are becoming more acidic because of the rapid release of carbon dioxide (CO2) caused by anthropogenic (human) activities, such as burning of fossil fuels. So far, the oceans have taken up around 30% of all anthropogenic ...

Possible irreversible changes to sub-systems prior to reaching climate change tipping points

Recently a pair of researchers with the University of Copenhagen published a paper in the Proceedings of the National Academy of Sciences describing their work looking into the possibility of changes to the Atlantic Meridional ...

Turf wars: Ocean acidification and feedback loops lock in turf algal systems

It's tough out there in the sea, as the widespread loss of complex marine communities is testament to. Researchers from Japan have discovered that ocean acidification favors degraded turf algal systems over corals and other ...
