Deep coral reefs in a “twilight zone” in the oceans differ sharply from those near the surface, dimming hopes that they can be a refuge for marine life fleeing threats such as climate change and pollution.
Ocean acidification to hit levels not seen in 14 million years
New research led by Cardiff University has shown that under a ‘business-as-usual’ scenario of carbon dioxide (CO2) emissions, ocean acidification is likely to hit unprecedented levels.
Mediterranean is world’s most overfished sea: report
A third of the world’s commercial fish species are being caught at unsustainable levels, with overfishing at its most severe in the Mediterranean and Black Sea, according to a new report by the UN’s Food and Agriculture Organization (FAO).
Mangroves and their deforestation may emit more methane than we thought
Mangroves, the dense tangled forests that buffer land from sea in many coastal areas of the tropics, are renowned for their ability to store carbon and help fight climate change. But new research finds mangroves may emit more carbon as methane than previously estimated – emissions made even worse by …
Oxygen loss in the coastal Baltic Sea is ‘unprecedentedly severe’
The Baltic Sea is home to some of the world’s largest dead zones, areas of oxygen-starved waters where most marine animals can’t survive.
Marine plastic: Hundreds of fragments in dead seabirds
New footage of the devastating impact of plastic pollution on wildlife has been captured by a BBC team.
Barents Sea just crossed a climate tipping point — and we watched it happen
The loss of Arctic sea ice in the region has fundamentally changed the Sea, from a buffer between the Atlantic and Arctic ocean into a de facto extension of the Atlantic.
Coral reefs losing ability to keep pace with sea-level rise
Many coral reefs will be unable to keep growing fast enough to keep up with rising sea levels, leaving tropical coastlines and low-lying islands exposed to increased erosion and flooding risk, new research suggests.
Marine natural parks in Catalonia, affected by climate change
Populations of gorgonian and other benthic organisms in the Natural Park of Cap de Creus and Natural Park in Montgrí experienced a high mortality rate during 2017 due the proliferation of filament algae in the Catalan coast during 2017.
Third of Gulf’s marine life could be extinct by 2090, study finds
A third of marine species could become extinct in the Arabian Gulf by 2090 unless immediate action is taken, a study from the University of British Columbia has found, with Abu Dhabi expected to be worst hit.
Antarctica has lost 3 trillion tonnes of ice since 1992, and it’s speeding up
The most complete analysis to date measuring ice sheet changes in Antarctica reveals Earth’s southernmost continent has lost some 3 trillion tonnes of ice over the past quarter-century.
Mediterranean could become a ‘sea of plastic’, warns WWF
The Mediterranean could become a “sea of plastic”, the WWF warned on Friday in a report calling for measures to clean up one of the world’s worst affected bodies of water.
