Acidic oceans threaten fish

Stocks could suffer as seas soak up more carbon dioxide. 

Ocean acidification looks likely to damage crucial fish stocks. Two studies published today in Nature Climate Change reveal that high carbon dioxide concentrations can cause death and organ damage in very young fish.

The work challenges the belief that fish, unlike organisms with shells or exoskeletons made of calcium carbonate, will be safe as marine CO2 levels rise.

Fish could … Read the rest

Arctic Ocean full up with carbon dioxide

Loss of sea ice is unlikely to enable Arctic waters to mop up more carbon dioxide from the air.

As climate scientists watched the Arctic’s sea-ice cover shrink year after year, they thought there might be a silver lining: an ice-free Arctic Ocean could soak up large amounts of CO2 from the atmosphere, slowing down the accumulation of greenhouse gases and climate change.

But research published in Science today … Read the rest
