Scientists call for no-fishing zone in Arctic


Thousands of scientists from 67 countries have called for an international agreement to close the Arctic high seas to commercial fishing until research reveals more about the freshly exposed waters.

Recent Arctic sea-ice retreat during the summer months has opened up some of the waters that fall outside of the exclusive economic zones of the nations that circle the polar ocean. In all, more than 2.8 million square kilometres … Read the rest

Regime Change: Q&A with John Smol


A freshwater ecologist at Queen’s University in Kingston, Ontario, Canada, Smol studies lake sediments to understand climatic and environmental change. Nature Outlook asks him to share his experience.

What can we learn from lake sediments?
One of the biggest challenges in environmental science is the lack of long-term data, so we have to use indirect proxies. All over the planet, lakes act as passive samplers of the environment, recording … Read the rest

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
