The distance sea turtles, whales and other wildlife might have to move to find more suitable sea temperatures can range from tens to thousands of kilometres.
Consumers are concerned about the environmental impact of meat - but reaching for fish as a 'lower emissions' alternative is an environmental catastrophe.
The oceans can generate more abundant fish populations, food for human consumption and profits for fisheries. But nations must act now to adopt fisheries management reforms that take a changing climate into account, argues KRISTIN KLEISNER

OLIVER TICKELL, the veteran environmental journalist, investigates
With the UN Ocean Conference beginning in New York next week, Elizabeth A Kirk asks: can we devise a legal system that promotes the ecological resilience of the oceans? To do so will mean placing ecosystems at the heart of decision making, over and above countries' selfish 'national interests'. It will be tough, but if we fail it's hard to see how the gamut of problems - from ocean acidification to plastic pollution and overfishing - can ever be solved.

To find out about habitats, species and ecosystems are faring, don't just look, writes Ella Browning. Listen! Many species are hard to see, but have distinct auditory signatures, and advances in electronics suggest a future of landscapes 'wired for sound' feeding data streams for ecological analysis, not to mention detecting criminal activities from 'black' fishing to illegal logging and hunting.
The world's smallest porpoise is fast heading to extinction, writes Aron White thanks to Mexico's failure to ban the use of gillnets in its range, and China's illegal imports of totoaba fish swim bladders, used in Chinese medicine. Without urgent and effective action the vaquita will soon disappear for good.
A Greenpeace investigation has exposed the massive efforts of global food and drink giant Coca Cola to defeat popular proposals to require deposits on single-use plastic bottles, writes Maeve McClenaghan.
