Overfishing is as big a threat to humanity as it is to our oceans
2016-02-15 21:53:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: There has never been a more urgent time for seafood businesses and fishing nations to make a commitment to sustainability. The worlds oceans are in trouble, with marine life plummeting and the people who are dependent on the sea for income and food left increasingly vulnerable. Data shows populations of fish and other marine vertebrates, including marine mammals, reptiles and birds have halved since 1970. Fourteen years ago when I was based with WWF in the Pacific where most of Australias...
Warmer oceans speed up Antarctic ice loss

Climate Home: European researchers have once again warned that the thinning of the Antarctic ice shelf means that the flow of glaciers on the frozen continent could accelerate, with a consequent rise in sea levels. They examine, in two separate studies, the increasingly precarious state of some of the ice shelf. When the shelf, consisting of ice floating on the ocean, melts, it makes no difference to sea levels. But the floating ice does have an effect on the land. It serves as a brake on the pace of glaciers...
How To Clean Up All That Plastic In The Oceans

National Public Radio: MICHEL MARTIN, HOST: So it's not exactly beach weather on the East Coast but in parts of the country, it is. Think about how many times you've walked along the beach and been disgusted by the mounds of plastic. You're not alone. By the year 2050, the world's oceans will have as much plastic as fish. That's according to researcher Nicholas Mallos from the nonprofit advocacy group, Ocean Conservancy. The group's work was cited recently at the Davos World Economic Forum in Switzerland. Mallos says...

Oceans Are Heating Up on the Double
2016-02-09 08:45:00| Climate Ark Climate Change & Global Warming Newsfeed
Truthdig: Ocean temperatures first collected during one of the great 19th-century voyages of exploration confirm one of the consequences of climate change: humans have managed to warm even the deepest parts of the ocean. A new study in Nature Climate Change calculates that the amount of heat absorbed by the ocean has doubled in the last 18 years. A third of this heat has collected in the depths at least 700 metres below the waves-and the same region is rapidly getting hotter. Peter Gleckler, a research...

With climate, fertilizing oceans could be zero-sum game
2016-02-01 00:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Scientists plumbing the depths of the central equatorial Pacific Ocean have found ancient sediments suggesting that one proposed way to mitigate climate warming--fertilizing the oceans with iron to produce more carbon-eating algae--may not necessarily work as envisioned. Plants need trace amounts of iron to perform photosynthesis, but certain parts of the oceans lack it, and thus algae are scarce. Recent shipboard experiments have shown that when researchers dump iron particles into such areas,...
