A new study says the seas are acidifying ten times faster today than 55 million years ago when a mass extinction of marine species occurred. And, the study concludes, current changes in ocean chemistry due to the burning of fossil fuels may portend a new wave of die-offs. [...more]
Mounting evidence that human activity is changing the world’s oceans in profound and damaging ways is outlined in a new scientific discussion paper released today. [...more]
Coral reef survival is balancing on a knife edge as the combined effects of ocean acidification and ocean warming events threaten to push reefs to the brink of extinction this century, warned a meeting of leading scientists. [...more]
New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. [...more]
The Oceans are like the Goose that Laid the Golden Egg. As long as it was alive it laid a golden egg each day but then the greedy farmer decided to kill it to get all the gold inside and found nothing and the Goose laid no more golden eggs because it was dead. For centuries, the oceans have fed humankind. But in the last century, human greed has raped and pillaged oceanic eco-systems remorsefully with an ecological ignorance that is staggeringly insane.

Research presented today at the International Scientific Congress on Climate Change in Copenhagen shows that the upper range of sea level rise by 2100 could be in the range of about one meter, or possibly more. In the lower end of the spectrum it looks increasingly unlikely that sea level rise will be much less than 50 cm by 2100. This means that if emissions of greenhouse gases is not reduced quickly and substantially, even the best case scenario will hit low lying coastal areas housing one in ten humans on the planet hard.

The world is faced with a global fertilizer shortage, experts say, placing even more strain on food prices. [...more]
Increased scientific confidence that ocean observations are accurately reflecting rising global temperatures is central to new Australian research published today in the journal, Nature. [...more]
A new report released by Oceana today concludes that more than 80 percent of the world's fisheries cannot withstand increased fishing activity and only 17 percent of the world's fisheries should be considered capable of any growth in catch at all. Too Few Fish: A Regional Assessment of the World's Fisheries shows there is very little room for further expansion of global fishing efforts. [...more]
Modern agriculture and land-use practices may lead to major disruptions of the world’s water flows, with potentially sudden and dire consequences for regions least able to cope with them researchers at the Stockholm University-affiliated Stockholm Resilience Centre and McGill University have warned.
