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]
The Earth has nine biophysical thresholds beyond which it cannot be pushed without disastrous consequences, the authors of a new paper in the journal Nature report. Ominously, these scientists say, we have already moved past three of these tipping points. [...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]
Overfishing and disease have decimated shellfish populations in many of the world's temperate estuarine and coastal ecosystems. Smithsonian scientists, led by Whitman Miller, ecologist at the Smithsonian Environmental Research Center in Edgewater, Md., have discovered another serious threat to these valuable filter feeders—rising levels of atmospheric carbon dioxide that contribute to the acidification of open ocean, coastal and estuarine waters. [...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.

Rising carbon dioxide in the atmosphere and the resulting effects on ocean water are making it increasingly difficult for coral reefs to grow, say scientists. A study to be published online March 13, 2009 in Geophysical Research Letters by researchers at the Carnegie Institution and the Hebrew University of Jerusalem warns that if carbon dioxide reaches double pre-industrial levels, coral reefs can be expected to not just stop growing, but also to begin dissolving all over the world.

Environmental stresses, including warmer and more acidic seawater, may be affecting the development of the ear bones in young reef fish, causing the fish to get lost at sea during a crucial stage of their development. [...more]
