Posted on EPOCA: 26 Jan 2012 The prominent global warming event at the Paleocene-Eocene boundary (55 Ma), referred to as the Paleocene-Eocene Thermal Maximum (PETM), was characterized by rapid temperature increase and changes in the global carbon cycle in <10,000 yr, and a major extinction of benthic foraminifera.

Ocean sensors gauge pH on global scale
UC SANTA BARBARA (US) — A team of researchers has reported results from the broadest worldwide study of ocean acidification—or pH level—to date. — Posted 24 January 2012 on Futurity.Org Graduate student Emily Rivest positions a SeaFET pH sensor in a coral reef off the island of Moorea, in
Oceans could be 150% more acidic by 2100
Posted on RTCC: 23 January 2012 By Wendy Watson-Wright Wendy Watson-Wright is Executive Secretary of the Intergovernmental Oceanographic Commission at UNESCO Most of the cliffs that you see bordering the south of England and the Normandy coast were built by deposition of sediments of shellfish that have grown in steady conditions
A huge experiment
Posted on EPOCA: 23 Jan 2012 I like how Bill McKibben talks about climate change in his book “Eaarth.” Humans’ impact on the climate is like “a huge experiment,” one that has never been run before. We get to watch it play out before our very eyes, without a control, and without any true sense of
Unprecedented, man-made trends in ocean’s acidity
Posted on EPOCA: 23 Jan 2012 Nearly one-third of CO2 emissions due to human activities enters the world’s oceans. By reacting with seawater, CO2increases the water’s acidity, which may significantly reduce the calcification rate of such marine organisms as corals and mollusks. The extent to which human activities have raised the
