Solution to corrosive ocean mystery points to future climate

摘要

Researchers have discovered how an abrupt global warming event triggered a highly corrosive deep-water current to flow through the North Atlantic Ocean 55 million years ago. The findings, published in Nature Geoscience (doi: 10.1038/ngeo2430), solve a long-running scientific mystery that also has profound implications for the sensitivity of our current climate to carbon dioxide emissions.
