Ocean acidification may have caused mollusc extinction sixty-six million years ago: new research

New research, led by the University of Southampton, has questioned the role played by ocean acidification, produced by the asteroid impact that killed the dinosaurs, in the extinction of ammonites and other planktonic calcifiers 66 million years ago. Ammonites, which … Continue reading

Unseen volcanoes may play role in Earth’s long-term climate: American Geophysical Union

WASHINGTON, D.C. - The intensity of volcanic activity at deeply submerged mid-ocean ridges waxes and wanes on a roughly 100,000-year cycle, according to a new study that might help explain poorly understood variations in Earth’s climate that occur on approximately … Continue reading
