Ocean deoxygenation from volcanism during the Mesozoic Era was much more rapid than previously thought, with CO2-induced environmental warming creating ocean “dead zones” over timescales of only tens of thousands of years. The research from the University of British Columbia (UBC) and University of Hong Kong (HKU) Earth scientists paints a new picture of severe ...
