These emissions are released into the atmosphere, but much of it gets absorbed into the world's oceans. A new study, published in the Proceedings of the National Academy of Sciences , looked at prehistoric ocean sediment and found a disturbing trend. Periods of high CO2 concentrations have historically coincided with mass extinctions of marine organisms. ADVERTISEMENT British ...
