Greenhouse gases that drive man-made climate change are also dangerously changing ocean chemistry, likely faster than at any other time in the past 300 million years, according to research coordinated between New York state and the United Kingdom.
The change — known as ocean acidification — is associated with several massive extinctions of marine life in that period of Earth's history, and now presents a growing threat, said study lead author Barbel Honisch, a paleoceanographer at Columbia University's Lamont-Doherty Earth Observatory.
Located in Rockland County on the Hudson River, where the ocean tides stretch upriver to Troy, the observatory was joined by the University of Bristol in southern England in the report, which examined several hundred independent studies from around the world done over the last two decades.
The work is the first of its kind to survey the geologic record of the oceans for such a vast time period. Read more:
