When will We Observe Significant Changes in the Ocean due to Climate Change? New Study Offers Road Map

Tuesday, Aug 20, 2019

Sea temperature and ocean acidification have climbed during the last three decades to levels beyond what is expected due to natural variation alone, a new study led by AOS Postdoc Sarah Schlunegger finds. Meanwhile other impacts from climate change, such as changes in the activity of ocean microbes that regulate the Earth’s carbon and oxygen cycles, will take several more decades to a century to appear. The team of researchers included included Keith Rodgers, an AOS research oceanographer now at Pusan National University in South Korea,  Jorge Sarmiento, the George J. Magee Professor of Geoscience and Geological Engineering, Emeritus, GFDL Research Oceanographer John Dunne, and Rick Slater, a senior earth system modeler in AOS. The team also included Thomas Frölicher, a professor at the University of Bern and a former AOS postdoctoral fellow, and Masao Ishii of the Japan Meteorological Agency. The study was published recently in the journal Nature Climate Change.
