Episode 7 - Coastal and Ocean Sinks: The Changing Tide
What are Coastal and Ocean Sinks?
Project Drawdown states, “Ours is a water world. Though Earth has a land-centric name, oceans cover 71%, of its surface and make land livable. Some of the planet’s most critical processes happen where sea and air meet, as oceans absorb and redistribute heat and carbon—both rising due to the glut of emissions in the atmosphere.
Oceans have absorbed at least 90% of the excess heat generated by recent climate changes, and, since the 1980s, have taken up 20-30% of human-created carbon dioxide.7 The latter happens through the biological processes of photosynthesis and building calcium carbonate shells, and through simple chemistry, as carbon dioxide dissolves in seawater. Coastal and ocean sinks bring 17% of all heat-trapping emissions back to Earth.
While this uptake of heat and carbon has buffered the planet from more severe climate change, oceans are paying a steep price.”
Who is Dr. Patricia Yager?
Patricia Yager (Ph.D., University of Washington, 1996) is a Professor of Marine Science at the University of Georgia. Her interdisciplinary research combines oceanography, marine ecology, and bio-geo-chemistry, and concentrates on the interactions between climate and marine ecosystems.
Some of her recent projects investigate the effects of melting ice sheets on Arctic and Antarctic coastal productivity.
She was awarded a Visiting Professorship (Ciência sem Fronteiras) in Brazil, and the Antarctic Service Medal. Her research has been funded by the US National Science Foundation, NASA, DOE, NOAA, the Gordon and Betty Moore Foundation, and the Keck Foundation. She has 74 peer-reviewed publications, and has been cited nearly 4000 times.
She is the Director of the Georgia Initiative for Climate and Society at the University of Georgia, and a member of the Leadership Team for the Georgia Climate Project.
