In this Climate Chat episode, Cornell climate scientist -- and returning guest -- Douglas MacMartin discusses a research paper he co-authored that says Sunlight Reflection Methods (a.k.a, solar radiation management - SRM) can stop the weakening of the Atlantic Meridional Overturning Circulation (AMOC), which is the ocean "conveyor belt" that transports warm water from the tropics to northern Europe.

Douglas MacMartin is an Associate Professor in the Sibley School of Mechanical and Aerospace Engineering at Cornell University. His research focuses on Sunlight Reflection Methods (SRM, also known as climate engineering, or climate intervention), with the aim of helping to develop the knowledge base necessary to support informed future societal decisions in this challenging and controversial field. He has published extensively on the subject, and in addition to public and academic presentations has provided briefings to the UN Environment Program and testimony to the US Congress, and was a member of the US National Academies panel that made recommendations on both research and governance in March 2021. He received his Ph.D. in Aeronautics and Astronautics from MIT in 1992; previous positions include United Technologies Research Center (1994-2000) and the California Institute of Technology (2000-2015). His research is funded by NSF and by the Cornell Atkinson Center for a Sustainable Future.
