Integrating oceans into climate policy: Any green new deal needs a splash of blue

Conservation Letters, Volume 13, Issue 5, September/October 2020., 2020
Abstract Recent warnings from scientists suggest there is limited time to enact policies to avert wide‐ranging ecological and social damage from climate change. In the United States, discussions about comprehensive national policies to avert climate change have begun, with “Green New Deal” proposals and climate plans put forth by members of Congress ...
