Southern Ocean Plays Dominant Role in Anthropogenic Carbon and Heat Uptake in CMIP5 Models

Tuesday, Sep 30, 2014

A new study led by AOS Collaborator Thomas Frölicher (ETH Zurich) assesses the uptake, transport and storage of anthropogenic carbon and heat in the Southern Ocean in a new set of couple carbon-climate Earth System Models conducted for the fifth Coupled Model Intercomparison Project (CMIP5).  The study shows that the Southern Ocean accounts for 43% of anthropogenic CO2 and 75% of heat uptake by the ocean over the historical period, underscoring the significant role the Southern Ocean plays in global climate.  AOS Director Jorge Sarmiento is a coauthor of the study along with GFDL Scientists, David Paynter, John Dunne, John Krasting and Mike Winton. The study was recently published in the Journal of Climate.
