Abstract:: What is the uncertainty of climate-carbon cycle projections in response to anthropogenic greenhouse gas emissions and how can we reduce this uncertainty? We address this question by quantifying the ability of available ocean tracer observations to constrain the values of diapycnal diffusivity in the pelagic ocean (Kv), a key uncertain...

Full Text:: uncertainty of ocean diapycnal 3 mixing and climate–carbon cycle projections 4 Andreas Schmittner,1 Nathan M

Creator:: Schmittner, Andreas, Tonkonojenkov, Roman, Urban, Nathan M., Goes, Marlos, Haran, Murali, and Keller, Klaus
Abstract:: Current projections of the oceanic response to anthropogenic climate forcings are uncertain. Two key sources of these uncertainties are (1) structural errors in current Earth system models and (2) imperfect knowledge of model parameters. Ocean tracer observations have the potential to reduce these uncertainties. Previous studies typically consider each tracer...

Creator:: Schmittner, Andreas, Urban, Nathan M., Shakun, Jeremy D., Mahowald, Natalie M., Clark, Peter U., Bartlein, Patrick J., Mix, Alan C., and Rosell-Mele, Antoni
Abstract:: Assessing impacts of future anthropogenic carbon emissions is currently impeded by uncertainties in our knowledge of equilibrium climate sensitivity to atmospheric carbon dioxide doubling. Previous studies suggest 3 K as best estimate, 2–4.5 K as the 66% probability range, and non-zero probabilities for much higher values, the latter implying a...

Creator:: Zickfeld, Kirsten, Eby, Michael, Matthews, H. Damon, Schmittner, Andreas, and Weaver, Andrew J.
Abstract:: Coupled climate–carbon models have shown the potential for large feedbacks between climate change, atmospheric CO₂ concentrations, and global carbon sinks. Standard metrics of this feedback assume that the response of land and ocean carbon uptake to CO₂ (concentration–carbon cycle feedback) and climate change (climate–carbon cycle feedback) combine linearly. This study...
