  1. C4MIP, Coupled Climate Carbon Cycle Model Intercomparison Project.
  2. Parameters describing chemical and climate feedback to land and ocean sinks climate sensitivity (α), land sink sensitivity to carbon (βL) and climate (γL) and ocean sensitivity to carbon (βO) and climate (γO). All parameters are calculated as in C4MIP4. This meta-analysis is also the source of the averages in the second row, which report directly comparable feedback parameters for an ensemble of 11 similar models.
