From: Modeling in Earth system science up to and beyond IPCC AR5

 

EMICs (8 models)

CMIP5 ESMs (15 models for ECS, 9 models for others)

ECS (K)

3.04 ± 0.67

3.37 ± 0.83

β L (PgC/ppm)

0.69 ± 0.31

0.92 ± 0.44

β o (PgC/ppm)

0.93 ± 0.19

0.80 ± 0.07

  1. These parameters were estimated by EMICs and ESMs. Variables were obtained from Eby et al. ([2013]) for EMICs and from Andrews et al. ([2012]) and Arora et al. ([2013]) for ESMs. L, land; O, ocean.
