Shingo Watanabe,Tomohiro Hajima,Kengo Sudo,Tatsuya Nagashima,Toshihiko Takemura,Hideki Okajima,Toru Nozawa,Toru Nozawa,Hiroaki Kawase,Manabu Abe,Tokuta Yokohata,Takeshi Ise,Hisashi Sato,Etsushi Kato,Kumiko Takata,Seita Emori,Seita Emori,Michio Kawamiya +17 more
TL;DR: In this article, an earth system model (MIROC-ESM 2010) is described in terms of each model component and their interactions, and results for the CMIP5 (Coupled Model Intercomparison Project phase 5) historical simulation are presented to demonstrate the model's performance from several perspectives: atmosphere, ocean, sea-ice, land-surface, ocean and terrestrial biogeochemistry, and atmospheric chemistry and aerosols.

Carbon–Concentration and Carbon–Climate Feedbacks in CMIP5 Earth System Models
Vivek K. Arora,George J. Boer,Pierre Friedlingstein,Michael Eby,Chris D. Jones,James R. Christian,Gordon B. Bonan,Laurent Bopp,Victor Brovkin,Patricia Cadule,Tomohiro Hajima,Tatiana Ilyina,Keith Lindsay,Jerry Tjiputra,Tongwen Wu +14 more
TL;DR: In this paper, the magnitude and evolution of parameters that characterize feedbacks in the coupled carbon-climate system are compared across nine Earth system models (ESMs), based on results from biogeochemically, radiatively, and fully coupled simulations in which CO2 increases at a rate of 1% yr−1.

Twenty-First-Century Compatible CO2 Emissions and Airborne Fraction Simulated by CMIP5 Earth System Models under Four Representative Concentration Pathways
Chris D. Jones,Eddy Robertson,Vivek K. Arora,Pierre Friedlingstein,Elena Shevliakova,Laurent Bopp,Victor Brovkin,Tomohiro Hajima,Etsushi Kato,Michio Kawamiya,Spencer Liddicoat,Keith Lindsay,Christian Reick,Caroline Roelandt,Joachim Segschneider,Jerry Tjiputra +15 more
TL;DR: In this paper, the authors present results from 15 Earth system GCMs for future changes in land and ocean carbon storage and the implications for anthropogenic emissions for four future representative concentration pathways (RCPs) generated by integrated assessment models and used as scenarios by state-of-the-art climate models, enabling quantification of compatible carbon emissions for the four scenarios by complex, process-based models.
