Assessment of Southern Ocean water mass circulation and characteristics in CMIP5 models: Historical bias and forcing response
Jean-Baptiste Sallée,Emily Shuckburgh,Nicolas Bruneau,Andrew J. S. Meijers,Thomas J. Bracegirdle,Zhaomin Wang,Tilla Roy +6 more
TL;DR: In this article, the authors investigate the ability of the models contributing to the fifth Coupled Models Intercomparison Project (CMIP5) to represent the Southern Ocean hydrological properties and its overturning in a water mass framework.
Journal ArticleDOI
The observed evolution of oceanic pCO 2 and its drivers over the last two decades
Andrew Lenton,Nicolas Metzl,Taro Takahashi,Mareva Kuchinke,Richard J. Matear,Tilla Roy,Stewart C Sutherland,Colm Sweeney,Bronte Tilbrook +8 more
TL;DR: In this paper, the authors used a database of more than 4.4 million observations of ocean CO2 to investigate oceanic pCO2 growth rates and found that the strength of the ocean carbon sink has declined over the last two decades due to a combination of regional drivers (physical and biological).
Journal ArticleDOI

TL;DR: The Fish-MIP protocol as mentioned in this paper is designed to allow these heterogeneous models to be forced with common Earth System Model (ESM) CMIP5 outputs under prescribed scenarios for historic (from 1950s) and future (to 2100) time periods; it will be adapted to CMIP6 in future iterations.
Journal ArticleDOI
Regional Impacts of Climate Change and Atmospheric CO2 on Future Ocean Carbon Uptake: A Multimodel Linear Feedback Analysis
Tilla Roy,Laurent Bopp,Marion Gehlen,Birgit Schneider,Patricia Cadule,Thomas L. Frölicher,Thomas L. Frölicher,Thomas L. Frölicher,Joachim Segschneider,Jerry Tjiputra,Christoph Heinze,Fortunat Joos,Fortunat Joos +12 more
TL;DR: In this paper, the future oceanic CO2 uptake is simulated using an ensemble of coupled climate-carbon cycle models, driven by CO2 emissions from historical data and the Special Report on Emissions Scenarios (SRES) A2 high-emission scenario.
Journal ArticleDOI
Mid-Holocene and Last Glacial Maximum climate simulations with the IPSL model—part I: comparing IPSL_CM5A to IPSL_CM4
Masa Kageyama,Pascale Braconnot,Laurent Bopp,Arnaud Caubel,Marie-Alice Foujols,Eric Guilyardi,Myriam Khodri,James Lloyd,Fabien Lombard,Véronique Mariotti,Olivier Marti,Tilla Roy,M.-N. Woillez +12 more
TL;DR: In this paper, the authors compare the results obtained with the IPSL_CM5A model and the original IPSL-CM4 model for the pre-industrial (PI) period.
