Coupled simulations of the mid-Holocene and Last Glacial Maximum: new results from PMIP2
Pascale Braconnot,Bette L. Otto-Bliesner,A. Kitoh,Marie-France Loutre,Olivier Marti,Ute Merkel,Gilles Ramstein,Paul J. Valdes,Lilian A.E. Weber,Yongqiang Yu,Yan Zhao,Sandy P. Harrison,S. Joussaume,J.-Y. Peterchmitt,Ayako Abe-Ouchi,Michel Crucifix,Thierry Fichefet,Chris Hewitt,Masa Kageyama +18 more
TL;DR: In this paper, a set of coupled ocean-atmosphere simulations using state of the art climate models is now available for the Last Glacial Maximum and the mid-Holocene through the second phase of the Paleoclimate Modeling Intercomparison Project (PMIP2).
Journal ArticleDOI
The Mechanisms that Determine the Response of the Northern Hemisphere's Stationary Waves to North American Ice Sheets
TL;DR: In this paper, changes in stationary waves caused by ice sheets over North America are examined, which describe the persistent meanders in the west-east flow of the extratropical atmosphere.
Journal ArticleDOI
Response of methane emissions from wetlands to the Last Glacial Maximum and an idealized Dansgaard-Oeschger climate event: insights from two models of different complexity
Bruno Ringeval,Peter O. Hopcroft,Paul J. Valdes,P. Ciais,Gilles Ramstein,A. J. Dolman,Masa Kageyama +6 more
TL;DR: The role of different sources and sinks of CH4 in changes in atmospheric CH4 concentration during the last 100 000 yr is still not fully understood as discussed by the authors, and the uncertainties related to the parameterization of the wetland CH4 emission models relevant to these time periods by using two wetland models of different complexity (SDGVM and ORCHIDEE).
Journal ArticleDOI
Polar amplification of Pliocene climate by elevated trace gas radiative forcing
Peter O. Hopcroft,Gilles Ramstein,Thomas A. M. Pugh,Stephen J. Hunter,Fabiola Murguia-Flores,Aurélien Quiquet,Yong Sun,Ning Tan,Paul J. Valdes +8 more
TL;DR: It is concluded that natural trace gas feedbacks are critical for interpreting climate warmth during the Pliocene and potentially many other warm phases of the Cenezoic.
Journal ArticleDOI
Eocene to Oligocene terrestrial Southern Hemisphere cooling caused by declining pCO(2)
Vittoria Lauretano,Alan T. Kennedy-Asser,Vera Korasidis,Vera Korasidis,Malcolm W. Wallace,Paul J. Valdes,Daniel J. Lunt,Richard D. Pancost,B. David A. Naafs +8 more
TL;DR: In this article, the authors present a semi-continuous terrestrial temperature record spanning from the middle Eocene to the early Oligocene (~41-33 million years ago), using bacterial molecular fossils (biomarkers) preserved in a sequence of southeast Australian lignites.
