Collaborative study of GENIEfy Earth System Models using scripted database workflows in a Grid-enabled PSE
A.R. Price,Zhuoan Jiao,Ivan Voutchkov,Timothy M. Lenton,G. Williams,Daniel J. Lunt,Robert Marsh,Paul J. Valdes,Simon J. Cox +8 more
TL;DR: This paper presents for the first time, the application of the non-dominated sorting genetic algorithm (NSGA-II) to perform a multi-objective tuning of a 3D atmosphere model, providing evidence for bi-stability in the Atlantic Meridional Overturning Circulation.
The Eocene-Oligocene boundary and the Antarctic Circumpolar Current
TL;DR: In this article, the Hadley Centre Coupled Climate Model version 3 was used to perform a suite of Oligocene experiments to demonstrate that whilst an Antarctic Circumpolar Current (ACC) does initiate following the opening of the Drake Passage, its volume transport is weak compared to modern.
Journal ArticleDOI

Davide Foffa,Emma M. Dunne,Sterling J. Nesbitt,Richard J. Butler,Nicholas C. Fraser,Stephen L. Brusatte,Alexander Farnsworth,Daniel J. Lunt,Paul J. Valdes,Stig A. Walsh,Paul M. Barrett +10 more
TL;DR: Scleromochlus taylori, a tiny reptile from the early Late Triassic of Scotland discovered over a century ago, was hypothesized to be a key taxon closely related to pterosaurs as mentioned in this paper .
Posted ContentDOI
Simulating the Climate Response to Atmospheric Oxygen Variability in the Phanerozoic
David C. Wade,Luke Abraham,Alexander Farnsworth,Paul J. Valdes,Fran Bragg,Alexander T. Archibald +5 more
TL;DR: In this paper, the authors present the first 3D numerical model simulations to investigate the climate impacts of changes in O2 during different climate states using the HadGEM3-AO and HadCM3-BL models.
Journal ArticleDOI
Seasonal temperatures in West Antarctica during the Holocene
Tyler R. Jones,Kurt M. Cuffey,William H. G. Roberts,Bradley R. Markle,Eric J. Steig,Craig Stevens,Paul J. Valdes,Taylor J. Fudge,Michael Sigl,A. M. Hughes,Valerie Morris,Bruce H. Vaughn,Joshua Garland,Bo Møllesøe Vinther,Kevin S. Rozmiarek,Chloe Brashear,James W. C. White +16 more
TL;DR: In this article , the authors analyse a continuous record of water-isotope ratios from the West Antarctic Ice Sheet Divide ice core to reveal summer and winter temperature changes through the last 11,000 years.
