Journal ArticleDOI
Simulating the Last Interglacial Greenland stable water isotope peak: The role of Arctic sea ice changes
Irene Malmierca-Vallet,Louise C. Sime,Julia Tindall,Emilie Capron,Emilie Capron,Paul J. Valdes,Bo Møllesøe Vinther,Max D. Holloway +7 more
TL;DR: In this article, the isotope-enabled HadCM3 (UK Met Office coupled atmosphere-ocean general circulation model) was used to investigate whether a retreat of Northern Hemisphere sea ice was responsible for this model-data disagreement.
Journal ArticleDOI
New insights into the thermal regime and hydrodynamics of the early Late Cretaceous Arctic
Robert A. Spicer,Robert A. Spicer,Paul J. Valdes,Alice C. Hughes,Jian Yang,Teresa E.V. Spicer,Alexei B. Herman,Alexander Farnsworth +7 more
TL;DR: In this paper, a new high spatial resolution (∼1 km) WorldClim2 calibration of the Climate Leaf Analysis Multivariate Program (CLAMP) yields results similar to, but often slightly warmer than, previous analyses, but also provides more detailed insights into the hydrological regime through the return of annual and seasonal vapour pressure deficit (VPD), potential evapotranspiration (PET) estimates and soil moisture, as well as new thermal overviews through measures of thermicity and growing degree days.
Book ChapterDOI
Global terrestrial productivity in the Mid-Cretaceous (100 Ma): Model simulations and data
Journal ArticleDOI
The Role of CO2 and Dynamic Vegetation on the Impact of Temperate Land-Use Change in the HadCM3 Coupled Climate Model
TL;DR: In this article, the authors used the HadCM3 coupled climate model under a range of equilibrium forcings to show that the impact of LUC declines under increasing atmospheric CO2, specifically in temperate and boreal regions.
Journal ArticleDOI
Green Mountains and White Plains: The Effect of Northern Hemisphere Ice Sheets on the Global Energy Budget
TL;DR: In this article, the changes in the global energy budget in response to imposing an ice sheet's topography, albedo, or topography and albedos combined are examined.
