TL;DR: In this article, a comparison of climate model simulations available from the PMIP1, PMIP2 and CMIP-AR4 intercomparison projects for past and future climate change simulations are examined in terms of polar temperature changes in comparison to global temperature changes and with respect to pre-industrial reference simulations.
Journal ArticleDOI
A new global biome reconstruction and data-model comparison for the Middle Pliocene
Ulrich Salzmann,Alan M. Haywood,Daniel J. Lunt,Daniel J. Lunt,Paul J. Valdes,Daniel J. Hill,Daniel J. Hill +6 more
TL;DR: In this article, a robust, comprehensive global biome reconstruction for the Middle Pliocene (c. 3.6-2.6 Ma) is presented, which is based on an internally consistent palaeobotanical data set and a coupled climate-vegetation model.
Journal ArticleDOI
Earth system sensitivity inferred from Pliocene modelling and data
Daniel J. Lunt,Daniel J. Lunt,Alan M. Haywood,Gavin A. Schmidt,Ulrich Salzmann,Ulrich Salzmann,Paul J. Valdes,Harry J. Dowsett +7 more
TL;DR: In this paper, a coupled atmosphere-ocean general circulation model was used to simulate the climate of the mid-Pliocene warm period (about three million years ago) and analyse the forcings and feedbacks that contributed to relatively warm temperatures.
Journal ArticleDOI
Modelling Pliocene warmth: contribution of atmosphere, oceans and cryosphere
Alan M. Haywood,Paul J. Valdes +1 more
TL;DR: The role of the atmosphere, oceans and cryosphere in contributing towards middle Pliocene warmth (ca 3 Ma BP) was investigated using the HadCM3 coupled ocean-atmosphere general circulation model as mentioned in this paper.
