A range of proxy observations have recently provided constraints on how Earth's hydrological cycle responded to early Eocene climatic changes. However, comparisons of proxy data to general circulation model (GCM) simulated hydrology are limited and i

Ocean carbon cycling during the past 130 000 years – a pilot study on inverse palaeoclimate record modelling

Autor: C. Heinze, B. A. A. Hoogakker, A. Winguth

Publikováno v: Climate of the Past, Vol 12, Iss 10, Pp 1949-1978 (2016)

What role did changes in marine carbon cycle processes and calcareous organisms play in glacial–interglacial variation in atmospheric pCO2? In order to answer this question, we explore results from an ocean biogeochemical general circulation model.

Uncertainties in the modelled CO2 threshold for Antarctic glaciation

Autor: E. Gasson, D. J. Lunt, R. DeConto, A. Goldner, M. Heinemann, M. Huber, A. N. LeGrande, D. Pollard, N. Sagoo, M. Siddall, A. Winguth, P. J. Valdes

Publikováno v: Climate of the Past, Vol 10, Iss 2, Pp 451-466 (2014)

A frequently cited atmospheric CO2 threshold for the onset of Antarctic glaciation of ~780 ppmv is based on the study of DeConto and Pollard (2003) using an ice sheet model and the GENESIS climate model. Proxy records suggest that atmospheric CO2 con

A model–data comparison for a multi-model ensemble of early Eocene atmosphere–ocean simulations: EoMIP

Autor: D. J. Lunt, T. Dunkley Jones, M. Heinemann, M. Huber, A. LeGrande, A. Winguth, C. Loptson, J. Marotzke, C. D. Roberts, J. Tindall, P. Valdes, C. Winguth

Publikováno v: Climate of the Past, Vol 8, Iss 5, Pp 1717-1736 (2012)

The early Eocene (~55 to 50 Ma) is a time period which has been explored in a large number of modelling and data studies. Here, using an ensemble of previously published model results, making up "EoMIP" – the Eocene Modelling Intercomparison Projec

Dynamics of the terrestrial biosphere, climate and atmospheric CO2 concentration during interglacials: a comparison between Eemian and Holocene

Autor: G. Schurgers, U. Mikolajewicz, M. Gröger, E. Maier-Reimer, M. Vizcaíno, A. Winguth

Publikováno v: Climate of the Past, Vol 2, Iss 2, Pp 205-220 (2006)

A complex earth system model (atmosphere and ocean general circulation models, ocean biogeochemistry and terrestrial biosphere) was used to perform transient simulations of two interglacial sections (Eemian, 128–113 ky B.P., and Holocene, 9 ky B.P.
