Open AccessResponse of the Greenland and Antarctic Ice Sheets to Multi-Millennial Greenhouse Warming in the Earth System Model of Intermediate Complexity LOVECLIM
Calculations were performed with the Earth system model of intermediate complexity LOVECLIM to study the response of the Greenland and Antarctic ice sheets to sustained multi-millennial greenhouse warming. Use...

Impact of Greenland and Antarctic ice sheet interactions on climate sensitivity
We use the Earth system model of intermediate complexity LOVECLIM to show the effect of coupling interactive ice sheets on the climate sensitivity of the model on a millennial time scale. We compare the respon...

Key features of the IPSL ocean atmosphere model and its sensitivity to atmospheric resolution
This paper presents the major characteristics of the Institut Pierre Simon Laplace (IPSL) coupled ocean–atmosphere general circulation model. The model components and the coupling methodology are described, as...

Impact of transient freshwater releases in the Southern Ocean on the AMOC and climate
The bipolar ocean seesaw is a process that explains the competition between deep waters formed in the North Atlantic (NA) and in the Southern Ocean (SO). In this picture, an increase in the rate of formation o...

The spatial and temporal complexity of the Holocene thermal maximum
The period of relatively warm climate from 11,000 to 5,000 years ago was marked by considerable temporal and spatial variability. Model simulations relate this complexity to the influence of the waning Laurent...

Analysis of the projected regional sea-ice changes in the Southern Ocean during the twenty-first century
Using the set of simulations performed with atmosphere-ocean general circulation models (AOGCMs) for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4), the projected regi...

Regional Response of the Climate System to Solar Forcing: The Role of the Ocean
A coupled climate model is used to explore the regional response of the climate system to solar forcing, with emphasis on the role of the ocean. It is shown that both the transient and the equilibrium response...

Evaluation of different freshwater forcing scenarios for the 8.2 ka BP event in a coupled climate model
To improve our understanding of the mechanism causing the 8.2 ka BP event, we investigated the response of ocean circulation in the ECBilt-CLIO-VECODE (Version 3) model to various freshwater fluxes into the La...

EMIC Intercomparison Project (EMIP–CO2): comparative analysis of EMIC simulations of climate, and of equilibrium and transient responses to atmospheric CO2 doubling
An intercomparison of eight EMICs (Earth system Models of Intermediate Complexity) is carried out to investigate the variation and scatter in the results of simulating (1) the climate characteristics at the pr...

Changes in European precipitation seasonality and in drought frequencies revealed by a four-century-long tree-ring isotopic record from Brittany, western France
A new paleoclimatic reconstruction for western France is obtained from tree-ring cellulose stable isotopes. Living trees from Rennes Forest and beams from two ancient buildings in Rennes city have been combine...

Surface temperature control in the North and tropical Pacific during the last glacial maximum
Based on coupled modelling evidence we argue that topographically-induced modifications of the large-scale atmospheric circulation during the last glacial maximum may have led to a reduction of the westerlies...

Exciting natural modes of variability by solar and volcanic forcing: idealized and realistic experiments
Using multi-millenium simulations performed with the three-dimensional climate model ECBILT-CLIO, we analyze how variations in the external forcing can excite low-frequency modes of climate variability. We fi...

Large sea-ice volume anomalies simulated in a coupled climate model
The processes leading to the formation of a large anomaly of sea-ice volume integrated over the Northern Hemisphere have been investigated in a coarse-resolution three-dimensional atmosphere–ocean-sea-ice mode...

A mechanism of decadal variability of the sea-ice volume in the Northern Hemisphere
A long-term simulation performed with a coarse-resolution, global, atmosphere–ocean–sea-ice model displays strong decadal variability of the sea-ice volume in the Northern Hemisphere with a significant peak at...

Earth system models of intermediate complexity: closing the gap in the spectrum of climate system models
We propose a new perspective on the hierarchy of climate models which goes beyond the "classical" climate modeling pyramid that is restricted mainly to atmospheric processes. Most notably, we introduce a new ...

The “hidden torque”: the art, for a torque, to dominate everywhere and appear in no equation
The effect of the superficial fluid layers (atmosphere and ocean) on the Earth rotation occurs by means of three torques: the pressure torque (or mountain torque) arising from a difference of pressure on the t...

A Modelling Approach to the Ross Sea Plankton Ecosystem
A conceptual and numerical model adapted to the local plankton ecosystem (ECOHYDROMVG) has been developed on the basis of the information acquired during various oceanographic cruises in the Ross Sea. The cons...

Sensitivity of a global ice–ocean model to the Bering Strait throughflow
To understand the influence of the Bering Strait on the World Ocean’s circulation, a model sensitivity analysis is conducted. The numerical experiments are carried out with a global, coupled ice–ocean model. ...
