TL;DR: In this article, the Max-Planck-Institute Earth System Model (MPI-ESM) is used in the Coupled Model Intercomparison Project phase 5 (CMIP5) in a series of climate change experiments for either idealized CO2-only forcing or forcings based on observations and the Representative Concentration Pathway (RCP) scenarios.

TL;DR: In this article, the authors describe the mean ocean circulation and the tropical variability simulated by the Max Planck Institute for Meteorology (MPI-M) coupled atmosphere-ocean general circulation model (AOGCM).

TL;DR: In this article, the authors examined six coupled climate model simulations to determine the ocean biological response to climate warming between the beginning of the industrial revolution and 2050, and found that global warming leads to a contraction of the highly productive marginal sea ice biome by 42% in the Northern Hemisphere and 17% in Southern Hemisphere, and leads to an expansion of the low productivity permanently stratified subtropical gyre biome by 4.0% in both hemispheres.

TL;DR: In this article, the authors review the past literature on the atmospheric lifetime of fossil fuel CO2 and its impact on climate, and present initial results from a model intercomparison project on this topic.

TL;DR: The model has a climate sensitivity to a doubling of CO2 over preindustrial conditions of 2.77 K, maintaining the previously identified highly nonlinear global mean response to increasing CO2 forcing, which nonetheless can be represented by a simple two‐layer model.
