Such integrated multi-system models are sometimes referred to as either "earth system models" or "global climate models." Versions designed for decade to century time scale climate applications were created by Syukuro Manabe and Kirk Bryan at the Geophysical Fluid Dynamics Laboratory (GFDL) in Princeton, New Jersey. [3]
The Integrated Global System Model (IGSM) is an Integrated Assessment Model (IAM) developed by the Massachusetts Institute of Technology (MIT) Joint Program on the Science and Policy of Global Change. The IGSM couples the MIT Earth System Model (MESM), [1] an Earth system model of intermediate complexity, to the Economic Projection and Policy ...
The Community Earth System Model (CESM) is a fully coupled numerical simulation of the Earth system consisting of atmospheric, ocean, ice, land surface, carbon cycle, and other components. CESM includes a climate model providing state-of-art simulations of the Earth's past, present, and future. [ 1 ]
While the concept stems from research on the climate change, it is used to adopt a more holistic view of the observed changes. Global change refers to the changes of the Earth system, treated in its entirety with interacting physicochemical and biological components as well as the impact human societies have on the components and vice versa. [1]
Early works discussing Earth system science, like these NASA reports, generally emphasized the increasing human impacts on the Earth system as a primary driver for the need of greater integration among the life and geo-sciences, making the origins of Earth system science parallel to the beginnings of global change studies and programs.
This visualization shows early test renderings of a global computational model of Earth's atmosphere based on data from NASA's Goddard Earth Observing System Model, Version 5 (GEOS-5). Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface and ice.
The research communities represented in this partnership said in the 2001 Amsterdam Declaration on Global Change that the earth system now operates "well outside the normal state exhibited over the past 500,000 years" and that "human activity is generating change that extends well beyond natural variability—in some cases, alarmingly so—and ...
The model predicts an Equilibrium Climate Sensitivity of 1.9 °C, at the lower end of the range of GCM predictions. The model's surface temperature distribution is overly-symmetric, and does not represent the northern bias in location of the Intertropical Convergence Zone. The model generally shows lower skill at low latitudes.
