The Scientific Basis. Such models have developed progressively from the physical climate models first created in the 1960s and 1970s.

For example, different plants absorb carbon dioxide at different rates. Meteorol. Res. This study was funded by the Helmholtz Association and by the Initiative and Networking Fund of the Helmholtz Association through the project Advanced Earth System Modelling Capacity (ESM). Earth System models (ESMs) are global climate models with the added capability to explicitly represent biogeochemical processes that interact with the physical climate and so alter its response to forcing such as that associated with humancaused emissions of greenhouse gases. The atmosphere including clouds, aerosols, and gases. The overarching goal of BioEarth is to improve understanding of the interactions between coupled C:N:H 2 O dynamics and human actions at regional and decadal scales under global change to 1) better understand the role that resource management actions have in impacting earth system dynamics, and 2) inform resource managers about the consequences of their decisions on the earth . Ocean circulation, ice shelf, and sea ice interactions explain Dansgaard-Oeschger cycles. Internationally coordinated experiments are increasingly important in providing a multimodel ensemble of climate simulations, thereby taking advantage of some cancellation of errors and allowing better quantification of uncertainty.
