| Zusammenfassung |
| The integrated Earth system model (iESM) has been developed as a new
tool for projecting the joint human/climate system. The iESM is based
upon coupling an integrated assessment model (IAM) and an Earth system model (ESM) into a common modeling infrastructure. IAMs are the
primary tool for describing the human–Earth system, including the
sources of global greenhouse gases (GHGs) and short-lived species (SLS),
land use and land cover change (LULCC), and other resource-related drivers of
anthropogenic climate change. ESMs are the primary scientific tools
for examining the physical, chemical, and biogeochemical impacts of
human-induced changes to the climate system. The iESM project
integrates the economic and human-dimension modeling of an IAM and
a fully coupled ESM within a single simulation system while
maintaining the separability of each model if needed. Both IAM and ESM
codes are developed and used by large communities and have been
extensively applied in recent national and international climate
assessments. By introducing heretofore-omitted feedbacks between
natural and societal drivers, we can improve scientific understanding
of the human–Earth system dynamics. Potential applications include
studies of the interactions and feedbacks leading to the timing,
scale, and geographic distribution of emissions trajectories and other
human influences, corresponding climate effects, and the subsequent
impacts of a changing climate on human and natural systems. This
paper describes the formulation, requirements, implementation,
testing, and resulting functionality of the first version of the iESM
released to the global climate community. |
