In late April, the Earth Commission, which is part of the Global Commons Alliance, a platform aiming to transform the global economy so that society can prosper on a stable and resilient planet, took an important step towards this goal by establishing its first working group, the Earth and Human System Modeling Intercomparison Project (EHSMIP).

The work will build on both Earth system models – which includes climate and other parts of the biosphere – and so called integrated assessment models, which integrate natural and socioeconomic and other human systems. 

The international group of renowned scientists led by Nebojsa Nakicenovic, an emeritus scholar at IIASA, and Govindasamy Bala from the Indian Institute of Sciences, are all active in world leading modeling initiatives such as the Intergovernmental Panel on Climate Change, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, The World in 2050, and Future Earth’s global research project Analysis, Integration and Modeling of the Earth System.

Working group co-leads: 

Govindasamy Bala, Indian Institute of Science
Nebojsa Nakicenovic, IIASA


Kristie Ebi, University of Washington
Peng Gong, Tsinghua University
Tim Lenton, University of Exeter
Ricarda Winkelman, Potsdam Institute for Climate Impact Research 
Long Cao, Zhejiang University
Peter Cox, University of Exeter
Pierre Friedlingstein, University of Exeter
Patricia Pinho, University of Sao Paulo
Keywan Riahi, IIASA
Maisa Rojas Corradi, Universidad de Chile
Detlef van Vuuren, PBL Netherlands Environmental Assessment Agency

The working group is supported by staff hosted by Future Earth, the International Institute of Applied Systems Analysis, Potsdam Institute for Climate Impact Research, and the University of Exeter.
