Workshop 3

Coupled climate-ecology-economy modeling and model hierarchies

Venue: Institut Henry Poincare, Paris (France), 2 - 6 December 2019

Amphithéâtre Hermite

Scientific Committee

Victor Brovkin 

Martin Claussen  

Tim Lenton 

Maria Nikolaidi


The aim of the workshop is to bring together economists, climate scientists and mathematicians who work on the interactions between climate systems, ecosystems, financial systems and the economy. Emphasis will be placed on enhancing interactions between disciplines on methodological issues and research outcomes. The workshop will also illuminate the policy implications of the recent research on climate-ecology-economy modeling. 


Professor Lars Peter Hansen, 2013 Nobel Laureate in Economics, will give a keynote speech on Wednesday
