Debate

The European Science Foundation (ESF) and the French Foundation of the Maison des Sciences de l’Homme (FMSH) (within the Entre-Sciences programme) have agreed to jointly develop a new conference series in environmental sciences; an effort to actively foster exchanges between scientists working in the humanities and social sciences and their colleagues in the life and natural sciences. This interdisciplinary conference present the new advances in the modelling of the Global Change that combines Geosciences and Economics, with a perspective view from history - given the novelty of their interrelations – and from political science – given the impact of the ...

The State of UK Climate Modelling

The UK recently invested £23 million (~US$40 million) in a program in Quantifying and Understanding the Earth SysTem (QUEST). The final product of this investment is the state-of-the-art QUEST Earth System Model (QUESM), which is comprised of the most comprehensive modeling and understanding of terrestrial, atmosphere, and marine processes ever built. QUESM is to be linked with the world-leading Hadley Centre’s GCM to assess and understand changes in the Earth system with respect to climate and global change. Here, I present the state of UK climate modeling, an overview of the QUEST Earth System Model, and detail the individual sub-models ...

Data-Model Fusion Approach in Global Change Research: Recent Development and Future Challenges

It is increasingly recognized that global change research requires methods and strategies for combing process models and data in systematic ways. This is leading to research towards the application of model-data fusion approach. The model-data fusion is a new quantitative approach to model analysis and data assimilation that provides a high level of empirical constraint over model predictions based on observations. Applications of model-data fusion require (a) a model that describes the underlying physical, chemical and biological processes, (b) experimental observations and (c) an optimization tool. The optimization tool is used to find optimal estimates of model parameters or states ...

Linking Adaptation and Mitigation for Climate Risk Reduction

How people privately and collectively adapt to climate risk can affect the costs and benefits of public mitigation policy (e.g., Kyoto); an obvious point often neglected in actual policy making. Herein we use the economic theory of endogenous risk to address this optimal mix of mitigation and adaptation strategies, and examine how increased variability in climate change threats affects this mix. We stress that a better understanding of the cross-links between mitigation and adaptation would potentially make it possible to provide more risk reduction with less wealth. Policies that are formulated without considering the cross-links can unintentionally undermine the effectiveness ...

Atelier 5 : Migrations en héritage, mémoires de migrants

Que font les ancien(ne)s migrant(e)s de leur expérience ? Quel rôle joue leur vécu migratoire pour leurs proches ? Dans quelle mesure la migration appartient-elle à cette « deuxième génération » non migrante, mais pourtant désignée sous le signe de cette « différence » ? Ces interrogations témoignent de l’importance de la mémoire des migrants pour leur descendance. L’expérience migratoire, événement biographique marquant, constitue un héritage majeur pour les générations suivantes, même si elle n’est toujours transmise explicitement. L’héritage de la migration et ses modes d’appropriation représentent donc un angle d’analyse fondamental pour comprendre les migrations et leurs impacts à ...
