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 Sustainability of Kyoto's Architecture: Where Did the Victims of Climate Change Go?

cept of “expropriation” in the case of territories exposed to a rise in sea levels. The premise of my project is that although future generations in all countries will be affected by climate change, the inhabitants of poor countries and small island states will be especially hard hit in less than 30 years; however, their situation has been neglected by the current international regime. This neglect can be demonstrated and explained using approaches from political science (mainly policy analysis and the Advocacy Coalition Framework by Sabatier), which says that the decisions behind privileged tradable pollution rights and the valuation of ...

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 ...

L'année internationale de la planète terre

En réunissant des scientifiques, des experts du Groupe intergouvernemental d'étude du climat (GIEC), des représentants d'administrations et d'institutions de diffusion de (information scientifique, le colloque se propose de mettre en évidence comment des disciplines scientifiques aussi différentes que les sciences de la Terre et de l'atmosphère, les sciences naturalistes et les sciences économiques, convergent pour estimer les conséquences néfastes du changement climatique et fournir des éléments de réponse de nature politique pour en atténuer les effets et permettre les nécessaires adaptations. Comment en est-on arrivé, dans une perspective historique, au « Global Warming » actuel ? Comment le traitement ...

Social Impact of global Environmental Change on Farming Communities on the Ogoli River Bank in Otukpo Area of Benue State, Nigeria

One of the manifestations of the global change in this study area is a marked reduction in the duration and amount of rainfall. This adversely affects the volume of the head waters that ultimately determine the volume of the Ogoli River which is used for irrigation. Consequently, food security and livelihood of the farming communities whose mode of agricultural production is rain-fed is adversely affected. Using Participatory Learning Action (PLA) technique involving three distinct groups of adult male, adult female and youth, the study seek to evaluate the coping mechanisms of these vulnerable group to draught and reduced volume of ...

Climate, Geography and Macroeconomics: Revised Data, Refined Analysis and New Findings

Assessments of social and economic impacts of climate change are primarily based on the results of biophysical climate impact models, which are aggregated, extrapolated and/or valued in monetary terms. Another potential source of information on climate impacts are spatial and/or temporal analogues, such as Ricardian analysis of climate impacts on agriculture. Another recent effort to this end involves the development of the G-Econ database (Nordhaus, 2006), which describes the relationship between climatic and geographic factors on the one hand and regional economic productivity on the other. A multivariate regression derived from this database has been used to estimate global economic ...

Setting Cumulative Emissions Targets to Reduce the Risk of "Dangerous" Climate Change

The ultimate objective of climate change mitigation is to reduce the amount of anthropogenic greenhouse gas (GHG) emissions in order to achieve “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system” (UNFCCC, Article 2). This statement raises a number of questions regarding (i) what “dangerous interference” means, (ii) what GHG concentration level may considered “safe”, and (iii) what emissions pathway should be taken towards stabilization. Here we present a novel approach to coupled climate-carbon cycle modelling which allows one to estimate the probability that any given level of ...
