Modeling adaptation to climate changes: New challenges for integrated assessment models

点击翻译按钮获取中文摘要

Climate change is one of the greatest challenges facing our planet in the foreseeable future. But despite the urgency of the situation, global GHG emissions are still increasing. In this context and since future climate changes appear now unavoidable to some extent, adaptation measures have recently re-emerged as an important component of climate polices. The general objective of the proposed research is to assess the respective role of mitigation of and adaptation to climate changes. The former strategy provides options to reduce emission levels, the latter strategies to deal effectively with climate change effects by reducing their impacts. The methodology to be used shall rely on integrated assessment modelling. This modelling approach combines key elements of the economic system and of the biophysical system, elements that are underlying the anthropogenic climate change phenomenon. A specific attention shall be given to uncertainties surrounding climate changes. Adaptation to climate changes should be considered when designing sound climate policies. The proposed research aims to contribute in that domain through the development and use of decision tools (models) for sustainable policy choices.
