Global scale impacts of climate change: a multi-sectoral analysis

Lead Research Organisation: University of Southampton
Department Name: School of Geography


Climate policy should be informed by robust and credible information on the impacts of climate change across the global domain; a global perspective also places local and regional impacts in context, and helps identify potential 'hotspots' for further scientific investigation.The project assesses the global-scale impact of climate change using a range of linked impact modules and impact indicators, representing impacts on water resources, flood risk, food production, biodiversity and human health and well-being on land, at the coast, and at sea. The project will synthesise and aggregate across sectors and regions, using a variety of approaches, and allow the identification of the risks of specific impacts occurring at different rates of climate change.The methodology and results of the project also provide a framework for the assessment of the impacts of defined climate policies. First, it allows detailed geographically-explicit assessments of specific climate scenarios or climate policies, using the suite of linked models. Second, it allows the more rapid assessment of a very large number of climate outcomes (based for example on a probabilistic assessment of the climate effects of an emissions policy) using regionalised functions relating climate impact to indices of climate forcing.The project will be undertaken by a consortium of twelve lead partners, all with international reputations in the field of climate impact assessment.
Description Influence on UK climate policy negotiators
Geographic Reach Multiple continents/international 
Policy Influence Type Citation in other policy documents
Impact The paper (Arnell et al., 2013) has been used by DECC to support its position on climate change temperature targets. The paper describes the impacts avoided by different climate change pathways, and was produced during the DECC-funded AVOID project which built upon QUEST-GSI. Subsequent research based on QUEST-GSI has been used by DECC to inform its position during the 2015 COP21 Paris climate negotiations.
