IMPACT2C at the Paris conference "Our Common Future under Climate Change"

Parallel Session: "Multi-sectoral analysis of risks to climate change (hot spots) at 2 °C warming"

Presentation by Daniela Jacob: "Cross-sectoral analysis in IMPACT2C and IPCC AR5 Europe Chapter"

Abstract content

Political discussions on the European goal to limit global warming to 2°C relative to pre-industrial levels, needs to be informed by the best available science on projected impacts and possible benefits.

Here we’ll provide a recent update of the scientific evidence on which regional changes and associated impacts will be induced by 2 °C global warming.

First, original insights and findings from the FP7 project IMPACT2C will be presented and discussed. IMPACT2C identifies and quantifies the impacts and most appropriate response strategies of a 2oC global warming. IMPACT2C analyses a number of major cross-sectoral issues for Europe and three selected vulnerable regions: Bangladesh, Africa (Nile and Niger basins) and the Maldives

The IMPACT2C project adopts a clear and logical structure within climate- and impact-modelling, vulnerabilities, risks and economic costs. Detailed climate change scenarios are provided and tailored to the needs of various sectors. Here the information from the new EURO-CORDEX simulations will be presented. Furthermore, selected innovative methods (e.g. ensemble model selection which represent the entire ensemble's spread) and tools (e.g. web atlas) will be shown.

On the pan-European level this research is also linked to the Europe-Chapter from AR5, IPCC, which assesses evidence of climate change in a regional chapter and therefore could describe impacts across sectors and identify interactions between impacts. Regional information on climate, vulnerability and adaptation strategies are also major topics. The cross-sectoral decision making which is required to address climate change is reviewed in the Chapter. The main findings of the Europe chapter of WG II IPCC AR5 will be presented.
