Impact2C Quantifying project impacts under 2 decrees Celsius warming


Description:

Political discussions on the European goal to limit global warming to 2°C demands that discussions are informed by the best available science on projected impacts and possible benefits.  IMPACT2C enhanced knowledge, quantifies climate change impacts, and adopted a clear and logical structure, with climate and impacts modelling, vulnerabilities, risks and economic costs, as well as potential responses, within a pan-European sector based analysis. IMPACT2C utilised a range of models within a multi-disciplinary international expert team and assessed effects on water, energy, infrastructure, coasts, tourism, forestry, agriculture, ecosystems services, and health and air quality-climate interactions. IMPACT2C introduces key innovations.  First, harmonised socio-economic assumptions/scenarios were used to ensure that both individual and cross-sector assessments are aligned to the 2°C (1.5°C) scenario for both impacts and adaptation, e.g. in relation to land-use pressures between agriculture and forestry. Second, it had a core theme of uncertainty, and has developed a methodological framework integrating the uncertainties within and across the different sectors, in a consistent way. In so doing, analysis of adaptation responses under uncertainty were enhanced. Finally, a cross-sectoral perspective was adopted to complement the sector analysis. A number of case studies were developed for particularly vulnerable areas, subject to multiple impacts (e.g. the Mediterranean), with the focus being on cross-sectoral interactions (e.g. land use competition) and cross-cutting themes (e.g. cities).  The project also assessed climate change impacts in some of the world’s most vulnerable regions: Bangladesh, Africa (Nile and Niger basins), and the Maldives. IMPACT2C integrated and synthesised project findings suitable for awareness raising and are readily communicable to a wide audience, and relevant for policy negotiations.

The results of the analyses undertaken in the IMPACT2C project are detailed in a user-friendly interactive IMPACT2C web-atlas
