IMPRESSIONS (Impacts and Risks from High-End Sce- narios: Strategies for Innovative Solutions) is developing and applying a novel participatory methodology that explicitly deals with uncertainties and strong non-linear changes using a range of scenarios focusing on high- er-end climate change, but also including intermediate and 2°C warming levels. This new methodology will create a coherent set of higher-end climate and socio-economic scenarios which will be applied to a range of climate change impact, adaptation and vulnerability models that build on theories of complex systems and address tipping elements as key characteristics of such systems. IMPRESSIONS is led by Paula Harrison at Oxford Univer- sity's Environmental Change Institute and Mark Rounsev- ell at the University of Edinburgh in the UK.


Coastal areas concentrate vulnerability to climate change due to high levels of population, economic activity and ecological values. RISES-AM addresses the economy-wide impacts of coastal systems to various types of high-end climatic scenarios (including marine and river- ine variables). It encompasses analyses from global to local scales across the full range of representative con- centration pathways (RCPs) and shared socio-economic pathways (SSPs). It considers the still significant uncer- tainties in "drivers" (physical and socio-economic) and coastal system responses (e.g. land loss or uses, biologi- cal functions, economic productivity) within a hazard-vul- nerability-risk approach. The emphasis is on the advantag- es of flexible management with novel types of coastal interventions (e.g. "green" options) within an adaptive pathway whose tipping points will be identified/quantified in the project. RISES-AM is led by Vicente Gracia at Centre Internacional d'Investigació dels Recursos Costan- ers, Spain.
