Summary The stability of the Greenland Ice Sheet (GrIS) is a threat to coastal communities worldwide. The PIs have changed our understanding of why it darkens during the melt season, becoming increasingly deep purple due to pigmented ice algal blooms in the ice surface, producing more melt and accelerating the GrIS towards its tipping point, and increasing sea level. The next step jump in our understanding of biological darkening will be provided by DEEP PURPLE, which will establish the factors that control ice algal blooms. These factors are essential for modelling of future melting, which require a process-based understanding of blooming. DEEP PURPLE will quantify the synergies between the biology, chemistry and physics of ice algae micro-niches in rotting, melting ice, and examine the combination of factors which stabilise them. State-of-the-science analytical and observational methods will be employed to characterise the complex mosaic of wet ice habitats, dependent on factors such as the hydrology, nutrient status, particulate content and light fields within these continually evolving ice-water-particulate-microbe systems. We will quantitatively assess why and how the fine light mineral dust particulates contained within the melting ice amplify the growth of ice algae. The particulate content and composition of different layers in the GrIS is dependent on age, and so the algae that the melting ice can support may fundamentally change over time. We look back to understand if the ice biome has changed through the Anthropocene via analyse of fjord sediments. The first draft genome of ice algae will show their key adaptations to glacier surface habitats. DEEP PURPLE looks forward by providing the critical field data sets and conceptual models of ice algal growth that will facilitate the next generation of predictive models of sea level rise due to biologically enhanced melting of the GrIS.

Project GENIE: GeoEngineering and NegatIve Emissions pathways in Europe

Call Details Synergy Grants (SyG), SyG, ERC-2020-SyG
Summary Geoengineering technologies, such as solar radiation management (SRM), and negative emissions technologies, such as greenhouse gas removal (GGR), are emerging options to address climate change. This project will investigate the environmental, technical, social, legal, and policy dimensions of GGR and SRM. We provide an urgently needed interdisciplinary and holistic perspective of these technologies in order to understand conditions under which they might be deployed at scale. Our meta-analytical framework integrates insights from social science, engineering and physical science disciplines to provide a comprehensive view of GGR and SRM in the transition to climate neutrality in Europe and the world. The project will conduct excellent research and generate a robust, scientific assessment for evidence-based policymaking. Our research framework consists of three pillars—techno-economic systems, socio-technical systems, and systems of political action—within which we place six work packages (WPs). These are: (1) Understanding the current state and future potential of GGR and SRM technologies in terms of their technical and economic features; (2) Analysing bottlenecks in transitions to climate neutrality and their implications for deployment; (3) Identifying social acceptance and legitimacy constraints, (4) Learning, diffusion, and adoption; (5) Implications for Sustainable Development Goals of archetypical mitigation pathways; and 6) Policy options and governance. A crosscutting WP7 synthesizes research along three salient, but under-researched themes: A) Socio-technical change; B) Managing transition risks; and C) Political economy and feasibility of deployment. WP8 focuses on stakeholder engagement, entailing scenario co-design, science-policy dialogue formats, and specific outreach formats for target groups.
