Infrastructure for the European Network for Earth System modelling - Phase 2 (IS-ENES2), InfraStructure for the European Network for Earth System Modelling (IS-ENES)

IS-ENES will develop a Virtual Earth System Modelling Resource Centre (V.E.R.C.), integrating the European Earth system models (ESMs) and their hardware, software, and data environments. The overarching goal of this e-infrastructure is to further integrate the European climate modelling community, to help the definition of a common future strategy, to ease the development of full ESMs, to foster the execution and exploitation of high-end simulations, and to support the dissemination of model results and the interaction with the climate change impact community. The V.E.R.C. encompasses models, the tools to prepare, evaluate, run, store and exploit model simulations, the access to model results and to the European high-performance computing ecosystem in particular the EU large infrastructures DEISA2 and PRACE. The V.E.R.C. developed by IS-ENES is based on generic ICT, Grid technology and subject-specific simulation codes and software environments. The European Network for Earth System Modelling (ENES) leads IS-ENES. This network gathers the European climate and Earth system modelling community working on understanding and prediction of future climate change. This community is strongly involved in the assessments of the Intergovernmental Panel on Climate Change and provides the predictions on which EU mitigation and adaptation policies are elaborated. IS-ENES combines expertise in Earth system modelling, in computational science, and in studies of climate change impacts. IS-ENES will provide a service on models and model results both to modelling groups and to the users of model results, especially the impact community. Joint research activities will improve the efficient use of high-performance computers, model evaluation tool sets, access to model results, and prototype climate services for the impact community. Networking activities will increase the cohesion of the European ESM community and advance a coherent European Network for Earth System modelling.

ForMaT2: CMF - Clima Media Factory Potsdam (Innovationslabore)

Das interdisziplinäre Vorhaben Climate Media Factory Potsdam (CMF) verknüpft interdisziplinär Expertisen der Hochschule für Film und Fernsehen Konrad Wolf Potsdam-Babelsberg (HFF) und des Potsdam Instituts für Klimafolgenforschung (PIK). Das Forschungs-, Entwicklungs- und Wissenspotenzial beider Einrichtungen wird einem bisher nicht wahrgenommenen Verwertungszusammenhang zugeführt. Die Verwertungsperspektiven beziehen sich auf die im Screening identifizierten Medienbedarfe, auf die Marktdefizite der Integration klimawissenschaftlicher Expertise in die Entwicklung von Medienprodukten und auf die unter anderem als Folge dieser Defizite identifizierten Produktmängel und ungenutzten Potenziale für Klimamedien. In zwei aufzubauenden Innovationslaboren soll die Entwicklungsarbeit im Hinblick auf die Verwertung erfolgen - einerseits als wissensbasierte Klimamedien auf den Medienmärkten und andererseits gegenüber den weltweit agierenden Akteuren und Institutionen der immer bedeutsamer werdenden weltweiten Klimakampagnen. Im Rahmen des Screenings wurden Innovationslabore konzipiert, die sich darauf fokussieren, Schnittstellen zu finden und klimawissenschaftliche Erkenntnisse in Medienprodukte zu transferieren. Die Innovationslabore haben prozessinnovierende wie produktinnovierende FuE-Ansätze zum Gegenstand.

Climate Change and Variability: Impact on Central and Eastern Europe (CLAVIER)

Objective: Observational records show that the global climate is changing and ongoing changes are also visible in Central Eastern Europe. About 64Prozent of all catastrophic events in Europe since 1980 can directly be attributed to weather and climate extremes. Climate change projections show even an increasing likelihood of extremes. Certainly negative impacts of climate change will involve significant economic looses in several regions of Europe, while others may bring health or welfare problems somewhere else. Within CLAVIER three representative Central and Eastern European Countries (CEEC) will be studied in detail: Hungary, Romania, and Bulgaria. Researches from 6 countries and different disciplines will identify linkages between climate change and its impact on weather patterns with consequences on air pollution, extremes events, and on water resources. Furthermore, an evaluation of the economic impact on agriculture, tourism, energy supply and the public sector will be conducted. This is of increasing importance for CEEC, which are currently facing a rapid economic development, but also for the European Union as e.g. Romania's and Bulgaria's high vulnerability from extreme events such as floods will impact not only the respective economic goals for joining the EU but also the EU solidarity fund. CLAVIER will focus on ongoing and future climate changes in Central and Eastern European Countries using measurements and existing regional scenarios to determine possible developments of the climate and to address related uncertainty. In addition, climate projections with very high detail will be carried out for CEEC to fulfil the need for a large amount of detail in time and space, which is inherent in local and regional impact assessment.

ROBIN - Die Rolle von Biodiversität und Ökosysteme für die Reduktion von Klimawandelfolgen

Um das volle Potential von tropischen Wäldern für die Reduktion von Klimawandelfolgen (CCM) und das Angebot von anderen Ökosystemleistungen unter Bedingungen des globalen Wandels zu verstehen, müssen wir unser Verständnis der Beziehungen zwischen Biodiversität (BD) und sozio-ökologischen Prozessen, durch die wir auf Veränderung reagieren und uns anpassen, verbessern. ROBIN bietet Informationen für Politik- und Ressourcennutzungsoptionen mittels Szenarien des sozio-ökonomischen und klimabezogenem Wandels durch: Quantifizierung von Interaktionen zwischen terrestrischer Biodiversität, Landnutzung und CCM Potential im tropischen Lateinamerika; Entwicklung von Szenarien für CCM Optionen durch eine Evaluation ihrer Effektivität, ihrer unbeabsichtigten Auswirkungen auf andere ökosystemare Leistungen (z.B. Verringerung von Krankheitsfällen) und ihrer sozio-ökologischen Konsequenzen. Erreichen wollen wir das durch die Kombination von neuen Techniken (inkl. Fernerkundung) für Biodiversitätsmessungen in komplexen multi-funktionalen Landschaften, durch datenbasierte Analyse, und durch integrierte Modellierung und partizipative Ansätze auf lokaler und regionaler Ebene. Anhand einer Reihe von Fallbeispielen in Mesoamerika und in Amazonien versuchen wir die Beziehungen zwischen Biodiversität und CCM Optionen und Entwicklungen in der Ernährungspolitik zu verstehen. Diese Studien verbessern unser Wissen zu CCM Optionen, die der von Stakeholdern favorisiert werden, und unser Verständnis für Faktoren, die die Einführung von Ressourcenmanagementstrategien behindern oder fördern.

Climate change - Learning from the past climate (Past4Future)

Objective: Past4Future will combine multidisciplinary paleoclimate records from ice cores, marine cores, speleothems, pollen and other records, concentrating on a global distribution of the records, to reconstruct climate change and variability during the present interglacial (the Holocene) and the last interglacial (known as the Eemian in northwestern Europe and as marine isotope stage 5e in the marine sediment records). The records will be combined in integrated analyses aided by proxy modeling and assimilation, to gain understanding of the climate processes involved in the dynamics of interglacial climates. Earth system models (ESM) including physical and biogeochemical processes will be applied to simulate the past and present interglacial climate, and to confront and intercompare the simulations with climate changes as observed from the palaeodata; this will both advance the models and our understanding of the dynamics and predictability of the climate system. Focus will be on the most recent two interglacial periods, as these provide the highest-resolved most comprehensive data records. Moreover the last interglacial represents a situation where the mean state was warmer than at present in large regions due to orbital forcing, thereby allowing tests of climate system sensitivity to constrain projections of potential future ice sheet, sea-level, circulation and biogeochemical changes. The data and Earth system model results will be used improve our capabilities to project future global and regional warming from a better understanding of relevant paleoclimates, especially in relation to sea level changes, sea ice changes and thermohaline circulation changes. The Past4Future program will draw together a world leading team of European and international partners in a concerted effort to advance our knowledge on the causes, processes and risks of abrupt changes in warm periods, such as those projected for the current and the next century. The program will inform the international debate on climate system stability and the dissemination of results will be targeted to both citizens and governmental and non-governmental stakeholders. It will leave a legacy of improved understanding of past drivers of sea level changes, changes of sea ice, and of greenhouse gas concentrations, and it will train a new generation of young climate researchers to further advance research and improved future predictions for the benefit of society and our capacity to mitigate and adapt to climate changes.

Pan-European Gas-AeroSol-Climate Interaction Study (PEGASOS)

To provide a scientifically sound basis for air quality and climate protection measures the Zeppelin is observing radicals and aerosols in the atmospheric layers close to the ground over Europe. Objective: The Pan-European Gas-AeroSOls-climate interaction Study (PEGASOS) European large scale integrating project brings together most of the leading European research groups, with state-of the-art observational and modelling facilities to: (1) Quantify the magnitude of regional to global feedbacks between atmospheric chemistry and a changing climate and to reduce the corresponding uncertainty of the major ones. (2) Identify mitigation strategies and policies to improve air quality while limiting their impact on climate change. The project is organized into four scientific Themes designed to optimize the integration of methodologies, scales, and ultimately our understanding of air quality and climate interactions: (I) Anthropogenic and biogenic emissions and their response to climate and socio-economy (II) Atmospheric interactions among chemical and physical processes (III) Regional and global links between atmospheric chemistry and climate change (IV) Air quality in a changing climate: Integration with policy PEGASOS will bridge the spatial and temporal scales that connect local surface-air pollutant exchanges, air quality and weather with global atmospheric chemistry and climate. Our major focus for air quality will be Europe including effects of changes in pollutant emissions elsewhere and the time horizon for the study will be the next 50 years. During the project we will provide improved process understanding in areas of major uncertainty for better quantification of feedbacks between air quality and a changing climate. We will present, for the first time, a fully integrated analysis of dynamically changing emissions and deposition, their link to tropo-spheric chemical reactions and interactions with climate, and emerging feedbacks between chemistry-climate and surface processes. We will target both local and regional scales, taking into account chemistry and climate feedbacks on the global scale.

EU Cloud intercomparison, process study and evaluation project (EUCLIPSE)

Objective: Cloud feedbacks remain the largest source of uncertainty in projections of future climate. They are also a major contributor to uncertainty in other feedbacks (e.g., surface albedo, carbon cycle) in the Earth System. Through interactions with the large-scale circulation, cloud processes also contribute to synoptic circulations and regional climate. They are therefore critical to the prediction of future changes in precipitation patterns, climate variability and extreme events. The central objective of EUCLIPSE is to reduce the uncertainty in the representation of cloud processes and feedbacks in the new generation of Earth System Models (ESMs), in support of the IPCC's fifth assessment report. Novel, process-oriented evaluations of clouds in present-day and future climate simulations made by the leading European ESMs will identify the cloud types and processes responsible for the spread in climate sensitivity and future precipitation changes across the models, and for deficiencies in the simulation of the present-day climate. The new diagnostics and metrics developed in EUCLIPSE will inform targeted sensitivity experiments to isolate the processes responsible for cloud feedback uncertainty. In EUCLIPSE, four distinct communities will work together across a set of integrated work packages over a four-year period: the observational community will provide state-of-the-art measurements from ground- and space-based active and passive remote sensing; the numerical weather prediction community will provide analyses of short timescale model biases induced by cloud processes; the cloud modeling community will provide fine-scale models as an additional tool for understanding cloud behavior in a changing climate; finally, the climate modeling community will synthesize the physical understanding and observational constraints identified by the other communities to improve the representation and assessment of cloud processes in ESMs and so improve the predictive skill of ESMs.

MEDiterranean Sea Acidification in a changing climate (MEDSEA)

Objective: Increases of atmospheric CO2 and associated decreases in seawater pH and carbonate ion concentration this century and beyond are likely to have wide impacts on marine ecosystems including those of the Mediterranean Sea. Consequences of this process, ocean acidification, threaten the health of the Mediterranean, adding to other anthropogenic pressures, including those from climate change. Yet in comparison to other areas of the world ocean, there has been no concerted effort to study Mediterranean acidification, which is fundamental to the social and economic conditions of more than 400 million people living along its coastlines and another 175 million who visit the region each year. The MedSeA project addresses ecologic and economic impacts from the combined influences of anthropogenic acidification and warming, while accounting for the unique characteristics of this key region. MedSeA will forecast chemical, climatic, ecological-biological, and socio-economical changes of the Mediterranean driven by increases in CO2 and other greenhouse gases, while focusing on the combined impacts of acidification and warming on marine shell and skeletal building, productivity, and food webs. We will use an interdisciplinary approach involving biologists, earth scientists, and economists, through observations, experiments, and modelling. These experts will provide science-based projections of Mediterranean acidification under the influence of climate change as well as associated economic impacts. Projections will be based on new observations of chemical conditions as well as new observational and experimental data on the responses of key organisms and ecosystems to acidification, which will be fed into existing ocean models that have been improved to account for the Mediterranean's fine-scale features. These scientific advances will allow us to provide the best advice to policymakers who must develop regional strategies for adaptation and mitigation.

The Changing Arctic and Sub-Arctic Environment: A Research and Training Programme on Marine Biotic Indicators of Recent Climate Changes in the High Latitudes of the North Atlantic (CASE)

The main aim of the CASE Initial Training Network Programme is to train the next generation of European paleo-climate scientists via state-of-the-art training in marine biotic proxies and modeling of past climate changes. It will be implemented through a joint research project aiming to describe and identify the mechanisms and impacts of recent environmental changes in the Nordic Seas. The composition of the consortium reflects the various expertises on marine biotic indicators needed to efficiently evaluate the nature and amplitudes of oceanographic and climate changes and their implications on the structure of the marine ecosystem during the present interglacial, the Holocene. The project is designed according to specific expertises of each network participant and the contribution of associated industry partners, hereby providing an ideal setting for training actions to the benefit of early stage researchers (ESR). CASE will therefore address the following key scientific objectives: 1, Advance our fundamental understanding on the impact of various natural climatic forcing factors in high northern latitudes during the Holocene. 2, Obtain a more complete knowledge on Holocene natural variability of physical parameters affecting ecosystem processes and structure in the Nordic Seas. 3, Improve our understanding and quantification of Holocene changes in ocean circulation and climate variability of the Arctic and Subarctic domains. 4, Expand our knowledge of previous Holocene polar amplifications of warming. 5, Gain fundamental knowledge of the impact of global warming beyond the range of Holocene natural variability over the last 150 years on the Nordic Seas environmental system.
