  3. Our Situation… The North Atlantic Ocean is one of the most important drivers for the variability of the global ocean circulation on time scales beyond inter-annual Global climate variability is to a large extent triggered by changes in the North Atlantic sea surface state The quality and skill of climate predictions depends crucially on a good knowledge of the northern sea surface temperatures (SST) and sea ice distributions On a regional scale, these parameters strongly impact on weather and climate in Europe, determining precipitation patterns and strengths, as well as changes in temperature and wind patterns Knowledge of these factors, and of their development in the years to come, is of paramount importance for society and key economic sectors, which have to base their planning and decisions on robust climate information

  4. NACLIM = North Atlantic Climate Predictability of the Climate in the North Atlantic/European sectorrelated to North Atlantic/Arctic Ocean temperature and sea ice variability and change Workshop: Towards Urban Climate Services Brussels, 21. – 22. June 2016 11.2012 – 01.2017

  5. Facts and Figures • Financed by the European Commission • Large Scaled Collaborative Project under FP7 • Duration: 51 Months, 1 Nov. 2012 – 31 Jan. 2017 • Research Focus: Assessment of decadal climate forecasts • Partners: 19 institutions from 9 European countries • 5 Core themes, 12 work packages • Project costs: approx. 12 M€ • EU contribution: approx. 9 M€

  6. What NACLIM does Investigating and quantifying the predictability on interannual to decadal time scales of the climate in the North Atlantic/European sector related to North Atlantic/Arctic Ocean surface state (SST and sea ice) variability and change NACLIM partly builds on the multi-model decadal prediction experiments currently performed by a number of leading European and worldwide research institutions as part of the Coupled Model Intercomparison Project Phase 5 (CMIP5) Rather than running climate forecasts within the project, we analyze the CMIP5 predictions and critically assess their quality for the near-future stage of atmospheric and oceanic quantities

  7. Expected Outcome Quantifying the uncertainty of state-of-the-art climate forecasts by evaluating the ability to model the most important oceanic and atmospheric processes in the North Atlantic and Arctic Oceans, and by comparing key quantities with observations Optimizing the present North Atlantic observation system by evaluating the impact of its components on the quality and quality control of model forecasts, and their value in determining the present ocean state and its past variability Quantifying the impact on oceanic ecosystems and on European urban societiesof predicted North Atlantic/Arctic Ocean variability (case studies) Critically assessing the use of climate forecast parameters for use by stakeholders in society, politics and industry (case studies)

  8. Core Themes and Interaction ECOMS

  9. 4.1: Focus on Ecosystems – Link to Marine Biology Changes in the ocean circulation can have dramatic consequences for fish populations and consequently for the fishing industry Key example: the blue whiting NACLIM researchers analyse among others the predictability of the physical changes and its effect on fisheries, providing information which is very useful economically

  10. 4.2: Focus on Urban Societies Global climate change can be amplified on the local scales of cities, where to date about half of the word‘s population is living. Key example: Urban heat Islands Climate predictions with good spatial resolution, pecific to cities, can be used to make decisions, i.e. in the area of healthcare, energy and infrastructural sectors WP4.2 is operated by VITO and GIM in Belgium Cities selected for case studies: Berlin, Antwerp, Almada

  11. Why are we here today? “Scientists need to understand the questions of the stakeholders and need to build a dialogue. Although the next climate change-related disaster may not arrive the day after tomorrow, it is safe to predict that it will arrive one day, and we’d better be prepared “ - Hans von Storch

  12. Why are we here today? The project downscales the CMIP5 European climate change predictions to the urban scale, using a deterministic urban climate model in order to match the scale of interest for local stakeholders The resulting high resolution urban climate predictions have been coupled to relevant socio-economic data for the selected European cities in order to produce heat risk maps The information on urban climate risk results needs to be communicated with Local Stakeholders such as city authorities, the private sector or the industry and have their Feedback, Suggestions and Requests Further exchange among projects such as NACLIM, EUPORIAS, UrbanSIS… with climate service community as well as international and national prediction agenciesis essential

  13. Workshop outline • NACLIM andthecities • End usersfromEnergyandTourismsectors, UHI-Strategyplans • 7:30 p.m. DINNER at Madame Chapeau • European FundingAgencies • Climate Service • Research Projects • DiscussionsandWrapUp

  14. Topical questions Topics for group discussion on 22nd June afternoon *1.1 Needs of the end-users in terms of climate service (UHI, flooding, sea level rise etc.) and the technical implementation (web-based platforms, maps...)*1.2 How to actively market the service provided by and for the climate services (sustained development for project output)

  15. Open Access & Open Data Interested in our research? NACLIM supports Open Access to peer-reviewed publications Open Data are applied for the impact studies of the selected cities You can find our publications and data on * OpenAIRE Orphan Repository(only publications)www.openaire.eu * ZENODO Repository (NACLIM community available, publications and data)https://zenodo.org/collection/user-naclim where researchers, scientists, EU projects and institutions share, preserve and showcase their multidisciplinary research results. Or contact: chenbo.guo@uni-hamburg.de or NACLIM@zmaw.de

  16. The research leading to these results has received funding from the European Union 7th Framework Programme (FP7 2007-2013), under grant agreement n.308299 NACLIM www.naclim.eu Thank you

  18. Zooplankton Focus on ecosystems – Link to marine biology “We can see the signature of the sub-polar Gyre all the way throughout the North Atlantic ecosystem, from phytoplankton and zoo-plankton to pilot whales and puffins” (Mark Payne) Phytoplankton Pilot whales Puffins

  20. Communication cluster For this purpose, the NACLIM project has been clustered with two other complementary projects, EUPORIAS and SPECS by the European Commission (!!!) Joint dissemination activities will be set up in order to maximise the outreach and optimise communication reaching the final beneficiaries of the 3 projects
