IPCC Special Report

Open Panel discussion for conference participants, the public and press
(Wednesday 25/09/2019 14:45 - 15:30)

Main results of the IPCC Special Report on Ocean and Cryosphere in a changing climate

At 11:00 am on 25 September 2019, the IPCC’s Special Report ‘Ocean and Cryosphere in a Changing Climate’ will be officially released. The report investigates physical processes in, and the effects of, climate change on marine, coastal, polar and alpine ecosystems. In addition, it addresses the consequences for human beings and outlines our options for adapting to climate-related changes so as to achieve a more sustainable future.
By hosting a public event after the IPCC press conference, the Helmholtz Climate Initiative REKLIM hopes to open its own international conference to a broader audience. In this regard, the Co-Chair of the IPCC’s Working Group II, Prof Hans-Otto Pörtner, will present the latest findings from the new Special Report in a videoconference live from Monaco, and be available to answer questions. In addition, the conference’s keynote speaker on ‘sea-level changes’, Prof Anders Levermann (PIK); Prof Beate Ratter (Universität Hamburg / HZG and lead author of Chapter 6 in the Special Report); and Dr Ingo Sasgen (AWI, REKLIM speaker on ‘sea-level changes’) will assess the report and be available for questions and discussions.

General discussion, press conference

Registration for members of the public and press:
Since this open plenary session will take place during the international REKLIM conference, it will be held in English; however, questions may also be posed in German. It will be followed by the conference’s official closing session, which you are also warmly invited to attend.
A room for conversations with the press can be provided at the end of the conference (ca. 4:30 pm).
We would be delighted if you could keep the afternoon of 25 September 2019 free (from 2:45 pm) in order to discuss this highly topical development with us as part of the environmental forum.

If you plan to join us, please send a brief email to renate.treffeisen@awi.de. Attendance is free of charge; however, given the limited occupancy available, registration is required. Feel free to forward / share this invitation with friends and colleagues who may also be interested.

Prof Hans-Otto Pörtner
(IPCC Co-Chair, Working Group II; Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research)

Hans-Otto Pörtner studied at Münster and Düsseldorf Universities where he received his PhD and habilitated in Animal Physiology. As a Research and then Heisenberg Fellow of the German Research Council he worked at Dalhousie and Acadia Universities, Nova Scotia, Canada and at the Lovelace Medical Foundation, Albuquerque, New Mexico, USA. Currently he is Professor and Head of the Department of Integrative Ecophysiology at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research in Bremerhaven, Germany. He acts as an associate editor ‘Physiology’ for Marine Biology and as a co-editor of the Journal of Thermal Biology. He was Honorary International Associate Member of the Society for Integrative Biology, USA, between 2006 and 2013. He gave the Peter Hochachka Memorial Lecture at University of British Columbia in 2007, the Plymouth Marine Lecture in 2013, and the Bidder Lecture of the Society for Experimental Biology in Florence in 2018.
During the IPCC Fourth Assessment cycle Dr Pörtner served as Lead Author on the Working Group III Special Report on Carbon Capture and Storage, and during the Fifth Assessment Cycle as Coordinating Lead Author of Chapter 6 (Ocean Systems) of the Working Group II Report, as a member of the author teams for the Working Group II Summary for Policymakers and Technical Summary, and as a member of the Core Writing Team for the Synthesis Report. In October 2015 he was elected Co-Chair of Working Group II for the Sixth Assessment cycle. His research interests include the effects of climate warming, ocean acidification, and hypoxia on marine animals and ecosystems with a focus on the links between ecological, physiological, biochemical and molecular mechanisms limiting tolerance and shaping biogeography and ecosystem functioning.

Dr Ingo Sasgen
(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Topic Speaker REKLIM Topic 2 ‘Sea level change from global to regional and local scales’

Ingo Sasgen is a senior research scientist at Alfred-Wegener-Institute Bremerhaven, in the division of glaciology. His research focus lies on mon-itoring the evolution of the ice sheets with satellite observations, as well as modelling glacial-isostatic adjustment and related sea-level change. Collab-orative research projects engaged him at Jet Propulsion Laboratories, Pasadena, USA and Pennsylvania State University, Pennsylvania, USA. Ingo Sasgen is speaker of REKLIM Topic 2 Sea level changes from global, regional to local scale.

Prof Anders Levermann
(Potsdam Institute for Climate Impact Research (PIK), Germany), Lead author IPCC AR5 Chapter 13 ‘Sea Level Change’)

Anders Levermann is a professor of Dynamics of the Climate System at the Institute of Physics of Pots-dam University & Potsdam Institute for Climate Impact Research, Head of the research domain Com-plexity Science at the Potsdam Institute and Adjunct Senior Research Scientist at the Columbia Univer-sity in New York. He was a lead author of the sea-level chapter in the Intergovernmental Panel on Climate Change (IPCC-AR5, IPCC-AR6).
His research focuses on the tipping of systems, i.e. abrupt large-scale changes with potentially strong impacts on nature and society. Developing a dynamic model of eco-nomic damage propagation for the global production- and supply net-work, he is scientific coordinator of zeean (www.zeean.net), a data portal to collect, harmonize and provide information on the vulnerability and adaption of the global economic supply network. He has published more than 110 scientific articles, and also advises government repre-sentatives, members of parliament, political parties as well as economic stakeholders and journalists pertaining to climate change. Anders Levermann is frequently giving presentations in the German Parliament and to other political and economic stakeholders (ca 20 talks per year). He is engaging in the public discourse on climate change through inter-views (ca 50 per year) and articles in national and international news-papers (e.g. Washington Post, Huffington Post, Frankfurter Allgemeine Zeitung, etc.).

Prof Beate Ratter
(University Hamburg and Helmholtz Centre Geesthacht, Germany), Lead author SROCC Chapter 6 ‘Extremes, Abrupt Changes and Managing Risks’)

Beate Ratter is a geographer who has been engaged in island studies for 30 years. Her research mainly focuses on human-nature interaction in resource and environmental management, with special empha-sis on cultural framings, perception, and political embeddedness of different regional cultures, especially on coasts and islands. She is Vice-President of the International Small Island Studies Association (ISISA) and has served as an expert for slow onset events in develop-ing countries (especially small islands) for the United Nation Framework Convention for Climate Change (UNFCCC) and United Nations Envi-ronment Programme (UNEP) (2014). Her extended conceptual and empirical work on small islands is reflected in her recent book ‘Geography of Small Islands – Outposts of Globalisation’ published by Springer in 2018. Since September 2017 she is lead author for the IPCC Special Report on Oceans and Cryosphere (SROCC). Beate Ratter has in-depth experience of qualitative and quantitative empirical research and of moderation and mediation techniques. In the interdisciplinary project DICES (Dealing with change in SIDS, DFG - Project Ra 585/19-1) within the priority programme ‘Sea level change and society’ (SPP 1889), she addresses the cultural embeddedness of climate change perception and its linkages to societal feasible adaptation strategies on the Maldives.
