Speakers

Dirk Notz
University of Hamburg

Dirk Notz is professor for sea-ice research at the University of Hamburg and one of the lead authors of the most recent IPCC report. His research aims among others at a conceptual understanding of the large-scale climate evolution of our planet, with a specific focus on the past and future evolution of the sea-ice cover in the polar regions.

Dirk studied meteorology and physics in Hamburg and Seattle, and obtained a PhD in applied mathematics from the University of Cambridge, UK. He has spent a good part of his life in the polar regions for sea-ice related field work.. Among others, he has led a number of student field expeditions in the high Arctic. For the recent IPCC report, he has been lead author for the chapter on “Oceans, Cryosphere and Sea Level”, and was engaged in the final discussions on the summary for policymakers.

Besides his research, Dirk is very engaged in public outreach activities and has won several prizes for his clear communication of scientific topics. He regularly gives public presentations on climate change, with audiences including policy makers and private businesses but also elementary schools and universities.

Marilyn Raphael
University of California

Marilyn: Dr. Marilyn Raphael is the director of the University of California (UCLA) Institute of the Environment and Sustainability, Professor of Geography at UCLA, and served as Department Chair from 2010-2013. Her primary research focus is Southern Hemisphere (SH) atmospheric dynamics and climate change and her major scientific goals are to characterize the Antarctic sea ice variability and to define and understand the interaction between Antarctic sea ice and the large-scale Southern Hemisphere circulation, focusing on interaction at the seasonal, interannual and decadal time scales. Her work includes global climate modeling with an emphasis on improving the simulation of sea ice and the atmosphere in the Southern Hemisphere.

She is a member of the American Academy of Arts and Sciences, current Chair of the Scientific Committee on Antarctic Research’s expert group, Antarctic Sea ice Processes and Climate (ASPeCt) and Co-Chair of the World Climate Research Programme’s (WCRP) Polar Climate Predictability Initiative (PCPI). She has served on the National Research Council’s Committees on Future Science Opportunities in Antarctica and the Southern Ocean and Stabilization Targets for Atmospheric Greenhouse Gas Concentrations.

All you need to know

This event is part of a series of online discussions aims to advance the knowledge about tipping elements, irreversibility, and abrupt changes in the Earth system. It supports efforts to increase consistency in treatment of tipping elements in the scientific community, develop a research agenda, and design joint experiments and ideas for a Tipping Element Model Intercomparison Project (TipMip).

This discussion series is a joint activity of the Analysis, Integration, and Modeling of the Earth System (AIMES) global research project of Future Earth, the Earth Commission Working Group 1 Earth and Human Systems Intercomparison Modelling Project (EHSMIP) under the Global Commons Alliance and the Safe Landing Climates Lighthouse Activity of World Climate Research Program (WCRP).

Organized by

Analysis, Integration, and Modeling of the Earth System (AIMES)

The Analysis, Integration, and Modeling of the Earth System (AIMES) project is an international network of Earth system scientists and scholars that seek to develop innovative, interdisciplinary ways to understand the complexity of the natural world and its interactions with human activities. AIMES is a global research project of Future Earth.

Earth Commission

The Earth Commission is a major scientific assessment, hosted by Future Earth, to define a safe and just corridor for people and planet. The Commission will inform the creation of science-based targets, the “1.5-degree equivalents”, to help maintain and protect critical global commons – our shared climate, land, biodiversity, freshwater, atmosphere and oceans. The Earth Commission is an international team of leading natural and social scientists and five working groups of additional experts. It forms the scientific cornerstone of the Global Commons Alliance.

Future Earth

Future Earth is a global network of scientists, researchers, and innovators collaborating for a more sustainable planet. Future Earth initiates and supports international collaboration between researchers and stakeholders to identify and generate the integrated knowledge needed for successful transformations towards societies that provide good and fair lives for all within a stable and resilient Earth system. Future Earth is the host of the Earth Commission.

International Institute for Applied Systems Analysis (IIASA)

International Institute for Applied Systems Analysis (IIASA)is an international research institute that advances systems analysis and applies its research methods to identify policy solutions to reduce human footprints, enhance the resilience of natural and socioeconomic systems, and help achieve the sustainable development goals.

Potsdam Institute for Climate Impact Research (PIK)

The Potsdam Institute for Climate Impact Research (PIK) is advancing the frontier of integrated research for global sustainability, and for a safe and just climate future. A member of the Leibniz Association, the institute is based in Potsdam, Brandenburg and connected with the global scientific community. Drawing on excellent research, PIK provides relevant scientific advice for policy decision-making. The institute’s international staff of about 400 is led by a committed interdisciplinary team of Directors.

University of Exeter, Global Systems Institute

The Global Systems Institute (GSI) is thought-leading in understanding global changes, solving global challenges and helping create a flourishing future world together, through transformative research, education and impact. GSI's aim is to work with others to secure a flourishing future for humanity as an integral part of a life-sustaining Earth system. GSI's aim to be a ‘go to’ place for global change researchers from around the world, bringing them together with industry, policymakers, students and other stakeholders to tackle shared problems, and acting as a catalyst that enables translation of this research into applications that deliver tangible and sustainable social and ecological benefit.

WCRP Safe Landing Climates Lighthouse Activity.

The Safe Landing Climates Lighthouse Activity is an exploration of the routes to “safe landing” spaces for human and natural systems. It will explore future pathways that avoid dangerous climate change while at the same time contributing to the United Nations Sustainable Development Goals (SDGs), including those of climate action, zero hunger, clean water and sanitation, good health and well-being, affordable and clean energy, and healthy ecosystems above and below water. The relevant time scale is multi-decadal to millennial.

World Climate Research Programme

The World Climate Research Programme (WCRP) leads the way in addressing frontier scientific questions related to the coupled climate system — questions that are too large and too complex to be tackled by a single nation, agency or scientific discipline. Through international science coordination and partnerships, WCRP contributes to advancing our understanding of the multi-scale dynamic interactions between natural and social systems that affect climate.
