Professor Stefan Rahmstorf

Stefan Rahmstorf is Co-Head of Research Department on Earth System Analysis of the Potsdam Institute for Climate Impact Research (PIK) and Professor of Physics of the Oceans at the University of Potsdam.

A physicist and physical oceanographer by training, Stefan Rahmstorf's research focusses on paleoclimate, ocean circulation, sea level, extreme weather events and Earth System modeling.

After working at the New Zealand Oceanographic Institute and the Institute of Marine Science in Kiel, Stefan Rahmstorf joined PIK in 1996. He holds a professorship of Physics of the Oceans at the University of Potsdam since 2000. From 2004 to 2013 Stefan Rahmstorf advised the German government as a member of its Advisory Council on Global Change (WBGU).

He is not only an outstanding and highly cited scientist but also a sought-after science communicator and speaker, winning e.g. the Climate Communication Prize of the American Geophysical Union in 2017. He co-founded the award-winning Realclimate and KlimaLounge blogs and is Europe’s climate scientist with the most Twitter followers (2020).

Stefan Rahmstorf is professor of Physics of the Oceans at Potsdam University and head of the Earth System Analysis department of the Potsdam Institute for Climate Impact Research in Germany. He is a member of the Academia Europaea and served the German government from 2004-2013 in the German Advisory Council on Global Change (WBGU). He was also one of the lead authors of the 4th Assessment Report of the IPCC. In 2007 he became an Honorary Fellow of the University of Wales and in 2010 a Fellow of the American Geophysical Union. In 2017 Stefan Rahmstorf was the first scientist outside the US to be awarded the Climate Communication Prize of the American Geophysical Union. He has published over 130 scientific papers (40 of which in the leading Nature and Science journals and PNAS) and co-authored four books. Available in English are Our Threatened Oceans and The Climate Crisis.

Further Infos (Personal website of Stefan Rahmstorf)

Stefan Rahmstorf is an expert in ocean circulation, sea level, paleoclimate, extreme weather events and Earth system modelling. He is addressing the following main research questions:

What can we learn from natural climate changes in Earth's history?
How do climate change and ocean circulation interact in past and future?
How has sea level changed in the past, and how fast will it rise with further warming?
How are weather extremes changing, in particular linked to changes in ocean currents and the jet stream?
