Breaking the Wall to Measuring Climate Change

Falling Walls Foundation | Markus Rex, Stefanie Arndt


How the results of the longest mission to the arctic help us understand global warming

There is no challenge to humanity as big as climate change. While there is scientific consensus that global warming is the main driving force for climate change, the consequences for the different components of our Earth’s climate system are not yet fully understood. One place where climate change is most prominent is also one of the most remote and unforgiving: the Arctic Ocean. To overcome the lack of understanding, Markus Rex (Head of Atmospheric Physics) and Stefanie Arndt (Sea Ice Physicist) both at the Alfred-Wegener-Institut, the Helmholtz Centre for Polar and Marine Research in Bremerhaven respectively led and participated in the MOSAiC expedition. Between 2019 and 2020 the German icebreaker Polarstern spent a year drifting through the Arctic Ocean trapped in ice. The goal was to improve the understanding of the full seasonal cycle of processes and interactions in the coupled polar climate systems between the atmosphere, sea ice, ocean, and ecosystem to provide guidance for improving climate models. At Falling Walls, Markus and Stefanie will share their insights on the rapid change of the ice-covered Arctic Ocean and the effect this will have on all of us within the next decades.


Markus Rex

Alfred Wegener Institute

Prof. Dr. Markus Rex leads the section „Atmospheric Physics“ of the Alfred-Wegener-Institute and is full professor at the University of Potsdam. He studied Physics, Meteorology and Geophysics in Braunschweig and Göttingen, received a PhD from the FU Berlin, habilitated at the University of Bremen, has worked at NASA’s Jet Propulsion Laboratory, California Institute of Technology in the US, was Erskine fellow at the University of Canterbury in New Zealand and has teached at the FU Berlin and the University of Bremen. In 2019-2020 he led MOSAiC, the largest Arctic expedition ever.

Stefanie Arndt

Alfred Wegener Institute

Dr Stefanie Arndt is a sea-ice physicist at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research in Bremerhaven. She also lectures in the Sea Ice Physics master’s programme at Universität Hamburg. At the AWI, she coordinates the sea ice programme at the German Antarctic research station Neumayer III and the section’s field work in the ice-covered Southern Ocean. She has participated in 9 ship-based and 2 land-based expeditions to the Arctic and Antarctic, including the MOSAiC expedition, in which she led the international sea ice team on board during the third leg of the expedition.
