On July 6 Till Wagner of Atmospheric and Oceanic Sciences will temper the summer heat with his talk on “How Sea Ice Impacts the World.”
Description: Sea ice is a hugely consequential component of the climate system. It impacts the physical configuration of the oceans and atmosphere, it plays a key role in the yearly cycle of the polar ecosystems, it is an integral part of the traditional ways of life in the high Arctic, and it is increasingly perceived as a factor determining Arctic tourism, economic development, and geopolitics. In this talk I will discuss how sea ice works, and why we'd do well to learn more about it.
Bio: Till Wagner grew up in southern Germany and moved to the United Kingdom to study physics and philosophy in college. An early focus on modern physics in graduate school soon gave way to a fascination with applied math and its use in the geosciences. Till's postdoc years brought him to California where he learned about modeling of the climate system, in particular the polar regions. He spent the next three years in North Carolina, teaching physics and physical oceanography and continuing his research on polar climates and ice-ocean interactions. Till joined the UW–Madison Department of Atmospheric and Oceanic Sciences in July 2021. He once made a stop-motion animation of a giant glacier calving event.
