DESCRIPTION:Ian Delaney\, lecturer at the Institute of Earth Surface Dyna
 mics\, UNIL\nEsther Breuninger\, PhD student in Inorganic Environmental G
 eochemistry at the ETH Zürich and Eawag\, Swiss Federal Institute of Aqua
 tic Science and Technology\nThe CLIMACT seminar series “How to move fo
 rward and act on climate change” is an interactive online event. It tak
 es place twice a month\, every second Monday during your lunch break\, wit
 h two new speakers. Each episode aims to strengthen the dialogue and colla
 boration between key UNIL and EPFL scientists\, swiss politicians\, entrep
 reneurs and various actors from the civil society\, through collective ref
 lection. A wide range of climate change-related topics will be discussed\,
  integrating perspectives from all sectors and academic disciplines in ord
 er to generate new leads and initiatives towards systemic solutions. Parti
 cipants are welcome to take part in the discussion in English or French.\n
 \nBeginning to understand a changing landscape: insights from a long boat 
 trip in the Arctic\nBy Ian Delaney\, lecturer at the Institute of Earth 
 Surface Dynamics\, UNIL\n\nHow do landscapes in the Arctic respond to incr
 eased glacier melt and retreat? As the climate warms\, what changes should
  we expect? Can existing research on Swiss glaciers contribute to a better
  understanding of the Arctic?\n\nGlaciers impact landscapes by eroding the
 ir bedrock and creating sediment. As glacier melt increases\, erosion will
  change.  A number of parallels can be drawn between the processes in the
  Swiss Alps glaciers\, where some baseline knowledge exists\, and glaciers
  in the Arctic. Yet\, still much needs to be learned on the relationship b
 etween glacier erosion and climate in the Arctic\, a topic we currently kn
 ow very little about.\n\nGet firsthand insights with Ian Delaney\, a membe
 r of the summer 2021 Arctic Century Expedition. Bringing together peers fr
 om around the world\, this unique 5-week expedition made it possible to vi
 sit hard-to-access field sites and collect rare data. For Dr. Delaney\, th
 is expedition was an opportunity to collect records of erosion and glacier
  condition in the Russian Arctic\, which may yield insights into this regi
 on’s past landscapes.\n\nTrace element cycling in the atmosphere: implic
 ations for nutrition and health\nBy Esther Breuninger\, PhD student in I
 norganic Environmental Geochemistry at the ETH Zürich and Eawag\, Swiss F
 ederal Institute of Aquatic Science and Technology\n\nAtmospheric depositi
 on delivers essential but also toxic trace elements to ecosystems includin
 g agricultural soils. The concentration and chemical form (speciation) of 
 these elements in the environment is an important factor that controls exp
 osure to these elements\, for example via nutrition. What factors control 
 the concentration and speciation of health-relevant trace elements?\n\nEst
 her Breuninger will discuss some of the key elements that can contribute t
 o understand and predict how trace element cycles respond to environmental
  and climate change and how this will affect health and nutrition.
