Taking Vaud's temperature: examining Switzerland's environmental health now and in the years to come

IG: @qwertzcafe
15 May from 7 p.m.
Qwertz, Rue de la Grotte 3
1003, Lausanne
Human presence and activities have long affected Switzerland's natural environment. Join us as local scientists explore how our canton's environment is changing and how we can work with nature to mitigate these effects.

Cyanobacteria in a changing world

Diego Gonzalez (Scientist at University of Neuchâtel)
Cyanobacteria have a bad reputation: they proliferate in eutrophic lakes, where they deplete oxygen and threaten biodiversity, and sometimes accumulate on the shores of rivers, releasing a pungent smell and poisoning dogs. Often undervalued are the key role played by their ancestors in the evolution of life on earth, their sophisticated morphology and behaviour, and the richness of their interactions with plants, animals, and other microbes. In this talk, I will cover a few key aspects of the biology of cyanobacteria, including their potential responses and adaptations in a changing climate.

Trees in cities, what do they do for us?

Christoph Bachofen (Scientist at WSL Lausanne)
Worldwide cities are getting bigger and denser, and are heating up due to the urban heat island effect. In addition, heatwaves are recurring more often now, so that people in the city are regularly exposed to critical temperatures. Urban vegetation, particularly urban trees, have been proposed as a means to mitigate urban heat stress. But how much are trees able to cool down cities? Would it not be better to paint all roofs and walls white? Can urban trees also take up the CO2 we emit and help us to combat climate change?

Unraveling historical mysteries through glacier modeling

Guillaume Jouvet (Professor at Université de Lausanne, Faculté des Géosciences et de l'Environement, Centre interdisciplinaire de recherche sur la montagne )
March 1926, four men are reported missing after a hike on the great Aletsch Glacier. Their remains are found in 2012. What happened in 1926 that sealed the fate of these four men? To answer this question, we will reconstruct the history of glacier dynamics over almost a century through numerical modeling. By extending the method further back in time, we will even be able to reconstruct the evolution of the Rhône Glacier that covered Swiss Romandie during the last glacial maximum about 24,000 years ago.
