DESCRIPTION:The CLIMACT seminar series “A Climate of Transformation” i
 s an interactive online event. It takes place twice a month\, every second
  Monday during your lunch break\, with two new speakers.\nEach episode aim
 s to strengthen the dialogue and collaboration between key UNIL and EPFL s
 cientists\, swiss politicians\, entrepreneurs and various actors from the 
 civil society\, through collective reflection.\nA wide range of climate ch
 ange-related topics will be discussed\, integrating perspectives from all 
 sectors and academic disciplines in order to generate new leads and initia
 tives towards systemic solutions.\nYour expertise\, ideas\, critical think
 ing and vision for the future is essential. \nJoin CLIMACT in the discuss

 onservation of high-mountain lakes\nPresented by Anna Carratala Ripolles I
   Research scientist at the School of Architecture\, Civil and Environmen
 tal Engineering (ENAC) I EPFL\n\n\nAlpine lakes are excellent sentinels of
  climate change as their chemistry and biology respond rapidly to environm
 ental forcing. The Swiss alps are host to over 1500 alpine lakes\, many of
  which have been newly mapped and thus never been studied. Microorganisms 
 play major ecological roles in these lakes\, for example in their primary 
 production\, the cycling of elements\, and the environmental attenuation o
 f contaminants. It is uncertain how physical climatic changes may affect m
 icrobial communities and consequently\, their activities in alpine lakes. 
 2000LAKES is an innovative research project joining forces between scienti
 sts and citizens to jointly describe the unexplored microbial diversity in
  Swiss alpine lakes. In the first phase of the project\, we sampled more t
 han 60 lakes in the Alps and catalogued their microbial communities using 
 metagenomics while building a culture collection of more than 200 bacteria
  species. In addition\, we established a pilot program in which citizens c
 an actively participate in our sampling campaigns and research. Our first 
 results show that Swiss alpine lakes represent hotspots of microbial diver
 sity and niches for the development of distinct bacteria communities. In t
 he future\, we aim to expand the 2000LAKES project by building an open res
 earch initiative which can contribute to expand the knowledge about the ec
 ology of alpine lakes and to take actions to anticipate and respond to the
  consequences of climate change on Swiss alpine lakes.\n\nClimate change\,
  air pollution\, brain and behaviour\nPresented by Bogdan Draganski I Prof
 essor and Director Laboratory for Research in Neuroimaging I Director MRI 
 Platform I Department of Clinical Neurosciences I CHUV - UNIL\n\n\nThere i
 s mounting evidence about the direct and indirect impact of climate change
  and air pollutants on human brain and behaviour. Stroke incidence and sev
 erity\, exacerbations of multiple sclerosis\, migraine and depression are 
 among the well-documented brain disorders impacted by temperature extremes
  and variability. We sought to investigate the impact of global warming on
  individuals’ cognition and mood\, whilst testing the interaction with d
 emographic\, socio-economic\, cardio-vascular risk\, and lifestyle factors
 . Building on data from the longitudinal Lausanne community-dwelling cohor
 t CoLaus|PsyCoLaus (www.colaus-psycolaus.ch) we demonstrate an association
  between land surface temperature changes in the last decade and the Globa
 l Assessment of Functioning score as a variable sensitive to mental health
  in 2’677 study participants. We are still left with the final step that
  will link the georeferencing patterns of environmental changes with brain
  tissue microstructure estimates and derive characteristic anatomy fingerp
 rints whilst accounting for the effects of demographic\, socio-economic an
 d cardio-vascular variables.\n\nEffect of fluid composition on the brittle
  to ductile transition of rocks: implications for deep geothermal energy\n
 Presented by Francesco Lazari I Doctoral assistant at the Laboratory of Ex
 perimental Rock Dynamics\, Civil and Environmental Engineering I EPFL\n\n\
 nDeep high-enthalpy geothermal energy is one of the renewable energy sourc
 es that can help mitigate climate change. Rocks capable of hosting fluids 
 at the necessary pressures and temperatures for deep high-enthalpy geother
 mal energy might be at or beyond the brittle to ductile transition\, where
  the mechanical and hydraulic properties of fluid-hosting rocks are largel
 y unknown.\nWe developed a new 4-electrodes setup to measure complex elect
 rical conductivity during the deformation of rocks in pressure and tempera
 ture. This\, together with in-situ measurements of rock permeability\, wil
 l allow us to investigate the role of fluid chemistry on the mechanical pr
 operties of rocks across the brittle to ductile transition\, to better und
 erstand the behavior of deep geothermal reservoirs.\n\n\n\n\n\n\n\n
