December 2022

The OCCR is getting three new research groups:

  • The Climate and Society group is led by Heli Huhtamaa. The group investigates the complexity of eruption-climae-society causalities in the historical past, from the late medieval times to the modern era. 
  • The Sedimentary Geochemistry group is led by Hendrik Vogel. The group uses Cenozoic sedimentary records to provide concrete narratives about past climates and environments, using a variety of analytical approaches.
  • The Geocomputation and Earth Observation group is led by Benjamin Stocker. The group develops new ways to detect, quantify, and predict responses of vegetation and land surface processes to climate change and forecast impacts of climatic extreme events.

OCCR researchers involved in prominent law case

OCCR researchers involved in prominent law case

Several professors at the University of Bern and OCCR researchers are jointly filing a so-called Third Party Intervention in the case of KlimaSeniorinnen and Others v. Switzerland currently pending at the European Court of Human Rights. Along with two other climate cases, KlimaSeniorinnen was given priority status and moved to the Grand Chamber, which will set important precedents on whether and to what extent States are bound to take positive measures to protect people against the threats and harms of climate change.

In their lawsuit, the association KlimaSeniorinnen (Senior Women for Climate Protection) argues that Switzerland’s climate targets and measures are insufficient. To contribute to limiting global warming to a safe level, the Federal Government must adopt binding, and decisively stricter targets, and put in place more effective measures to achieve them. Previously, the lawsuit of the KlimaSeniorinnen had been rejected by all legal instances in Switzerland. The objective of this Third Party Intervention is to provide the Court an up-to-date scientific assessment of relevant points of contention, including on climate change and epidemiological evidence on the affectedness of elderly females to it, and thereby assist the Court in reaching its judgment. Read the story in the University of Bern’s web journal “uniaktuell”.

OCCR work highlighted at Dies academicus

Two OCCR projects were prominently mentioned under the heading “Highlights 2022” at the Dies academicus, the annual ceremony at which the University of Bern celebrates its foundation in 1834. Urban Climate Bern, the research on urban heat, as well as the tool “Flood dynamics” on extreme floods developed at the Mobiliar Lab for Natural Risks. In addition, OCCR researchers Ana Vicedo (Climate Change and Health group) and Moritz Burger (Climatology group) were the protagonists of a video on current high profile research created for the Dies. Watch the video.

Well received media releases

Well received media releases

"Alpine farming promotes plant diversity" reads the title of a media release (in German) on an international study in which OCCR member Christoph Schwörer (Paleoecology group) played a major role. Using data from a small mountain lake in the Bernese Oberland, the publication shows that today's high diversity of plant communities and species in parts of the Alpine landscape can also be attributed to human activities and interventions.

The media release was particularly well received by the agricultural press. All media releases on studies by OCCR researchers.

Beyond Epica deep drilling campaign in Antarctica

Beyond Epica deep drilling campaign in Antarctica

The Little Dome C site in Antarctica has reopened for the second ice core drilling campaign of the international research project Beyond Epica oldest ice of which the OCCR group Past Climate and Biogeochemical Studies on Ice Cores is a partner. OCCR members Markus Grimmer and Florian Krauss are part of the of the 15-person expedition team. They are stationed on Concordia, where the cores from Little Dome C are brought.

There Markus and Florian perform the first measurement on the complete core (dielectric profiling) and then cut the core into an archive piece that remains on Concordia and a sample piece that is brought to Europe at -50 °C. The special horizontal saw used for this task was developed in Bern and is a beautiful example of precision engineering by the University of Bern.

New International Global Atmosphere Watch project

The Atmospheric Processes and Radiometry group has successfully solicited a GAW project. The international Global Atmosphere Watch programme (GAW) is a partnership of over 100 countries worldwide and monitors the composition of the atmosphere. The new project called “The Swiss H2O Hub: High-quality water vapor measurements from ground to space” is a joint project with EMPA, ETH Zurich and MeteoSwiss. Measurement campaigns in Switzerland will be conducted to derive H2O profiles from ground to space by combining lidar and two balloon-borne instruments, complemented by radiosondes in Payerne and a microwave radiometer in Zimmerwald.

Positive Tipping Points

"uniaktuell", the web journal of the University of Bern, recently dedicated an article to the research by Lukas Fesenfeld (Policy Analysis and Environmental Governance group). The article focuses on the concept of "Positive Tipping Points", which is still little known to the public. Read the article.

Hendrik Vogel awarded SNF Sinergia grant

Hendrik Vogel (Sedimentary Geochemistry group) is the PI of a project which has been awarded an SNSF Sinergia grant. The project is entitled: “Deep biosphere-geosphere interactions at the top of the world (DIGESTED): An interdisciplinary approach to interpret a Myr climate record from Lake Nam Co, Tibetan Plateau”.

SNSF Synergia Grants are highly coveted and are endowed with approx. 3 Million Swiss Francs. DIGESTED is a multidisciplinary project: It combines combines expertise from the geosciences with those from environmental physics and microbiology to better understand climate dynamics influencing the monsoon and westerly circulation systems. It also explores the response of the deep biosphere to climate and tectonically driven changes in sediment composition. The project is highly collaborative with co-PIs from the University Lausanne, Eawag and the Univiversity Greifswald in Germany as well as additional project partners and collaborators from Switzerland and abroad.

Vincent Lam’s SNSF professorship extended

The SNSF professorship of Vincent Lam (PI Philosophy of science perspectives on the climate challenge group) has been extended for another two years till the end of 2024. The focus of Vincent’s project Epistemology of Climate Change is on epistemic and methodological issues related to extreme event attribution and climate tipping points.

Johannes Sutter and Ana Vicedo receive SNSF Starting Grant

Johannes Sutter (Past Climate and Biogeochemical Studies on Ice Cores group) has been awarded an SNSF Starting Grant. His project "Charting Antarctic Ice Sheet evolution via the ice sheet’s internal stratigraphy" is one of the winners among 445 applications submitted.
