As mentioned previously, the Oeschger Centre will prepare a review Report (self-evaluation) in 2021. This report will review the achievements of the past four years and propose potential new avenues for further development of the OCCR research portfolio. For this purpose, a working group has been established which is composed of all the OCCR Research Group leaders and of representatives of PostDocs, PhD and MSc students at the OCCR. The working group will meet on 27 January 2021 for a one-day retreat. After this, all OCCR members will be invited to comment on the review proposal.
The OCCR is a scientific partner of Phänomena, a huge science show to be held in Zurich in 2022. The first edition of Phänomena in 1984 is still very much in the mind of people who visited it due to its novel way to present scientific phenomena and to present science as an adventure. Phänomena 22 will feature climate and climate change as one of its major sections.
The OCCR has been asked to coordinate the climate part of the show and is currently involved in workshops with the organizers and designers of the exhibition.
The OCCR’s Prehistory Archeology group has received SNFS funding for two projects starting in 2021. The project XRONOS – Open Access Database for absolute chronological archaeological information was granted 320'000 CHF, the project Mobility, Vulnerability and Resilience of Middle European Neolithic Societies at the end of the 4th millenium BC receives 785'000 CHF. The XRONOS project aims to compile and manage radiocarbon and dendrochronological data in a worldwide unique database. This will enable a multitude of transdisciplinary research projects on population dynamics, human-environmental dependencies and thus fundamental transformations in the European past. The Mobility project will combine qualitative and quantitative methods of archaeology, archaeometry and climate studies in order to provide a precise chronology and information on the history of settlement in wetland sites in France, Germany and Switzerland during the Neolithic transition during the 4th–3rd millennia BC.
The pilot project for Large Eddy Simulation (LSE) (see Oeschger-News September 2020) is well under way. A contract with the private company Meteotest has been signed and a number of experimental studies to show the feasibility and substantiate potential fields of application of LSE have now been launched. In simple terms, LSE is a weather model which allows the simulation of circulation on a small scale (the bottom of mountain valleys, urban canyons etc.). At the OCCR, this new tool – based on a PALM model – might be used in the fields of urban climatology, climate and human health as well as climate risks, extreme events and other climate impacts.
The University of Bern, represented by the OCCR, is a founding partner of the International Universities Climate Alliance (IUCA). This group of around 50 leading universities wants to provide a strong and respected international voice on matters related to climate change science, impacts, mitigation and adaptation. The IUCA has published an open letter to the G20 leaders who met on 21 and 22 November 2020 in Riad. The closing part of this declaration reads: “We still have a window of time to make the necessary transition to a carbon-neutral economy, we strongly encourage world leaders to ensure that all COVID stimulus measures maintain their countries’ commitments under the Paris Agreement and work toward a net-zero emission plan.”
As mentioned in the last edition of this newsletter, the OCCR is the new partner of Girls on Ice Switzerland. A series of mini-workshops at schools will be conducted in the framework of this project. The workshops aim to enhance the dialogue on the scientific process and related facts about climate change impacts on glaciers, in particular. It builds on the experiences gained with the Girls on Ice project. Past participants will lead a post-expedition mini-workshop at their school, with the support of one of the science instructors. The peer-to-peer communication as well as the interactive structure of the mini-workshops opens the floor for science-based discussions among young students supported by science-ambassadors. Teachers interested in hosting a workshop at their school are welcome to contact the project team via email@example.com.
OCCR members Chantal Camenisch and Heli Huhtamaa (Environmental History and Historical Climatology group) were part of the editing team of the latest issue of the Past Global Changes Magazine which presents the state of research in the field of historical climatology. Its articles examine different regions of the world and review innovative methodological approaches, recent scientific results, and analyses of new source materials.
A strength of historical climatology is the recovery of precisely located and dated information on climate and weather before the modern instrumental record.
The OCCR’s Mobiliar Lab for Natural Risks has just published the latest issue of its biannual newsletter (in German). Topics featured include a study on why object protection measures against floods have not been implemented to a greater extent, and a survey on the importance of risk apprehension by the general public when managing flood risks.
The OCCR’s Community ecology group runs a large field experiment in Münchenbuchsee (near Bern) which investigates the mechanisms by which nitrogen enrichment affects ecosystem functioning. The so-called PaNDiv experiment was extensively featured in the 3sat TV show Nano (in German, see 21:20). “It was quite an interesting experience working with the presenter to make the segment and trying to explain our research in accessible terms”, said Eric Allan, the project leader.
A study by OCCR member Aurea Chiaia-Hernandez (Lake Sediments and Paleolimnology group) on plant protection products in the sediments of lake Münchenbuchsee close to Bern was the topic of a recent media release issued by the University of Bern.
Read up about these and many more appearances of OCCR members in the media in the Press Coverage and Press Releases sections of the OCCR website.
Honouring the 50-year anniversary of the BernClim observation network at the Institute of Geography, Stefan Brönnimann and This Rutishauser (Climatology group) have edited a collection of articles for a broader audience. A number of authors from the OCCR, among others, show how climate change leads to changes in the timing of seasonal events of plants such as blooming as well as changes in the seasonality of snow and hydrological systems, agriculture, forestry, frost events and grape harvest dates of the last centuries.
The brochure «Klimawandel und Jahreszeiten» is available in German for download from Geographica Bernensia and in print upon request from the Climatology Group.
The next OCCR Plenary Meeting Spring 2021 will take place on 18 February 2021, 14 – 17 h. Save the date! Details on time and location are to be announced.
A number of OCCR events that had to be postponed due to the Corona crisis have been rescheduled: The Workshop on Compound Weather and Climate Events will take place 12 - 15 January 2021 (online-format only).

The Swiss Climate Summer School 2021 is entitled “Vegetation, Land surface and Climate Interactions" and will take place from 29 August to 3 September in Ticino, Southern Switzerland. The call for the Summer School has not been launched yet, OCCR Postdocs and PhDs will be directly informed when to register. Remember that the OCCR covers the costs for the Summer School for all Postdocs and all the PhDs enrolled in the Graduate School. The Summer School 2022 will be on Extreme Events.
The OCCR’s Mobiliar Lab for Natural Risks traditionally holds a public event in November. Due to the corona crisis, this year’s event had to be cancelled. Instead, the Mobiliar Lab has posted a series of short videos on hochwasserrisiko.ch. These films show how extensive flood damage to buildings is today and how the risk will evolve in the future. Moreover, the videos explain how the so-called damage simulator (‘Schadensimulator’) created by the Mobiliar Lab can be used to interpret hazard maps and to establish the possible extent of damage to buildings. Interested parties are invited to discuss methodological questions and possible applications of the damage simulator with the project team (firstname.lastname@example.org).
The OCCR Young Researchers Meeting 2021 is planned to take place in Aeschi bei Spiez on 10 and 11 June. A call for the meeting will be launched in February 2021. Save the date for now.
Charlotte Blattner, an OCCR associate, works on her habilitation on climate law at the University of Bern. Together with colleagues from Johns Hopkins University (Baltimore, USA) and the University of Wageningen (NL), she has recently organized a series of seminars on animals, climate change and global health. The event involved leading experts from around the world and aimed to inspire an in-depth conversation – and actions – regarding animals, climate change, and global health. All the six webinars have been recorded and can be viewed on https://animalsclimatehealth.com.
The next Swiss Global Change Day will take place on 13 April 2021. Speakers include OCCR member Bettina Schaefli (Hydrology group).

Thomas Frölicher (Ocean modelling group) is part of major international project. In September 2020, 36 organisations from 13 different countries launched AtlantECO, an ambitious research project funded by the European Union to explore the Atlantic Ocean from pole to pole.
The project will map new and existing knowledge about the microscopic organisms that inhabit rivers, coastal waters, the open ocean, marine sediments and the atmosphere, as well as those found on plastic litter. This microbiome-based study of climate change, adaptation and resilience aims to predict the future of Atlantic marine ecosystem services. Inspired by medical research that combines next generation genetic, imaging and environmental approaches, AtlantECO will develop diagnostic tools and metrics to assess and predict changes in the health of the Atlantic Ocean.
Frerk Pöppelmeier is a Postdoc with the Earth System Modelling – Climate Dynamics group. He is working towards a better understanding of the Atlantic circulation and says: “In our area of study, data alone will not get us anywhere. To get a little closer to the truth, you have to link measurement results to models”. At the OCCR, Frerk Pöppelmeier has found exactly the expertise in climate modelling that he needed to advance his research.
