A workshop in Bern in April 2017, which was funded by PAGES and the OCCR on the Past Global Changes integrated activity "Warmer Worlds", has now led to a publication in Nature Geoscience. "Warmer Worlds" uses paleoclimate evidence to assess a future warming. The assessment of past warm periods by an international team of 59 scientists from 17 nations, shows that in response to the warming, ecosystems and climate zones will spatially shift, and on millennial time scales, ice sheets will substantially shrink. The compiled evidence from the past suggests that, even with a global warming limited to within 2°C above preindustrial levels, as aimed at in the Paris Agreement, climate zones and ecosystems will shift, rapid polar warming may release additional greenhouse gases, and sea-level will rise by several meters over several thousand years. These observations show that many current climate models designed to project changes within this century may underestimate longer-term changes. (Read the University of Bern’s press release on the publication.)
One of the coordinators of "Warmer Worlds" is Hubertus Fischer (Past Climate and Biogeochemical Studies on Ice Cores group). He was prominently featured in a story on the new findings by "Tagesschau", the primetime news program of Swiss Public TV (SRF1).
The Mobiliar Lab for Natural Risks aims to better inform authorities and the public about the risks associated with flooding. For this reason, it’s creating an interactive online database of images illustrating floods: the "Collective Flood Memory". The project website publishes flood photos from all over Switzerland. The collection should continue to grow with the help of the general public, which is called upon to submit its own pictures on the interactive website at www.ueberschwemmungsgedaechtnis.ch.
The OCCR research group Environmental Isotopes and Gases plays a prominent role at the High-Alpine Research Station Jungfraujoch. The research station is now officially certified within the framework of the European research infrastructure «Integrated Carbon Observation System» (ICOS). ICOS provides data to better understand the global carbon cycle and how human activities affect it. The backbone of ICOS is a network of stations that have to meet the highest quality standards.

The Mobiliar Lab for Natural Risks has started with the construction of the Swiss Hail Network, a fully automatic measuring network. The 80 sensors are installed in the three regions of Switzerland with the highest probability of hailstorm occurrence. A number of twenty-five sensors will initially be installed in the Napf Region, with a further 15 to follow in this region, 25 in the Jura and 15 sensors in Southern Ticino by spring 2020. For the first time, this network will record the impact energy, the grain size, the distribution and the precise time of hailstorms. In doing so, it will create a data set to increase the understanding of hailstorms. The new insights will improve the monitoring, the measurement, the warning, as well as the short-term forecasting and the climatology of hailstorms. The project aims to record as many hail incidents as possible in order to reduce hail damage in the long term. The Hail Network will be operated over a period of eight years.
Container3 was a touring exhibition on climate research, presented and organized by the OCCR in 2017. The exhibition is prominently featured in the University of Bern’s annual report 2017. The show, which was installed in sea containers, comprised audio visual and interactive presentations on the work of six OCCR research and toured city districts of Bern. The exhibition was realized in cooperation with the City of Bern, which presented topics related to energy and mobility in its own containers.

The next OCCR Plenary Meeting will take place on Friday, 14 September 2018 (14 – 17 h), details on location and program will follow shortly. The next but one Plenary Meeting is scheduled for Thursday, 14 February 2019 (14 – 17 h). Save the dates!
On 25 – 27 April 2018, the OCCR group Ocean Modelling organized a workshop within the WCRP (World Climate Research Programme) Grand Challenge "Carbon feedbacks in the climate system". A core objective of this so called "area of emphasis in scientific research" is to advance the understanding of feedbacks between the climate and the carbon cycle. At the workshop in Bern, an extended carbon cycle feedback framework was developed and tested against available CMIP5 model simulations, and will be tested against CMIP6 simulations at a later stage. A position paper on "An extended climate-carbon cycle feedback framework to analyse Earth System Models projections" was outlined as a result of the very successful meeting.
On 18 – 21 June, an international conference and workshop on early instrumental meteorological was hosted by Stefan Brönnimman (Climatology group) and Christian Rohr (Environmental History and Historical Climatology group). The conference attracted more than 50 scientists, further participants and speakers joined the conference remotely. The presentations covered all continents (the participants came from 23 different countries) and revealed not only how many meteorological records have been digitized in recent years, but also how much more could potentially become available. The goal of the subsequent workshop then was to start the process of creating a global inventory of all potential climate records prior to 1850. This inventory should include not only the already digitized records, but also all the ones we know of, but have not yet been digitized or even located in archives. Such an inventory will help to prioritize data rescue work and eventually should form the basis for extending observation-based large-scale climate data products back to the 18th century.
On 14 – 15 June 2018, the OCCR’s traditional Young Researchers Meeting took place in Aeschi in the Bernese Oberland. 45 PhD students from the University of Bern, ETH Zürich and other institutions were very actively engaged in discussions on the controversial topic "Climate action for Climate Scientists – How (not) to communicate, advocate and take action for climate". Questions raised included: Scientists have warned about drastic effects of climate change for decades, to no avail so far. Is this true? Have we failed in communicating our results? How to best move society towards the 2-°C goal? What would efficient climate advocacy be? Should we focus on technological rather than societal changes? And what is our role as (young) climate scientists? The discussion was fueled by keynote lectures and workshops. Among the speakers were OCCR president Thomas Stocker, Fritz Sager, a professor of Political Science at the University of Bern and Jacques Mirenowicz, a former neuroscientist turned climate activist (Artisans de la transitions, Fribourg).
On 1 – 2 October 2018, a workshop called "Methods and interdisciplinary communication in historical climatology" will take palace at the University of Bern. This meeting is the first event within in the framework of the PAGES Working Group Climate Reconstruction and Impacts from the Archives of Societies (CRIAS). One of the four leaders of this Working Group is Chantal Camenisch from the OCCR’s Environmental History and Historical Climatology group (read a profile story on Chantal entitled "Double challenge for the intrepid"). The aim of the 1st CRIAS workshop is to evaluate and integrate different methodological approaches from historical climatology over all historical periods and geographical regions, and to identify and disseminate best practices in the field. Additionally, it aims to promote interdisciplinary collaboration between historical climatologists and (paleo)climatologists, especially by identifying ways to effectively share historical climatology data and combine historical and paleoclimate information in highresolution reconstructions. Programme and registration.
Martin Grosjean, the OCCR’s director, couldn’t hide his emotions when he bade farewell to Margret Möhl. "Now, the moment I was dreading since we started working together in 2001 has arrived", he said during a reception for Margret in the vineyards high above lake Biel. Indeed, Margret, a trained geographer, was the soul of first the NCCR Climate’s and then the OCCR’s management office. She remained ever calm even in turbulent times and run our institution’s budget with meticulous care. We will miss Margret’s interest in all the OCCR’s work and her uplifting mood. If you are a bicycle enthusiast as she is, you might easily meet her on a grand tour through Europe one of these days fully equipped with a tent and cooking gear.
Stefan Brönnimann (Climatology group) receives a grant of 3 million Swiss francs from the European Research Council for the next five years. The goal of the project PALAEO-RA is to produce a comprehensive reconstruction of global climate of the past six centuries, a palaeo-reanalysis. The reconstruction will provide globally complete, three dimensional monthly fields of many variables and thus allow dynamical interpretations of past climate events. The project combines numerical modelling and mathematical techniques with historical documentary data and measurements, and dynamical analyses. Read a story entitled "The Climate Detective" on Stefan’s successful bid published in Berner Zeitung.
Oliver Heiri (Aquatic Paleoecology group) has received the IPA (International Paleolimnology Association) Outstanding Service Award at the 14th International Paleolimnology Symposium, which took place in Stockholm from 18 to 21 June 2018.
