Hitze und Trockensommer in der Schweiz

Vor 75 Jahren erlebte die Schweiz einen Hitze- und Trockensommer, der den Menschen jahrzehntelang als «die grosse Dürre» in Erinnerung geblieben ist. Am Geographischen Institut der Universität Bern, in Zusammenarbeit mit MeteoSchweiz, ETH Zürich, Universität Zürich, Agroscope und WSL, ist zum Thema eine neue Broschüre (und ein kurzer Film) entstanden. Darin zeichnen Wissenschaftlerinnen und Wissenschaftler aus verschiedenen Blickwinkeln nach, wie es 1947 zu diesem Rekordsommer kam und fragen, was wir daraus für die Zukunft lernen können: Was sind Ursachen und Folgen von Hitze- und Trockensommern in der Schweiz? Unter welchen Konsequenzen litten vor 75 Jahren Natur und Mensch, und wie wirken sich Hitze und Dürre heute aus? Wie normal wird ein Rekordsommer wie 1947 im Schweizer Klima der Zukunft?

More floods in a warmer world

Palaeoclimate studies suggest that past flood-rich periods coincided with cool periods, while climate projections suggest that flood risk may increase in a warming world. A contradiction? A new paper by the climatology group addresses this question by partitioning atmospheric drivers of floods into circulation changes and water vapour changes. Frequent floods in Europe in the mid 19th and early 20th century, as well as the flood-poor period in the mid 20th century, were driven by changes in atmospheric circulation. Conversely, the recent increase in flood frequency was driven by an increase in water vapoour, which in turn is driven by increasing temperature.

Winters are 3°C warmer than pre-industrial

Temperature reconstructions for the cold season based on freezing and thawing data from rivers and the observation of plants show the extent of warming over the past 300 years. Reconstruction show that northern mid-latitudes have warmed by three degrees. The new data also allow a better analysis of climate mechanisms. Particularly, the point to the important role of snow cover. These are the results of a study by the Climatology Group published today in “Nature Communications”.

Poster Award for Angela-Maria Burgdorf

The Swiss Global Change Day is a fixed entry in the agenda of every climate researcher in Switzerland, not the least because of the poster awards given to young researchers. This year the Commission for Atmospheric Chemistry and Physics of the Swiss Academy of Science awarded the poster "The Written Path to the Past" of Angela-Maria Burgdorf. Congratulations!

Arktische Gletscher und Jetstream

Durch die starke Erwärmung der Arktis verlieren Gletscher in Nordkanada und auf Spitzbergen jährlich ca. 44 Milliarden Tonnen Eis. Inter-annuelle Variabilität dieser Eisschmelze wurde bisher durch starke Westwindströmungen dominiert. Nun hat ein Team aus internationalen Forschenden mit Beitrag der Universität Bern in der Fachzeitschrift Nature Climate Change den zunehmenden Einfluss von meridionalen Luftströmungen festgestellt: Verliert Spitzbergen sehr viel Eis, verliert Nordkanada weniger, und umgekehrt. Dieses Phänomen wurde bisher nur in der Theorie aufgezeigt. Das Signal in den Gletschern könnte eine erste Bestandsaufnahme sein für solche Konsequenzen der globalen Erwärmung, Konsequenzen die auch das Wetter in Mitteleuropa betreffen könnten. Zur Studie: https://www.nature.com/articles/s41558-021-01275-4

Das Klima der Kleinen Eiszeit

Was können wir aus den Klimaschwankungen der Kleinen Eiszeit über die Klimaerwärmung lernen? Welche Auswirkungen hatten die Klimaschwankungen auf die Gesellschaft? Und wie erforschen wir überhaupt das Klima der Kleinen Eiszeit? Die Doku "Als es zwei Grad kälter wurde" des Bayrischen Rundfunks macht sich auf eine Spurensuche - unter anderem im Oeschger Zentrum und der Gruppe für Klimatologie: https://www.br.de/radio/bayern2/programmkalender/sendung-3318038.html

New Project "FAIRNESS"

This week the COST Action FAIRNESS (FAIR network of micrometeorological measurements) was officially launched. It is based on the conviction that managing weather-induced agricultural losses, water use for irrigation, new invasive species and disease vectors, plant diseases and pests, urban energy consumption and other problems requires making better use of available micrometeorological data. The Action intends to build a micrometeorological knowledge share platformwith an inventory of available and quality proven micrometeorological in-situ data , recommendations for measurement and data management in order to meet FAIR principles and examples of rural and urban FAIR data sets. The platform will link across various stakeholder groups and is carried by a transboundary network of researchers from 25 European countries, including the climatology group of the University of Bern.

An ensemble reconstruction of global monthly sea surface temperature and sea ice concentration 1000–1849

Within the framework of PALAEO-RA, Eric Samakinwa and co-authors from the climatology group of the University of Bern present monthly resolved SST and SIC fields for the period 1000–1849, which is suitable as boundary conditions for AGCM simulations. The 50-member ensemble spatially complete dataset is based on an existing coarse resolution annual mean temperature reconstruction, augmented with intra-annual and sub-grid scale variability that is physically consistent with information from models, proxies, and observations. With this new, freely available dataset, published in the Nature journal Scientific Data, science will gain new insights from AGCM simulations driven by realistic and temporally varying ensemble boundary conditions.

Climate data mirror world history

The collaboration between climate scientists and historians has a long tradition. Work on historical measurements is a prime example how developments on the two disciplines can further stimulate the mutual benefit. Historian Chantal Camenisch and climatologist Stefan Brönnimann discuss their views in a NZZ article. Also non-scientists can contribute to gaining climate data. A recent Euronews feature with Stefan Brönnimann addresses the role of citizen science in climate research.
