Marine heatwaves are threatening ecosystems
15 August 2018
Marine heatwaves can irreversibly damage ecosystems and, therefore, also present a threat to fishing. As a team led by OCCR memberThomas Frölicher showed in a study just published in the journal Nature, the number of marine heatwaves has increased dramatically in past decades. This trend will further intensify as a result of climate change.
Hot city summer
2 August 2018
A dense network to measure temperature in Bern provides a detailed three dimensional picture of this summer’s heatwave. OCCR researcher show that the differences between single points of measurement within the city of Bern as well as in its surroundings may differ up to 4 °C. This is an important piece of information to plan measures against heat stress.
Lessons about a future warmer world using data from the past
25 June 2018
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.
Top of Europe» for greenhouse gas measurements
18 June 2018
The research station at Jungfraujoch where the OCCR group „Environmental Isotopes and Gases“ plays a prominent role is at the top of Europe – and not only because of its unique location. Within the framework of the European research infrastructure „Integrated Carbon Observation System" (ICOS), the laboratory in the heart of the Alps is now officially certified. 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.

ERC Advanced Grant for Climate Reconstructions
18 April 2018
OCCR researcher Stefan Brönnimann has received a grant of 3 million Swiss francs from the European Research Council for the next five years. The goal of the funded 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 allows dynamical interpretations of past climate events. The project combines numerical modelling and mathematical techniques with historical documentary data and measurements, and dynamical analyses.

A thermometer for the oceans
4 January 2018
The average sea temperature is an essential parameter of the global climate – but it is very difficult to measure. At least until now, because an international team of researchers including OCCR scientists have now developed a novel method using the concentration of noble gases in the eternal ice. This allows conclusions to be drawn on the changes in sea temperature from the last ice age to the present day.
Surface Water Floods – an Underestimated Risk
23 November 2017
Half of all flood damages are caused by surface water floods. However, recent hazard maps do not take into account this process. On 23 November from 16:15 to 19:00, the Mobiliar Lab for Natural Risks and the OCCR organize a public event (in German) where different activities regarding research, modelling and mapping of surface water floods as well as prevention strategies will be discussed.

Prehistoric alpine farming in the Bernese Oberland
6 April 2017
The people in Switzerland were on the move in the High Alps and running alpine pastures 7,000 years ago and therefore much earlier than previously assumed. A study by the University of Bern that combines archaeological knowledge with findings from palaeoecology comes to this conclusion. Prehistoric finds from the Schnidejoch Pass played a crucial part in this.
OCCR study rehabilitates climate models
7 February 2017
With new methods of reconstruction, climate researchers of the Oeschger Centre have been able to demonstrate that some 9,000 to 5,000 years ago, the Mediterranean climate was considerably warmer than previous studies had suggested. Among other things, previous concerns regarding the reliability of climate models could thus be dispelled.

More greenhouse gases from the sea
12 February 2016
The ocean surrounding Antarctica, which oceanographers often refer to as the Southern Ocean, plays an important role in regulating the Earth’s climate evolution. It absorbs carbon dioxide (CO2) from the atmosphere on one hand, but releases natural carbon as well. How will this buffer work in the future? Will the Southern Ocean continue to help reduce greenhouse gases, or will it increasingly serve as a source of them? At the Oeschger Centre, several climate research teams are searching for answers.
