SPECIAL: Summer extremes of 2018 linked to stalled giant waves in jet stream

Arctic Sea IceRecord breaking heatwaves and droughts in North America and Western Europe, torrential rainfalls and floods in South-East Europe and Japan - the summer of 2018 brought a series of extreme weather events that occurred almost simultaneously around the Northern Hemisphere in June and July. These extremes had something in common, a new study by an international team of climate researchers now finds: the events were connected by a newly identified pattern of the jet stream encircling the Earth. The jet stream formed a stalled wave pattern in the atmosphere which made weather conditions more persistent and thus extreme in the affected regions. The same pattern also occurred during European heat waves in 2015, 2006 and 2003, which rank among the most extreme heatwaves ever recorded. In recent years, the scientists observed a clear increase of these patterns. Read more...

The living lab experiment "Climate-Neutral Living in Berlin" takes stock: Everyone can contribute to climate stabilization, but without politics it won’t succeed

The living lab experiment "Climate-Neutral Living in Berlin" takes stock: Everyone can contribute to climate stabilization, but without politics it won’t succeed

31/01/2019 - "Climate-Neutral Living in Berlin" – for one year, more than 100 Berlin households have tried to shift to a more climate-friendly everyday life, from families with children, partners, flatmates to singles. In the living lab experiment headed by the Potsdam Institute for Climate Impact Research (PIK), households were reducing their climate footprint by an average of around 10 percent, even though they had, on average, already started the project 25 percent below the German average. The results of the project: in all sectors, from nutrition and consumption to electricity, heating and mobility, there is great potential for each and every one to reduce their CO2 emissions. But the experiment also shows where the limits of individual contributions to climate protection are, and where a political framework is necessary to set the stage for a more climate-friendly everyday life.

Rainfall extremes are connected across continents: Nature study

Rainfall extremes are connected across continents: Nature study

31.01.2019 - Extreme rainfall events in one city or region are connected to the same kind of events thousands of kilometers away, an international team of experts finds in a study now published in one of the world’s leading scientific journals, Nature. They discovered a global connection pattern of extreme rainfall – this could eventually improve weather forecasts and hence help to limit damages and protect people. Extreme rainfall events are on the rise due to human-caused climate change, which makes the study even more relevant. The researchers developed a new method rooted in complex systems science to analyze satellite data. The revealed extreme rainfall patterns are likely linked to giant airflows known as jetstreams that circle the globe high up in the atmosphere, forming huge waves between the Equator and the Poles.

Brandenburg's Research Minister Münch welcomes Edenhofer and Rockström as new PIK Directors

28/01/2019 - Climate economist Ottmar Edenhofer and earth resilience researcher Johan Rockström are officially appointed as new scientific directors of the Potsdam Institute for Climate Impact Research (PIK). Science and Research Minister of Germany's Federal State Brandenburg Martina Münch acknowledged the two scientists as a "strong team for future tasks in climate and environment politics" and the Potsdam Institute for Climate Impact Research as one of the world's most influential and high-profile think tanks.

Germany phases out coal to help stabilize our climate

Germany phases out coal to help stabilize our climate

27/01/2019 - The Coal Commission established by the German government recommends to phase out coal - with an end date in the 2030s. It is highly likely that political decision-makers will act upon this recommendation now and indeed put an end-date to coal-use in the world's fourth biggest economy Germany. The Coal Commission consisted of representatives from industry, trade unions, environmental associations, and academia. Experts from the Potsdam Institute for Climate Impact Research (PIK) were closely involved in the difficult negotiations. Physicist Hans Joachim Schellnhuber, PIK's Director Emeritus, was a member of the Commission. PIK's acting Director and chief economist Ottmar Edenhofer had been invited to provide advice to the committee.
