Climate game successfully crowdfunded

09/18/2013 - The crowdfunding campaign for a new edition of the climate board game KEEP COOL has been closed successfully. 353 supporters paid altogether more than 13,000 Euros into the platform Startnext. Thanks to its fans, the game will be available again for schools and universities, organisations and private players in November 2013.

Science meets music – the Staatskapelle Berlin at Telegrafenberg

09/13/2013 - Soloists from the Staatskapelle Berlin will come to Telegrafenberg Potsdam for a charity concert of a very special kind tonight to support an environmental protection project. The "orchestra of change” wants to break open old habits and that not only musically – the concert will take place in the dark of the unique atmosphere of the cupola of the “Great Refractor”. Host will be Hans Joachim Schellnhuber, Director of the Potsdam Institute for Climate Impact Research (PIK) who will accompany the evening with scientific insights. Under a huge astronomical telescope, the past will meet the present, the guests will hear works of Johann Sebastian Bach and modern composers like Eugène Ysaÿe, Daniel Schnyder and László Dubrovay.

Income more important for carbon footprint than metropolitan living

09/11/2013 - Socio-economic drivers like income, education, car ownership or household size seem to be much more important for the carbon footprint of local areas than geographic and infrastructural drivers, a study by Jan Minx from the Potsdam Institute for Climate Impact Research (PIK) and his colleagues shows. Using data from the United Kingdom, the scientists compared consumption-based carbon footprints of 434 municipalities across the country with territorial CO2 emission estimates and found that – whether rural or urban – the way of living makes the real difference.

"Energiewende": Cost Driver or Climate Rescuer?

08/30/2013 - One of the greatest challenges for the new federal government to be in office as of autumn is - independent of its political composition – the energy turnaround. In the target triangle of food security, efficiency and sustainability, tension is increasing. At the background meeting of the German Climate Consortium last week, the central question therefore was “Energiewende: Cost driver or climate rescuer? The answer: “So far neither nor” said Brigitte Knopf from the Potsdam Institute for Climate Impact Research. Together with Erik Gawel from the Helmholtz Centre for Environmental Research (UFZ), she answered questions from journalists.

Extreme events forcing global warming? Climate extremes and the carbon cycle

08/15/2013 – Extreme events like heat waves, droughts, heavy rain might not only occur more frequently due to climate change. They could also force global warming if terrestrial ecosystems release CO2 as a result of those extremes. An international team of researchers now analyzed the impacts of extremes on forests, bogs, grass landscapes and arable areas througout the world, among them scientists from the Potsdam Institute for Climate Impact Research (PIK). Terrestrial ecosystems absorb about 11 billion tons less carbon dioxide every year as the result of the extreme climate events than they could if the events did not occur, the researchers write in the renowned journal Nature. This is equivalent to approximately a third of global CO2 emissions per year.

Multifold increase in heat extremes by 2040

08/15/2013 - Extremes such as the severe heat wave last year in the US or the one 2010 in Russia are likely to be seen much more often in the near future. A few decades ago, they were practically absent. Today, due to man-made climate change monthly heat extremes in summer are already observed on 5 percent of the land area. This is projected to double by 2020 and quadruple by 2040, according to a study by scientists of the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid (UCM). A further increase of heat extremes in the second half of our century could be stopped if global greenhouse-gas emissions would be reduced substantially.

Identifying climate impact hotspots across sectors

07/02/2013 - One out of ten people on Earth is likely to live in a climate impact hotspot by the end of this century, if greenhouse gas emissions continue unabated. Many more are put at risk in a worst-case scenario of the combined impacts on crop yields, water availability, ecosystems, and health, according to a study now published online by the Proceedings of the National Academy of Sciences (PNAS). It identifies the Amazon region, the Mediterranean and East Africa as regions that might experience severe change in multiple sectors. The article is part of the outcome of the Intersectoral Impact Model Intercomparison Project (ISI-MIP) that will be featured in a special issue of PNAS later this year.

Policy advice for EU decision makers: Edenhofer chairs new Energy Platform

07/17/2013 - Ottmar Edenhofer, Deputy Director and Chief Economist of the Potsdam Institute for Climate Impact Research (PIK), is co-chairing a new Energy Platform by the European Council of Academies of Applied Sciences, Technologies and Engineering (Euro-CASE), an non-profit organisation of national academies from 21 European countries. Bringing together the combined expertise of the academies, the Euro-CASE Energy Platform will provide independent science based policy advice with a focus on a European perspective for policymakers like the Directorate-General for Climate Action which implements the EU Emissions Trading System or the EU Commissioner for Energy, Günther Oettinger.

Each degree of global warming might ultimately raise global sea levels by more than 2 meters

07/15/2013 - Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of the ocean and melting mountain glaciers are the most important factors causing sea-level change today, the Greenland and Antarctic ice sheets will be the dominant contributors within the next two millennia, according to the findings. Half of that rise might come from ice-loss in Antarctica which is currently contributing less than 10 percent to global sea-level rise.

Intense exchange with African experts

07/01/2013 - Two groups of high-level experts from Africa came to the Potsdam Institute for Climate Impact Research (PIK) for an intense exchange on pressing issues like changing precipitation patterns and water availability under unabated global warming. Most importantly, one delegation sought advice for designing the Pan African Institute of Water and Energy Sciences (PAUWES) at the Abou Bakr Belkaïd University in Tlemcen, Algeria - this institute is supposed to provide expertise for the whole continent. Before visiting PIK, the group met with the German Minister of Economic Development and Cooperation to officially announce financial support for the project.
