Global food production at risk of simultaneous heat waves across breadbasket regions
09/12/2019 - Certain patterns in the jet stream encircling the Earth can bring simultaneous heatwaves to breadbasket regions responsible for up to a quarter of global food production. Particularly susceptible are Western North America, Western Europe, Western Russia and Ukraine. Extreme weather events of such extent can significantly harm food production and thus make prices soar. In recent years, major food price spikes were associated with social unrest.

Lancet Countdown: Forschungsbericht zu Klimawandel und Gesundheit
14.11.2019 - Bis zum Ende dieses Jahrhunderts sind jährlich bis zu fünf zusätzliche Hitzewellen in Norddeutschland und bis zu 30 in Süddeutschland zu erwarten, wenn wir mit dem Ausstoß von Treibhausgasen so weitermachen wie bisher. Damit einhergehender Hitzestress und hohe bodennahe Ozonkonzentrationen können schwerwiegende Folgen für die menschliche Gesundheit haben. Dazu zählen unter anderem Hitzschlag, Herzinfarkt und akutes Nierenversagen aufgrund von Flüssigkeitsmangel. Am stärksten gefährdet sind ältere Menschen, Säuglinge, Patienten mit chronischen Erkrankungen sowie Personen, die schwere körperliche Arbeit im Freien verrichten, etwa Bauarbeiter.

PIK and MCC deliver detailed assessment of German climate package
14/10/2019 - The climate protection programme adopted by the Federal Government last week, which is intended to limit greenhouse gas emissions especially in the transport and heating sectors, is unlikely to be sufficient to achieve the 2030 climate targets. Policymakers need to make four particular adjustments: first, they need to raise the level of ambition for the carbon price; second, they need to improve social balance; third, they need to develop further its integration with the EU level; and fourth, they need to introduce an effective monitoring process. This is the core message of a detailed assessment of the climate package, presented by the Berlin climate research institute MCC (Mercator Research Institute on Global Commons and Climate Change) and the Potsdam Institute for Climate Impact Research (PIK).

PIK and MCC contribute to Climate Policy Special Report for German government
12.07.2019 - The special report, which the German Chancellor received from the “Five Sages” of the German Council of Economic Experts today, is based to a significant extent on a comprehensive analysis by the Berlin climate research institute MCC (Mercator Research Institute on Global Commons and Climate Change) and the Potsdam Institute for Climate Impact Research (PIK). On Thursday, the so-called Climate Cabinet, with the leaders of the chancellery and six ministries, will discuss a fundamental realignment of climate mitigation measures based on the special report. MCC and PIK Director Ottmar Edenhofer and the Chairman of the Council of Experts, Christoph Schmidt, will present their proposals as scientific advisers at the meeting in the presence of the German Chancellor.

German coal phase-out could be in vain without CO2-pricing
04/06/2019 - It cannot be taken for granted that Germany’s plan to phase out coal by 2038 will actually decrease CO2 emissions on the European level. On the contrary, the phase-out could even increase emissions due to a complicated new mechanism in the European Emissions Trading Scheme, a team of researchers shows in a new analysis. To make sure the coal phase-out really helps stabilise the climate, it must be combined with a minimum price for CO2 or the cancellation of existing emission certificates.

Dutch royal couple visits Telegrafenberg
05/22/2019 - King Willem-Alexander and Queen Máxima of the Netherlands visited the Albert Einstein Science Park on Potsdam's Telegrafenberg during their stay in the State of Brandenburg today. In the presence of Brandenburgs Prime Minister Dietmar Woidke and Minister of Science Martina Münch, the Potsdam Institute for Climate Impact Research (PIK) and the GeoResearchCenter (GFZ) signed cooperation agreements with Vrije Universiteit Amsterdam and TU Delft. The agreements are on geothermal research and research on weather extremes.

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.

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.

Climate plan for Germany and Europe: Economists propose CO2 price reform
03.12.2018 - A few days ago the UN Environment Agency advocated an international green tax reform - now economists have presented a new concept for a CO2 price reform in Germany and Europe right before the start of the climate summit in Katowice, Poland. SPIEGEL magazine was reporting on this issue in advance this weekend. Christoph Schmidt, Chair of the German Council of Economic Experts from RWI Essen, Leibniz Institute for Economic Research, and Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), have jointly drafted the cornerstones for a market-based way out of coal. Climate-damaging CO2-emissions would need to become more expensive, while at the same time the electricity tax could be lowered. A socially just and efficient transition to a sustainable economy is possible, according to the professors, who both belong to the Leibniz Association. If, on the other hand, greenhouse gas emissions were not reduced, there would be the risk of economic climate damage of unprecedented proportions.
