SPECIAL: Coal phase-out: Announcing CO2-pricing triggers divestment

Photo Schellnhuber presents 10 Must-Knows on Climate at COP23Putting the Paris climate agreement into practice will trigger opposed reactions by investors on the one hand and fossil fuel owners on the other hand. It has been feared that the anticipation of strong CO2 reduction policies might – a ‘green paradox’ – drive up these emissions: before the regulations kick in, fossil fuel owners might accelerate their resource extraction to maximize profits. Yet at the same time, investors might stop putting their money into coal power plants as they can expect their assets to become stranded. Now for the first time a study investigates both effects that to date have been discussed only separately. On balance, divestment beats the green paradox if substantial carbon pricing is credibly announced, a team of energy economists finds. Consequently, overall CO2 emissions would be effectively reduced. Read more...

From power grids to heartbeat: Using mathematics to restore rhythm

From power grids to heartbeat: Using mathematics to restore rhythm

07/15/2015 - When a rhythm stalls, the effect can be fatal – in a power grid it can mean a blackout, and in the human heart even death. An international team of scientists has now developed a new approach for revoking these undesired quenching states. They use an advanced mathematical methodology, building on complex networks analysis, and demonstrate it in experiments with chemical reactions. This could one day help to stabilize the flow of electricity in power grids challenged by the variable input from renewable energy sources. Future research could apply it to other complex networks, including processes within body cells and even the human cardiovascular system.

Edenhofer speaking to finance ministers at OECD green tax conference

07/15/2015 - Strategies for environmental tax reform and growth were at the focus of a talk given by Ottmar Edenhofer, chief economist at the Potsdam Institute for Climate Impact Research, at a high-level conference in the run-up of the world climate summit in Paris COP21 later this year. The recent meeting was a joint initiative by the Organisation for Economic Co-operation and Development (OECD), the International Monetary Fund (IMF), the Worldbank and others. It was attended by Finance and Environment Ministers, senior policy makers and experts from more than 90 countries, including China and Indonesia, Mexico and Egypt, Sweden and Portugal.

New super-computer for climate science ranks among world’s top 400

New super-computer for climate science ranks among world’s top 400

07/13/2015 - The new high-performance computer at the Potsdam Institute for Climate Impact Research ranks among the 400 fastest world-wide. This was announced today at the beginning of the International Supercomputing Conference in Frankfurt, Germany. The machine is able to do 212 trillion calculations per second – so called Teraflops. This allows simulations of the complex interactions between atmosphere, oceans, land and ice-sheets to a much larger extent than was hitherto possible on site. The computer’s waste heat is used – environmentally-friendly – to heat the new PIK research building.

Our Common Future Under Climate Change

Our Common Future Under Climate Change

07/10/2015 - This week, thousands of climate and social scientists as well as policy experts have met for the “Our Common Future under Climate Change” conference at the UNESCO headquarters in Paris, among them a large number of experts from the Potsdam Institute for Climate Impact Research (PIK). It has been the biggest gathering of high-ranking scientists paving the way for COP21 in December, laying out the state of science for fact-based decision-making.

Record-breaking heavy rainfall events increased under global warming

Record-breaking heavy rainfall events increased under global warming

07/08/2015 - Heavy rainfall events setting ever new records have been increasing strikingly in the past thirty years. While before 1980, multi-decadal fluctuations in extreme rainfall events are explained by natural variability, a team of scientists of the Potsdam Institute for Climate Impact Research detected a clear upward trend in the past few decades towards more unprecedented daily rainfall events. They find the worldwide increase to be consistent with rising global temperatures which are caused by greenhouse-gas emissions from burning fossil fuels. Short-term torrential rains can lead to high-impact floodings.

Waste works: new Artist in Residence

Waste works: new Artist in Residence

06/29/2015 - One ton of recycled plastic boards pose as surrogate books, filling library shelves – this is just one example of Dan Peterman’s works. The Chicago-based art professor from the University of Illinois is this summer’s Artist in Residence at the Potsdam Institute for Climate Impact research (PIK). With long-term commitment to the socially oriented and environmentally conscious art, he has widely exhibited in the United States and internationally. Now he’s seeking the exchange with climate scientists, from Antarctica experts to energy economists. On 30 June, he will give a talk at the Kunstraum, Schiffbauergasse Potsdam.

Schellnhuber appointed to Pontifical Academy of Sciences

06/26/2015 - The Pontifical Academy of Sciences, one of the most renowned around the globe, has selected climate scientist John Schellnhuber to become a member. Pope Francis himself nominated him last week. Schellnhuber, a professor of physics and director of the Potsdam Institute for Climate Impact Research, participated in a number of the Academy’s workshops on the sustainability challenge before, and he was the only scientist to speak at the presentation of the environmental encyclical “Laudato Si” in the Vatican.
