“Humanity at risk “: climate scientist Schellnhuber speaks at the Vatican

06/18/2015 - Pope Francis’ much anticipated encyclical “Laudato Si” on inequality and the environment mirrors not only religious insights but also the findings of climate science. “Not the poor but the wealthy are putting our planet, and ultimately humanity, at risk,” said Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research (PIK), at the presentation of the encyclical in the Vatican today. “Those who profited least from the exploitation of fossil fuels and contributed least to greenhouse-gas emissions are hit hardest by global warming impacts, unless we strongly reduce emissions.” Schellnhuber is the only scientist who has been invited to speak, alongside Cardinal Peter Turkson.

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.

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.

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.

“The Great Urban Transformation“: Nobel Laureates call on cities to tackle sustainability challenge

04/25/2015 - Cities around the globe need to re-invent themselves if they want to be a safe home for generations to come. Nobel Laureates call upon cities to tackle the dual challenge of population growth and climate change and seize the opportunity to lead the transition to sustainability. National and internationally agreed greenhouse-gas reduction targets need to guide and support local action. The distinguished scientists signed a memorandum this week in Hong Kong at the end of the three-day Nobel Laureates Symposium on Global Sustainability, convened for the first time in Asia. The Symposium was co-hosted by the Potsdam Institute for Climate Impact Research and the Asia Society Hong Kong Center.

What would it take to limit climate change to 1.5°C?

05/21/2015 - A new study analyzes the required climate policy actions and targets in order to limit future global temperature rise to less than 1.5 degrees Celsius by 2100. This level is supported by more than 100 countries worldwide, including those most vulnerable to climate change, as a safer goal than the currently agreed international aim of 2 degrees Celsius – an aim which would already imply substantial greenhouse-gas reductions. Hence the interest for scrutinizing the very low end of greenhouse-gas stabilization scenarios.

“Developing our cities, preserving our planet”: Nobel Laureates gather for the first time in Asia

23.04.2015 - Nobel Laureates across the world and across disciplines this week are gathering in Hong Kong to elevate the debate on climate change to a new level and to feed into the world climate summit in Paris later this year. For the first time, the Nobel Laureates are meeting in Asia for the symposium, “4C: Changing Climate, Changing Cities”. Cities are key to addressing the challenge of climate change which, if unabated, might result in a 4°C rise in mean temperature by the end of this century. Participants of the symposium include Nobel Prize winners Yuan T. Lee (Chemistry, 1986) from Taiwan, Brian Schmidt (Physics, 2011) from Australia, and James A. Mirrlees from the United Kingdom (Economics, 2006), complemented by international renowned experts such as K.S.

Climate change in Antarctica: Natural temperature variability underestimated - Cold spell superimposes man-made warming

04/16/2015 - The Antarctic ice sheet is one of the tipping elements in the climate system and hence of vital importance for our planet’s future under man-made climate change. Even a partial melting of the enormous ice masses of Antarctica would raise sea-levels substantially. Therefore it is of utmost importance to provide sound knowledge on the extent of anthropogenic warming of the ice-covered continent. A new analysis by German physicists shows that the uncertainties in the temperature trends over Antarctica are larger than previously estimated. “So far it seemed there were hardly any major natural temperature fluctuations in Antarctica, so almost every rise in temperature was attributed to human influence,” says Armin Bunde of Justus-Liebig-Universität Gießen (JLU). “Global warming as a result of our greenhouse gas emissions from burning fossil fuels is a fact. However, the human influence on the warming of West Antarctica is much smaller than previously thought. The warming of East Antarctica up to now can even be explained by natural variability alone.” The results of their study are now published in the journal Climate Dynamics.
