Crash of seemingly stable social systems: new dynamics detected

Crash of seemingly stable social systems: new dynamics detected

09/30/2016 - From Facebook to international climate agreements like the Paris accord that is currently in the ratification process, the stability of complex social networks is still poorly understood. To better assess system crash likelihood, an international team of scientists now proposes a new mathematical system dynamics model. One key factor for system collapse is individual action based on local information, the study finds. When a member of the network - be it a person or a state - observes friends or allies to leave the system, it likely opts out as well. Small perturbations can hence have huge impacts.

Top scientists: Abandoning the Paris Agreement would harm America and the World

Top scientists: Abandoning the Paris Agreement would harm America and the World

09/23/2016 - In an unprecedented move, 375 renowned scientists including 30 Nobel Laureates have warned the US presidency candidates not to shun the Paris climate agreement. In an open letter published this week, the scholars emphasize that human-caused global warming including its negative impacts is “not a belief, it is a physical reality”. All signers are members of the eminent US National Academy of Sciences, including the director of the Potsdam Institute for Climate Impact Research, Hans Joachim Schellnhuber.

Extreme events and planetary waves: new index approach

Extreme events and planetary waves: new index approach

09/22/2016 - Both heat waves like 2010 in Russia or cold spells like 2014 in the US have a common feature – they appeared together with certain patterns of gigantic airstreams in the atmosphere. This so called jetstream circles around the globe in waves swinging up and down between the Tropics and the Arctic. These large meandering planetary waves can have huge impacts – the economic damages of the 2014 cold spell at the US east coast with record-breaking cold temperatures for instance were estimated up to 5 billion Dollars.

Climate impacts on amphibians and reptiles

Climate impacts on amphibians and reptiles

09/07/2016 - How does climate change affect amphibians and reptiles – animals whose body temperature depends directly on ambient temperature? A team of international scientists, involving the Potsdam Institute for Climate Impact Research (PIK) and WWF Germany, analyzed the peer reviewed literature on the subject of the past ten years – their findings were now published in Royal Society Open Science.

Edenhofer ranked amongst Germany’s top economists

Edenhofer ranked amongst Germany’s top economists

09/06/2016 - In a ranking of Germany’s “most influential economists”, Ottmar Edenhofer, chief economist of the Potsdam Institute for Climate Impact Research, was placed amongst the top researchers in the field. The grouping published by the renowned daily ‘Frankfurter Allgemeine Zeitung’ (FAZ) is based on data on the scientific, political and media impact of the individual researchers. Edenhofer, who also directs the Mercator Research Institute on Global Commons and Climate Change and is a Professor at Technische Universität Berlin, is the only economist with a focus on climate who scored this high in the ranking.

New interactive climate spirals online

New interactive climate spirals online

07/27/2016 - Global-mean temperatures are breaking one record after the other since instrumental observations began. Driven by burning of fossil fuels and deforestation, carbon dioxide concentrations have also soared to unprecedented levels. In fact, today's CO2 concentrations are higher than they have ever been over the last 800 thousand years. Scientists from the Potsdam Institute for Climate Impact Research (PIK) and the University of Melbourne now put all these elements together to provide a set of new interactive Climate Spiral visualizations.

Sustainable cities: Researchers discuss urban complexity

Sustainable cities: Researchers discuss urban complexity

07/26/2016 - From mega-cities like Shanghai or New York to the small town around the corner: International researchers gathered in Hanover to discuss “Cities as complex systems – structure, scaling and economics”. The symposium brought together physicists, economists, geographers, and urban planners to explore the underlying mechanisms of the efficiency of our cities. Currently more than half of the world’s population lives in urban areas, a proportion that is expected to increase considerably, reaching over 90 percent of the global population by the end of this century. While about two thirds of global greenhouse-gas emissions are caused by urbanites, at the same time cities are hit particularly hard by the impacts of climate change.

Successful early forecasting of Indian Monsoon

Successful early forecasting of Indian Monsoon

2016/07/14 - A novel approach of unprecedentedly early forecasting of the Indian Monsoon proved to be successful. The new methodology - developed at the Potsdam Institute for Climate Impact Research (PIK) - correctly predicted this year’s monsoon onset over central India and met great interest by both Indian academics and stakeholders, including the Indian Meteorological Department (IMD). The accurate long-range monsoon forecasting is of critical importance for millions of farmers in India. [Please find an UPDATE on the withdrawal below.]

Paris pledges need boost to keep warming well below 2°C

Paris pledges need boost to keep warming well below 2°C

06/30/2016 - The individual country pledges to reduce greenhouse gases made for the Paris agreement need to be strengthened in order to limit future climate change to well below 2°C. A new analysis by an international team of scientists illustrates that the current Paris pledges would lead to global temperature rise of 2.6 to 3.1°C by the end of the century. In fact, the entire carbon budget for limiting warming to below 2°C might have been emitted by 2030, according to the study published in the journal Nature.

PIK ranked among top climate think tanks worldwide

PIK ranked among top climate think tanks worldwide

06/27/2016 - The Potsdam Institute for Climate Impact Research (PIK) belongs to the best climate think tanks worldwide, the new ICCG Climate Think Tank Ranking shows. The assessment by the International Center for Climate Governance analyzed 240 cutting-edge institutions working in the field of climate change economics and policy. Based on a solid quantitative methodology and analytical data, the ICCG lists non-university affiliated think tanks in an absolute and a standardized ranking - the latter based on an institute's output in relation to the number of its researchers. In both competitions, PIK ranks fourth best global climate think tank.

Extreme weather events linked to stalling of planetary waves

Extreme weather events linked to stalling of planetary waves

06/11/2016 - Many extreme weather events in the Northern hemisphere have recently been accompanied by a stalling of huge airstreams high up in the atmosphere that normally circle our planet, taking the form of gigantic waves swinging up and down between the Tropics and the Arctic. Looking into the events of the summers three and four years ago, a new study by a team of scientists from the Potsdam Institute for Climate Impact Research finds that in fact a majority of extremes go with observed disturbances of the so-called planetary waves, adding evidence to the assumption that this connection might be of key importance.

Energy independence policies will not save the climate

Energy independence policies will not save the climate

06/10/2016 - Reducing energy imports and mitigating climate change are often portrayed as complementary. However, new research published in the journal Nature Energy shows that while ambitious climate policies would lower energy imports, energy independence would not bring significant climate benefits. Co-benefits of climate policies are of key importance for decision-makers choices, the authors highlight.

Health, energy and extreme events in a changing climate

Health, energy and extreme events in a changing climate

06/07/2016 - Floods, droughts, blackouts of power networks – the potential for risks that can be linked directly or indirectly to public health grows with a changing climate. In a now published special issue of the European Physical Journal, scientists of the Potsdam Institute for Climate Impact Research (PIK) and other institutions analyze the complex interactions of public health, energy production and climate change. They shed light on the linkages, and also present new methods how these interrelations of different sectors can be further examined.
