PIK in the Media
All around the world, demonstrations for science take place on April 22nd - under the title "March for Science". PIK-scientist Stefan Rahmstorf explains in an interview, why the research community goes out to the streets - and which problems science is facing at the moment. Video in Russian language.

More than 400 researchers and representatives from politics, businesses and society are discussing the concept of Planetary Boundaries this week in Berlin. "The concept of Planetary Boundaries describes on a scientific basis what the limits are that we should adhere to with changes of the planet so that we do not enter dangerous terrain", explains PIK-scientist Wolfgang Lucht.

Already in 2013, a PIK-study explored the connections between the so-called Rossby-Waves and local surface weather. A new PIK-study delivers further evidence for the human fingerprint on these links. PIK-scientist Kai Kornhuber explains in an illustrated video, how extreme weather events are influenced by the giant airstreams - and how climate change affects them.

Past PIK-studies have shown that a weaker jet stream makes the weather more persistent and promotes prolonged heat waves. New research provides further evidence, that the conditions for such weather extremes are favourably influenced by human-made climate change. PIK-scientists Stefan Rahmstorf and Kai Kornhuber comment on their results. Source: The Guardian (UK), 27.03.2017.
On the eve of this year's Earth hour, international experts propose a roadmap strategy for achieving net-zero emissions by mid-century. "Short-termism has been a problem for all the 25 years I have been involved in climate negotiations," says PIK-director John Schellnhuber. The "carbon law" links short-term targets to long-term goals - by halving emissions every ten years. Source: The Guardian (UK), 23.03.2017.
A PIK-study found out: climate disasters like heat-waves or droughts potentially enhance the risk of armed conflict. While such disasters might be increased through climate change, they can trigger the outbreak of conflicts particularly in ethnically fractionalized societies. In a video feature, PIK-scientist Jonathan Donges explains the study results. Source: Latest Thinking (Germany), 21.03.2017.
If we want to reach the goals of the Paris Agreement, urgent efforts have to be made: the combustion engine has to be phased out, coal plants must be shut down and concrete and steel for construction need to be replaced. PIK-director John Schellnhuber explains in an interview, why scientists have to leave their ivory towers to be part of the solution. Source: Deutsche Welle (Germany), 15.03.2017.
Using a novel complex network analysis of water fluxes, a new PIK-study found: future rainfall reductions intensified through climate change could push the Amazon region into a vicious dieback circle. However, a great variety of tree species in a forest patch can strengthen the chance of survival. PIK-scientist Delphine Clara Zemp comments on the study results. Text in Spanish.

Stefan Rahmstorf is co-chair of the PIK Research Domain Earth System Analysis and Professor of Physics of the Oceans at the University of Potsdam. In an interview, he speaks about his scientific career, introduces his current research topics, and emphasizes the dangers of global warming. Source: Earth101 YouTube Channel (Iceland), 03.03.2017.
Climate change has a major impact on food production and security - as the effects of recent heatwaves in Australia have shown once more. PIK-scientist Christin Meyer with Elisabeth Vogel and Richard Eckard from the University of Melbourne explain, how important mitigation and adaptation measures are.

In a last year's study, PIK-scientists investigated the global potential to produce more food with the same amount of water - by optimizing rain use and irrigation. PIK-scientist Jonas Jaegermeyr explains in a commentary, why water scarcity is a societal phenomenon, and how it could be countered. Source: The Mark News (Canada), 27.02.2017.
The ambitions of the new US-administration in terms of climate protection still remain unclear. Worrying Donald Trump risks creating "an atmosphere of conflict", PIK-scientist Stefan Rahmstorf emphasizes the need of international co-operation to avoid dangerous global warming.

As public communication concerning climate change has already been restrained by the Trump administration, the scientific community is worried, that climate data itself could also become restricted from public access. PIK-scientist Anders Levermann explains the global importance of these data from institutions like NASA or NOAA. Source: Public Radio International (USA), 26.01.2017.
A new PIK-study found, that in the US, yield losses of 20 percent for wheat, 40 percent for soybean and almost 50 percent for maize are possible by 2100 - without efficient emission reductions. The effects went far beyond the US, one of the largest crop exporters. PIK-scientist Bernhard Schauberger comments on the results. Source: The Independent (UK), 19.01.2017.
As plants can react to a changing climate in complicated and even contradictory ways, research on the effects of Climate Change on Agriculture is tricky. A new PIK study found, that some of the most important crops risk substantial damage from rising temperatures. PIK-scientist Bernhard Schauberger explains the study results.

Whilst delegates from 196 states gathered at the UN Climate Change Conference in Marrakech, Donald Trump was elected the President of the United States. How will this interfere with the Paris agreement? PIK-director John Schellnhuber explains the urgency of effective climate policies and interprets Albert Einstein's view on climate protection.

2015 already, a PIK-study revealed hints about a weakening of the "Gulf Stream" called circulation system in the Atlantic Ocean, which had effects on marine eco-systems, the global sea-level and the weather in North America and Europe. In a new simulation by US-scientists, the current seems to be even more vulnerable. PIK-scientist Stefan Rahmstorf comments. Source: Washington Post (USA), 04.01.2017.
Depuis novembre, la couverture mondiale de glace de mer accuse une perte de plus de trois millions de kilomètres carrés par rapport à la moyenne 1981-2010, selon les données du National Snow and Ice Data Center (NSIDC) américain. PIK-scientifique Anders Levermann commente: "C’est une situation époustouflante." Source: Le Monde (France), 29.12.2016.
As humanity faces unprecedented climate risks, "for both public and private actors, the time to act is now", conclude PIK-director John Schellnhuber, Christian Thimann from AXA and Axel Weber from UBS. In a joint commentary, they explain, how the Climate-Change Transition could be financed. Source: Project Syndicate (seated in Czech Republic), 24.11.2016.
NASA's Earth Science Division makes significant contributions to global efforts to monitor and counter global warming. Ending NASA's Earth Observatory Mission through the Trump administration "would seriously impair our ability to see the big planetary picture", criticizes PIK-director John Schellnhuber among other climate researchers.
