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.

At the COP20 Conference in Paris in 2015, emissions reductions in order to keep global warming "well below 2°C" were negotiated. Whilst the agreement now enters into force, leading climate experts, among them PIK-scientists Stefan Rahmstorf and Bill Hare, comment on current climate policies and tell their expectations for the future.

The 16-month streak of record high average temperatures finally came to an end with September, which was slightly cooler than last year. PIK-scientist Stefan Rahmstorf and other climate experts explain, that global warming, nevertheless, is going on. Source: Vancouver Sun (Canada), 19.10.2016.
To limit global warming below 2°C, a long-term reduction of greenhouse gas emissions is necessary. PIK-scientist Gunnar Luderer explains, why therefore "the energy mix in 2050 will have to look fundamentally different from the one we have today." Source: CNBC (USA), 10.10.2016.
In this year of unprecedented temperature levels, also other records concerning heatwaves, floodings, wildfires and hurricanes tumble around the world. Alongside other climate experts, PIK-scientist Stefan Rahmstorf comments on these extremes: "I hope people realise that global warming is not something down the road, but it is here now and is affecting us now."

"The only way of stabilising global warming at well below 2˚C is to urgently decrease global emissions and create a fossil fuel-free world economy no later than 2040-2060", say PIK-director John Schellnhuber and Johan Rockström, director of the Stockholm Resilience Center, in their recent op-ed article.

Mercator Climate Lecture 2016: "The World in 2050 - Towards Sustainable Development and Deep Decarbonization"
More than 1000 people attended the 2016 Mercator Climate Lecture "The World in 2050 - Towards Sustainable Development and Deep Decarbonization" in Berlin on Wednesday. Top US-economist Jeffrey D. Sachs, Director of the Earth Institute at Columbia University and Special Advisor on Sustainable Development for the United Nations, gave a much-applauded keynote. This was followed by an intense discussion with Ottmar Edenhofer, Chief Economist at the Potsdam Institute for Climate Impact Research (PIK) and Professor at Technische Universität (TU) Berlin. The lecture is a joint project by Stiftung Mercator, Technische Universität Berlin, and PIK. Source: TU Berlin, 01.06.2016.
Migration is mostly driven by a multitude of factors - and almost never by a single cause. At the same time, global environmental change, and specifically climate change, is an additional and potentially severe risk factor. PIK-scientist Hermann Lotze-Campen and Mariam Traore Chazalnoel from the International Institute for Migration speak in a video statement about the topic.
A new PIK-study compared the impacts of 1.5°C and 2.0°C of further global warming by means of several different indicators. The PIK-scientists Jacob Schewe and Carl Schleussner explain, why half a degree matters and why different regions show different vulnerabilities for climate change impacts.

1.5°C or 2.0°C - two goals for preventing further global warming were mentioned in the Paris Agreement, that is now to be signed. A new PIK-study analyzed different indicators of climate impacts and showed that the two goals would make significant differences. PIK-scientists Jacob Schewe and Carl Schleussner explain the results. Source: Science Magazine (USA), 21.04.2016.
A new PIK-study introduces a novel monsoon prediction method based on a network analysis of regional weather data. The heavy summer rains are of vital importance for millions of farmers. The PIK-scientists Veronika Stolbova, Elena Surovyatkina and Jürgen Kurths explain the relevance of the new method. Source: The Financial Express (India), 21.04.2016.
Already in 2013, a PIK-study explored the interconnections between the so-called Rossby-Waves and local surface weather. A new PIK-study now revealed, that the balkan floods in 2014 were triggered by these mechanisms. 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. 18.04.2016.
