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.
Shortly ago, several PIK-studies showed: the sea level is now rising faster than in the last 28 centuries, that with unconstrained emissions, it will continue to rise about 50 to 130 cm in the next century, and even massive geoengineering approaches would not be able to prevent this. PIK-scientist Anders Levermann comments on the results in a synopsis about the danger of sea level rise due to climate change. Source: BBC (UK), 11.04.2016.
A new PIK-study shows: By 2050, about a tenth of global greenhouse-gas emissions from agriculture could be traced back to food waste. PIK-scientist Prajal Pradhan explains how reducing it would offer the chance to ensure food security as well as it could help mitigate dangerous climate change.

Recent February's spike in global temperatures was the biggest departure from the norm in 137 years of records. "We are running out of time to avoid a 2-degree world", PIK-scientist Stefan Rahmstorf comments. Source: The Sydney Morning Herald (Australia), 25.03.2016
Global temperature records have recently been broken again and again, last February was 1.35°C warmer than average. PIK-scientist Stefan Rahmstorf states that this is not a surprise and that "time has almost run out to get emissions down". Source: The Guardian, 17.03.2016
Global February Temperatures showed a disturbing upward spike. PIK-scientist Stefan Rahmstorf and Steve Sherwood from the University of New South Wales explain how global warming and El Niño combine to produce the record warmth. Source: The Conversation (UK), 16.03.2016.
In this February, the Earth's overall surface temperature was about 1.35°C warmer than the average temperature for the month. Do we face a climate emergency? PIK-scientist Stefan Rahmstorf and other experts comment on the record-breaking temperature. Source: The Guardian (UK), 14.03.2016.
Could Geo-Engineering help us counter future sea-level rise? A new PIK-study shows: the sea-level rise is too big to be pumped away. PIK-scientist Anders Levermann explains the results and their meaning for the future discussion on climate change. Source: The Washington Post (USA), 10.03.2016.
The number of record-breaking rainfalls increases worldwide - related to global warming. Already in 2015, a team of PIK-scientists around Jascha Lehmann and Dim Coumou figured out an innovative method and found, that at least every tenth rainfall record of the last thirty years stands in direct correlation with climate change.

Damages from extreme events like floods are even more relevant than the mean sea level itself when it comes to the costs of climate impacts for coastal regions. A new PIK-study now provides a method to quantify monetary losses from coastal floods under sea-level rise. Source: The Guardian (UK), 02.03.2016.
During past millennia sea-level has never risen as fast as during the last century, as a new PIK-study shows. PIK-scientist Stefan Rahmstorf explains, why the study is for sea level what the famous 'hockey stick' diagram was for global temperature. Source: The New York Times (USA), 23.02.2016.
