More CO2 than ever before in 3 million years, shows unprecedented computer simulation
03/04/2019 - CO2 greenhouse gas amounts in the atmosphere are likely higher today than ever before in the past 3 million years. For the first time, a team of scientists succeeded to do a computer simulation that fits ocean floor sediment data of climate evolution over this period of time. Ice age onset, hence the start of the glacial cycles from cold to warm and back, the study reveals, was mainly triggered by a decrease of CO2-levels. Yet today, it is the increase of greenhouse gases due to the burning of fossil fuels that is fundamentally changing our planet, the analysis further confirms. Global mean temperatures never exceeded the preindustrial levels by more than 2 degrees Celsius in the past 3 million years, the study shows – while current climate policy inaction, if continued, would exceed the 2 degrees limit already in the next 50 years.

The living lab experiment "Climate-Neutral Living in Berlin" takes stock: Everyone can contribute to climate stabilization, but without politics it won’t succeed
31/01/2019 - "Climate-Neutral Living in Berlin" – for one year, more than 100 Berlin households have tried to shift to a more climate-friendly everyday life, from families with children, partners, flatmates to singles. In the living lab experiment headed by the Potsdam Institute for Climate Impact Research (PIK), households were reducing their climate footprint by an average of around 10 percent, even though they had, on average, already started the project 25 percent below the German average. The results of the project: in all sectors, from nutrition and consumption to electricity, heating and mobility, there is great potential for each and every one to reduce their CO2 emissions. But the experiment also shows where the limits of individual contributions to climate protection are, and where a political framework is necessary to set the stage for a more climate-friendly everyday life.

UN climate summit agrees on rulebook – yet more ambition is needed: PIK leaders at COP24 in „Heißzeit“ times
17.12.2018 - The Katowice UN climate summit’s results are “a relief” with regard to the agreed rulebook, according to the Directors of the Potsdam Institute for Climate Impact Research (PIK). However, the close to 200 states at COP24 failed to scale up ambitions for greenhouse gas emission reductions, say Johan Rockström and Ottmar Edenhofer. Concrete measures are urgently needed though since governments are steering Earth into a “Heißzeit”. This “hot age” has been investigated in scientific publications from PIK leaders, including Director Emeritus John Schellnhuber. The term “Heißzeit” has now been elected “word of the year 2018” in Germany.

Planetary Boundaries and Global Commons - managing risks and solutions
11.12.2018 - Weather extremes, food security, migration: people's livelihoods depend on climate stabilization. The joint side event of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC) at the UN climate summit COP24 highlighted how a safe operating space for humanity within Planetary Boundaries and the sustainable use of Global Commons like the atmosphere are key concepts combining natural and social sciences to safeguard our future. Based on these fundamental concepts, sound options for managing risks and solutions were explored by the new joint PIK leadership Johan Rockström and Ottmar Edenhofer.

A Greentech Race towards Climate Stabilization: European Expert Group Publishes Landmark Innovation Report
28.11.2018 - Zero-carbon solutions, i.e. technologies and lifestyles completely free of fossil-fuel use, must be the foci of European investments into research and innovation. Conventional low-emission options have very limited potential to contribute in time to avoiding dangerous global warming, an independent group of eminent experts concludes. By way of contrast, ambitious innovation programs can kick-start a greentech race to the top, while boosting the competitiveness of the European economies and securing our prosperity. The “High-Level Panel on Decarbonization Pathways” report is published today, together with the European Commission Communication Strategy for long-term EU greenhouse gas emission reductions, in the run-up to the UN climate summit (COP24) in Katowice, Poland.

Science and the state capital Potsdam become climate partners
11.11.2018 - Potsdam's mayor Jann Jakobs and researchers from severeal institutes in the state capital have aggred upon a "climate-partnership". Among the signatories is Ottmar Edenhofer, acting director of the Potsdam Institute for Climate Impact Research. The goal of the partnership: Until 2050 the city plans to bring its CO2 emissions to almost zero - in this way the municipality would make its contribution to the climate stabilization targets of the Paris Climate Agreement.

IPCC report on 1.5°C: Unprecedented transformation needed to reach climate targets
08/10/2018 - Limiting global warming to 1.5° Celsius would require rapid, far-reaching and unprecedented changes in all aspects of society, says a new detailed assessment by the Intergovernmental Panel on Climate Change (IPCC). Ninety-one authors and review editors from 40 countries were involved in preparing the report, among them Elmar Kriegler from the Potsdam Institute for Climate Impact Research (PIK) who is one of the lead authors for the key chapter on mitigation pathways. The Special Report on Global warming of 1.5°C will be an important scientific input into the UN climate summit in Poland in December and was prepared in response to an invitation from the United Nations Framework Convention on Climate Change when the historic Paris Agreement was adopted in 2015.

Overcoming barriers for climate policy: Short-term policies can bring long-term targets in reach
15.10.2018 - To make climate policy more stringent, a smart sequencing of measures is a promising option. An international team of researchers now proposes a framework for doing so using policy sequencing – experiences from Germany and California serve as examples. Specific policy options at early stages enable more ambitious policies at later stages by removing or relaxing barriers that prevented their implementation. This might be a usefull approach for for the design of long term policies such as the currently debated German coal phase out.
