IPCC Co-Chair calls for re-thinking of policy assessments

07/04/2014 – When the Working Group III (WGIII) contribution to the IPCC’s Fifth Assessment Report, the most comprehensive assessment of climate change mitigation options to date, was accepted by IPCC member governments in April this year, governments could not agree on parts of its Summary for Policymakers during the approval process. As a result the material was cut. In the current edition of the journal Science, a Co-Chair and leading authors of Working Group III re-visit the approval session and comment on deleted content and the strengths and weaknesses of the IPCC process in a series of articles.

CO2 is fertilizing hidden hunger

06/27/2014 - While CO2 emissions from fossil fuels are a driver of climate change with potentially negative impacts on crop yields, they are also a fertilizer for the plants. However, this effect comes at the expense of a deterioration of the current nutritional value of food, new research by the Harvard School of Public Health and others shows. This might lead to hidden hunger, researchers of the Potsdam Institute for Climate Impact Research argue in a recent commentary published in Nature Climate Change. Diets with sufficient calorie content could come with an insufficient supply of vitamins and minerals.

High-ranking Chinese researchers visit PIK

06/17/2014 - A high-level delegation from China was brought up to speed on a variety of topics - from rising sea levels to the problems of the EU Emissions Trading Scheme (ETS) - during a visit to the Potsdam Institute for Climate Impact Research (PIK). The delegation was led by Du Xiangwan, Director of the China Expert Panel on Climate Change (EPCC), which advises the Chinese State Council. Other acclaimed scholars from renowned Chinese institutions such as Tsinghua University were also present, including He Jiankun, Zhou Dadi and Chao Qingchen. The delegation also included Tian Chengchuan, Yuan Jiashuang and Zhu Songli, all of whom hold notable positions in key advisory bodies such as the National Development and Reform Commission (NRDC). China is currently discussing its future carbon emission targets. Due to the country’s critical impact on the global climate and international climate policy, the outcome of this deliberation has been the subject of intense speculation and anticipation.

Capturing CO2 emissions needed to meet climate targets

06/26/2014 - Technologies that are discussed controversially today may be needed to keep the future risks and costs of climate change in check. Combining the production of energy from fossil fuels and biomass with capturing and storing the CO2 they emit (CCS) can be key to achieving current climate policy objectives such as limiting the rise of the global mean temperature to below 2 degrees Celsius. This is shown by the most comprehensive study to date on technology strategies to combat climate change, published in a special issue of the journal Climatic Change. It is based on the analysis of 18 computer models by an international team of scientists under the roof of the Stanford Energy Modelling Forum (EMF 27).

Air pollution and climate policies: workshop in Beijing

06/20/2014 – Policies aimed at countering climate change can have important co-benefits in terms of reduced air pollution and hence on public health. Now for the first time, a so-called multi model comparison was used by researchers to scrutinize this interplay using a whole set of different computer simulations of economic and social processes. Their findings, including a robust win-win-scenario, were recently at the center of a workshop in smoggy Beijing. It was hosted by the Energy Research Institute of the Chinese National Development and Reform Commission (ERI-NDRC), which is one of the most important players in the field, whereas the research project itself is coordinated by the Fondazione Eni Enrico Mattei (FEEM). The Potsdam Institute for Climate Impact Research (PIK) is part of the steering group and led a major analysis of 2 degree scenarios that was conducted by the project.

First Potsdam Summer School to focus on Arctic climate change

06/13/2014 - "Arctic in the Anthropocene" – the present geological era which has been dominated by humankind – will be the main focus of the Potsdam Summer School. During the two-week program, 40 selected young international scientists and experts will exchange ideas on a wide range of issues, including the melting of Greenland’s ice sheets and marine biology. In northern regions of the world, the effects of climate change have already become quite apparent. In collaboration with the Alfred Wegner Institute for Polar and Marine Research (AWI), the German Research Centre for Geosciences (GFZ), the Institute for Advanced Sustainability Studies (IASS) and the University of Potsdam, the Potsdam Institute for Climate Impact Research (PIK) will be organizing the event, which will be held from June 23 to July 4, 2014, and is likely to be continued on an annual basis in the future.

World Bank hosts IPCC report presentation

06/12/2014 - Dealing with climate change is an exercise of risk management, two leading authors of the recent Intergovernmental Panel on Climate Change (IPCC) reports said at a major World Bank event in Washington D.C. last week. Chris Field of the Carnegie Institution's Department of Global Ecology at Stanford University, co-chair of the IPCC working group on climate change impacts, adaptation and vulnerability addressed about 600 people both in the room and online, together with Ottmar Edenhofer of the Potsdam Institute for Climate Impact Research, co-chair of the IPCC working group on climate change mitigation.

"Excellent researcher, warm manners": farewell symposium for Gerstengarbe

06/02/2014 - One of the founding members and key figures of the Potsdam Institute for Climate Impact Research (PIK) was honored with a farewell symposium last week. Friedrich-Wilhelm Gerstengarbe, assistant director of the institute and co-chair of its research domain Climate Impacts and Vulnerabilities, embarked on his retirement. About 200 peers, colleagues, and friends, gathered to debate an issue dear to Gerstengarbe, a meteorologist who always cared about the practical implications of his findings: 'Climate and Climate Impact Research between Science and Society'.

German Federal Environment Minister Hendricks Visits PIK

06/03/2014 – German Environment Minister Barbara Hendricks was briefed by scientists of the Postdam Institute for Climate Impact Research (PIK) on current research developments. The minister, who has only held this office for several months, discussed recent findings and their impact on politics with PIK Director Hans Joachim Schellnhuber as well as other researchers. The focus of the talks was on the difficulties encountered in implementing climate policies.

China's reported plans to introduce absolute carbon cap

06/05/2014 - Today, media outlets have reported that China plans to introduce an absolute carbon cap. Yesterday, the US announced plans to reduce greenhouse gas emissions. The EU is currently discussing its climate targets for 2030.
