SPECIAL: IPCC report on 1,5°C: Unprecedented transformation needed to reach climate targets

Arctic Sea IceLimiting 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.

PIK Research Days: “Keep digging in your pockets”

PIK Research Days: “Keep digging in your pockets”

02/23/2018 - Scientists and staff of the Potsdam Institute for Climate Impact Research (PIK) gathered this week for their annual roadshow of scientific achievements and discussions of future projects. Climate negotiations, climate migration, public health, sea-level legacy, jet streams, ice losses at Antarctica, carbon pricing – these were just some of the topics presented by PIK’s four research domains. This year’s research days focused in particular on the upcoming 1.5°C IPCC special report as well as on global change, big data and digitalization.

Social and Natural science together: New Co-Directors to lead the Potsdam Institute for Climate Impact Research

Social and Natural science together: New Co-Directors to lead the Potsdam Institute for Climate Impact Research

23/02/2018 - The Potsdam Institute for Climate Impact Research (PIK) is reinventing itself – appointing a twin leadership bringing together natural sciences and social sciences stronger than ever. In late September, the German climate economist Ottmar Edenhofer and the Swedish Earth system scientist Johan Rockström will become directors of the internationally renowned institute which is a member of the Leibniz Association. This was decided on Friday by the institute's Board of Trustees, headed by the Brandenburg Ministry of Science, Research and Culture and the German Federal Ministry of Education and Research. The retirement of the founding director Hans Joachim Schellnhuber this autumn after a quarter of a century as the head of the institute marks the beginning of a new era in Potsdam.

Sea-level legacy: 20cm more rise by 2300 for each 5-year delay in peaking emissions

Sea-level legacy: 20cm more rise by 2300 for each 5-year delay in peaking emissions

02/20/2018 - Peaking global CO2 emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2°C. A study now published in the journal Nature Communications analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement. Their central projections indicate global sea-level rise between 0.7m and 1.2m until 2300 with Paris put fully into practice. As emissions in the second half of this century are already outlined by the Paris goals, the variations in greenhouse-gas emissions before 2050 will be the major leverage for future sea levels. The researchers find that each five year delay in peaking global CO2 emissions will likely increase median sea-level rise estimates for 2300 by 20 centimeters.

PIK ranked as the top climate think tank worldwide

14/02/2018 - The Potsdam Institute for Climate Impact Research (PIK) is the world’s most influential environmental think tank, a new ranking shows. For the ninth year in a row, PIK has been ranked among the top think tanks in the world working on environmental policy. The "Global Go To Think Tank Index Report 2017" that has just been published by the University of Pennsylvania, altogether considered more than 6,500 institutions across the globe.

Reports of coal’s terminal decline are premature

Reports of coal’s terminal decline are premature

02/07/2018 - While less new coal-fired power plants are now being built in China and India, the planned expansion in the use of coal in fast-growing emerging economies, such as Turkey, Indonesia and Vietnam, will in part cancel out the reduction. Only if the countries of the world actively counteract this trend, they can achieve the climate goals agreed in the Paris Agreement. These are the results of the study “Reports of coal’s terminal decline may be exaggerated,” authored by researchers from the Potsdam Institute on Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), published in the journal Environmental Research Letters

Potsdam-China and back: "When climate projections return home"

02/05/2018 - China's Guanting region is threatened by water scarcity - how water and land can be used sustainably was explored over several years by a German-Chinese team headed by the Potsdam Institute for Climate Impact Research (PIK). Now the scientists published a book on their findings. The researchers applied computer simulations on climate change and water cycles in Brandenburg to the Guanting region. They thereby gained valuable new methodological insights for refining their models - and now bring this back to Germany: a learning process across continents.

National Academy of Sciences Leopoldina appoints Edenhofer

National Academy of Sciences Leopoldina appoints Edenhofer

01/31/2018 - Ottmar Edenhofer, Chief Economist at the Potsdam Institute for Climate Impact Research, was elected member of the Leopoldina. The honouring is a special recognition of his scientific achievements and his personality, said Leopoldina President Jörg Hacker about Edenhofer, who is also Director of the Mercator Research Institute on Global Commons (MCC) and Professor of Economics of Climate Change at TU Berlin. The selection of a member for the German National Academy of Sciences Leopoldina follows strict standards and requires a broad agreement of the Extended Presidium.
