2017/02/10 - This week, all scientists and staff of the Potsdam Institute for Climate Impact Research (PIK) gathered for their annual roadshow of scientific achievements and discussions of future projects. Packed with presentations and debates, PIK´s Research Days are an unequalled opportunity to share insights and shape the future course of the institute.
01/23/2017 - Some of the most distinguished international climate experts are gathering in Potsdam this week for a symposium of the Earth League, a self-organized initiative of leading researchers on global change. During two days, they will discuss how the Great Transformation towards sustainability can be brought about. The success of the Paris climate agreement aiming at completely decarbonizing our economies within a few decades is by no means ensured; fulfilling its objectives requires a ratcheting-up of ambitions through social, political and economic progress.
01/19/2017 - Some of the most important crops risk substantial damage from rising temperatures. To better assess how climate change caused by human greenhouse gas emissions will likely impact wheat, maize and soybean, an international team of scientists now ran an unprecedentedly comprehensive set of computer simulations of US crop yields. The simulations were shown to reproduce the observed strong reduction in past crop yields induced by high temperatures, thereby confirming that they capture one main mechanism for future projections. Importantly, the scientists find that increased irrigation can help to reduce the negative effects of global warming on crops – but this is possible only in regions where sufficient water is available. Eventually limiting global warming is needed to keep crop losses in check.
23/12/2016 - Groundwater has contributed greatly to increasing food security by ensuring water availability for irrigation at critical times. Today, 43 percent of global food production depends on groundwater use. However, water reserves are not endless, and climate change puts additional pressure on groundwater management. A new transdisciplinary and international research group on Water Management in the Future Earth Framework will address these challenges, co-chaired by Anne Biewald of the Potsdam Institute for Climate Impact Research (PIK). As part of the Sustainable Water Future Programme, several research groups will bring together the best international expertise to drive solutions to the world’s water problems.
12/19/2016 - Benchmarks to guide countries in ratcheting-up their ambition to remain well-below 2°C and pursue 1,5°C in an equitable manner are critical but not yet determined in the context of the Paris Agreement. A new study published in Nature Climate Change analyzes the national climate targets needed to meet the 1.5°C and 2°C goals according to five different equity principles, and how these compare with the current climate pledges.
16/12/2016 - The holiday season is in full swing and many enjoy the opportunity to feast – or to make new year resolutions for a healthier diet. What we eat is more than a private decision – the agriculture and land use sector is one of the central players in ambitious climate change mitigation efforts. Yet, mitigation policies in agriculture may conflict with food security. A team of scientists from the Potsdam Institute for Climate Impact Research analyzed the impacts on food prices under mitigation policies – targeting either incentives for producers or consumer preferences. They show that policy instruments to mitigate climate change with an educational approach to change food preferences can avoid unwanted impacts of climate change mitigation measures on food security.

Calibrating complex models: terminology, methods and implications for impact projections organized by Christopher Reyer
11/09/2016 - Researchers from the Potsdam Institute for Climate Impact Research (PIK) are attending the current UN climate summit COP22 in Marrakesch from November 7 to 18. Amongst other events, PIK Director Hans Joachim Schellnhuber will speak at a side-event of the German Advisory Council on Global Change on the science-policy dialogue to reach Paris targets. PIK chief economist Ottmar Edenhofer will discuss the potential of the Paris Agreement in a side event with colleagues from Arizona State University, Harvard Kennedy School and others.
08/25/2016 - Global warming could create substantial economic damage in agriculture, a new study conducted by a team of scientists of the Potsdam Institute for Climate Impact Research (PIK) finds. Around the globe, climate change threatens agricultural productivity, forcing up food prices. While financial gains and losses differ between consumers and producers across the regions, bottom line is that consumers in general will likely have to pay more for the same basket of food. As the additional expenditure for consumers outweighs producers’ gains, increasing net economic losses will occur in the agriculture and food sector towards the end of the century. However, economic losses could be limited to 0.3 percent of global GDP – depending on agricultural trade policies.
08/16/2016 - When hurricanes like Katrina in 2005 or Sandy in 2012 impact on highly populated regions they bring about tremendous damages. More than 50 percent of all weather-related economic losses on the globe are caused by damages due to tropical cyclones. Researchers from the Potsdam Institute for Climate Impact Research (PIK) now analyzed the magnitude of future hurricane losses in relation to economic growth. Showcasing the United States they found that financial losses per hurricane could triple by the end of the century in unmitigated climate change, while annual losses could on average rise by a factor of eight. Most importantly and contrary to prevalent opinion, they conclude that economic growth will not be able to counterbalance the increase in damage.
07/19/2016 - Flood-related losses can be expected to increase considerably in Germany as a result of climate change, a new study shows. Extreme events like the severe floods along the river Elbe have already illustrated the potentially devastating consequences of certain weather conditions such as severe rainfall events, when continuing intense rain can no longer be absorbed by the soil and water levels in the rivers rise. Without appropriate adaptation, flood-related damage of currently about 500 million euros a year could multiply in the future, the comprehensive expert analysis published in the journal Natural Hazards and Earth System Sciences highlights.
05/20/2016 - Migration is currently a no 1 issue in Germany as well as Europe – but what will future migration look like globally, in the age of climate risks? Where is environmental migration happening already today, and what can we learn from it? The Potsdam Institute for Climate Impact Research (PIK) teamed up with the International Organization for Migration (IOM) - the biggest intergovernmental institution in the field - for a media briefing in Berlin. Migration is mostly driven by a multitude of factors – be it political, social, demographic, economic, or by security concerns - and almost never by a single cause. At the same time, global environmental change, and specifically climate change caused by greenhouse gas emissions from burning fossil fuels, is an additional and potentially severe risk factor.
Young scientist from the Potsdam Institute for Climate Impact Research (PIK) discussed their working routines and career perspectives with regard to their doctorate. Once a year the “PhD-Day” offers the opportunity to meet up in the whole group of PhD candidates to share experiences, talk about research projects and train in science related skills. The focus of the current meeting was on possible career steps following the doctoral thesis.
01/28/2016 - Roughly two-thirds of observed climate change impacts related to atmospheric and ocean temperature over the past 40 years can be confidently attributed to human-generated greenhouse gas emissions, an international team of scientists found. For the impacts observed not just on regional but on continental scales, even three quarters are mainly due to our burning of burning fossil fuels. Evidence connecting changes in precipitation and their respective impacts to human influence is still weak, but is expected to grow.
01/27/2016 - The president of Leibniz Association, Matthias Kleiner, visited the Potsdam Institute for Climate Impact Research (PIK) for an exchange on current projects and developments. Among other topics the focus of the meetings was also on research strategies. Kleiner met with PIK Director Hans Joachim Schellnhuber as well as with the Chairs of PIK’s four research domains.
