Federal Research Minister visits PIK

01/09/2023 - The Federal Minister of Education and Research Bettina Stark-Watzinger has visited the Potsdam Institute for Climate Impact Research (PIK). She spoke for almost two hours with climate economist and PIK Director Ottmar Edenhofer, as well as with Administrative Director Bettina Hörstrup and Gunnar Luderer from the Copernicus research project ARIADNE on energy transition policy. Topics included the federal government's hydrogen strategy and research into economic models for extracting CO2 from the air and storing it underground, as well as research into energy systems.

Climate risk insurance can effectively mitigate economic losses

01/04/2023 - Global warming is expected to lead to an accumulation of particularly intense hurricanes in the United States. This may substantially increase the economic losses caused by these storms. Better insurance could effectively mitigate the climate change-induced increase in economic losses. This is shown in a new study by the Potsdam Institute for Climate Impact Research examining the effectiveness of climate risk insurance in the US.

Carbon dioxide removal should receive additional financial support

12/20/2022 - Cleaning up greenhouse gases after they have been emitted should be incentivized by subsidies. New evidence from an economic analysis considering international markets suggests an important reason why subsidies should be higher than the price put on carbon emissions to incentivize their reduction. In a first-of-its-kind study, researchers analyze policies for removing carbon dioxide from the atmosphere and storing it underground or in products. The suggested different pricing is not due to technological challenges, but linked to an economic effect called leakage.

Finding equity in climate mitigation finance: new study in 'Science'

11/18/2022- Considerations of equity in directing global financial flows for regional climate mitigation investments are critically important. It is in the leading journal 'Science' that team of researchers led by the International Institute for Applied Systems Analysis (IIASA) and including the Potsdam Institute for Climate Impact Research (PIK) published a new study to help inform climate policy. The researchers explored how global investments could be divided among the countries in the world. The team applied a systematic approach with different equity and fairness considerations and estimated the “fair” financial flows between regions.

Potsdam researchers amongst top 1% most cited worldwide

11/14/2022 - For the fifth year in a row, researchers from the Potsdam Institute for Climate Impact Research (PIK) are among the top 1 percent of the globally most scientifically influential authors. The renowned "Highly Cited" ranking is published once a year by Clarivate Analytics' science platform Web of Science. The ranking is based on the number of times researchers are cited in other academics' works - one of the most important indicators of scientific relevance. Twelve PIK researchers are listed, just like last year, including the institute's directors, and from all research departments.

Green hydrogen: Short-term scarcity, long-term uncertainty

08/09/2022 - Green hydrogen from renewable electricity and derived e-fuels are uniquely valuable for achieving climate neutrality. They can replace fossil fuels in industry or long-distance transport where direct electrification is infeasible. However, even if production capacities grow as fast as wind and solar power, the growth-rate champions, green hydrogen supply remains scarce in the short-term and uncertain in the long term, a new analysis published in the journal Nature Energy shows.

Living in timber cities could avoid emissions – without using farmland for wood production

08/30/2022 - Housing a growing population in homes made out of wood instead of conventional steel and concrete could avoid more than 100 billion tons of emissions of the greenhouse gas CO2 until 2100, a new study by the Potsdam Institute for Climate Impact Research shows. These are about 10 percent of the remaining carbon budget for the 2°C climate target. Besides the harvest from natural forests, newly established timber plantations are required for supplying construction wood. While this does not interfere with food production, a loss of biodiversity may occur if not carefully managed, according to the scientists. The study is the first to analyze the impacts of a large-scale transition to timber cities on land use, land-use change emissions, and long-term carbon storage in harvested wood products.

Fighting poverty and protecting the environment can only work together: Policy paper by the Potsdam Institute for the German Environment Ministry

06/02/2022 - A decent living for all people and better protection of nature and climate aren’t conflicting targets, a new scientific analysis highlights. Development goals such as reduced poverty and inequality, better health and education, and a secure supply of food and energy on the one hand interact closely with stabilizing the climate and preserving biodiversity on the other. Only together can these goals be achieved, shows a report by the Potsdam Institute for Climate Impact Research (PIK) for the German Environment Ministry on the occasion of the Stockholm+50 summit which is starting today.

Climate policy: How to protect emissions trading from excessive financial speculation

12/15/2021 - CO2 emissions trading – a key element of EU climate policy – can be protected from distortions driven by financial speculators, a new report shows. The price for CO2 emissions allowances in the EU cap-and-trade scheme has almost tripled in the course of this year, and is now subject to unprecedented volatility levels. Financial speculation is increasingly blamed for this price rally, but evidence is lacking whether this can actually endanger the functioning of the trading system for the most relevant greenhouse gas. The researchers propose tools to detect speculation, evidence a substantial risk from a new breed of investors, and suggest improvements for market oversight.

Reducing tropical cyclone impacts: The double benefit of climate protection through both limiting and delaying global warming

09/27/2021 - Increasing global warming from currently one to two degrees Celsius by mid-century might lead to about 25 percent more people put at risk by tropical cyclones, a new study finds. Already today, hurricanes and typhoons are among the most destructive natural disasters worldwide and potentially threaten about 150 million people each year. Adding to climate change, population growth further drives tropical cyclone exposure, especially in coastal areas of East African countries and the United States. Considering the joint impact of climate change and population growth provides an untapped potential to protect a changing world population.

Today’s children to experience two to seven times more extremes than their grandparents

09/27/2021 - Today’s children will be hit much harder by climate extremes than today’s adults, researchers show in the leading journal Science. During their lifetime, a child born in 2021 will experience on average twice as many wildfires, between two and three times more droughts, almost three times more river floods and crop failures, and seven times more heatwaves compared to a person who’s for instance 60 years old today, the researchers find based on data from the Inter-sectoral Impact Model Intercomparison Project (ISIMIP). This is under a scenario of current greenhouse gas emission reduction pledges by governments which will be a topic at the upcoming world climate summit COP26 in Glasgow.

Limiting climate risks for finance: Central banks and science publish scenarios

06/07/2021 - To improve climate related risk management in the financial sector and facilitate a smooth transition toward a sustainable economy, over 90 central banks and financial market supervisors organized in the Network for Greening the Financial System joined forces with science. Together, researchers and financial experts now published an updated set of scenarios of an orderly transition, delayed transition, and climate policy failure. They show how early greenhouse gas emissions reductions can minimize both physical and financial risk. In contrast, delayed action or no action would inevitably drive up costs in the medium to long term. The analysis provides sectoral and regional detail to help financial institutions adapt their investment strategies.
