The Climate Crisis and Churches' Options for Action: Ecumenical Learning Journey to PIK
05/03/2020 - 32 representatives from several churches took on a leaning journey about climate change and its consequences in Berlin and Potsdam. At the Potsdam Institute for Climate Impact Research, Wolfgang Lucht shared some insights on Earth system research. The participants' conclusion: The church can play a major role in bridging the gap between knowledge and action and contribute to a different lifestyle through ecological spirituality.

Buildings can become a global CO2 sink if made out of wood instead of cement and steel
A material revolution replacing cement and steel in urban construction by wood can have double benefits for climate stabilization, a new study shows. First, it can avoid greenhouse gas emissions from cement and steel production. Second, it can turn buildings into a carbon sink as they store the CO2 taken up from the air by trees that are harvested and used as engineered timber. However while the required amount of timber harvest is available in theory, such an upscaling would clearly need most careful, sustainable forest management and governance, the international team of authors stresses.

Tipping mechanisms could spark profound societal change towards climate stabilization: new study
21/01/2020 - Limiting global warming to well below 2°C requires a decarbonized world by 2050 at the latest and a corresponding global transformation of the energy and land use systems of societies across the world. To achieve this goal of net-zero carbon by 2050 emissions need to be cut by half every decade from now on. An interdisciplinary team of researchers now explored tipping mechanisms that have the potential to spark rapid yet constructive societal changes towards climate stabilization and overall sustainability. These tipping elements and mechanisms could bring about a transition that is fast enough for meeting the targets of the Paris climate agreement. Published in the Proceedings of the National Academy of Sciences (PNAS) the scientists identify six socio-economic tipping elements and related interventions that could bring such a transition to a deep and rapid global decarbonization on its way.

Australian bush fires: "What is happening in the southeast of Australia right now is breaking all records"
10/01/2020 - Australia is burning. In a statement, Kirsten Thonicke, expert for fire ecology and forests at the Potsdam Institute for Climate Impact Research (PIK), explains the causes and how the devastating fires are related to man-made climate change.

Germany likely to ramp up CO2 price path
16/12/2019 - Germany is likely to introduce a more ambitious carbon price path than previously envisioned by the Federal government. The mediation committee of the two legislative bodies agreed on a starting price of 25 Euro per ton CO2 in 2021, gradually rising to 55 Euros in 2025. Previously, the German government's plan was to start with 10 Euro, rising to 35 Euro. The national pricing scheme is supposed to complement the European Union's Emissions Trading System. The Green Deal plans just announced by Ursula von der Leyen, President of the European Commission, might also comprise more substantial carbon pricing. On this issue Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and of the Mercator Research Institute on Global Commons and Climate Change (MCC):

Edenhofer: "The European Green Deal is a bold plan"
12/12/2019 - The President of the EU Commision, Ursula von der Leyen, today presented the European Green Deal in Brussels. On Thursday, the European Council will debate it. Furthermore, it will be presented at the world climate summit COP25 in Madrid. On this issue, Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) said in a statement: "The European Green Deal is a bold plan that must now be followed by concrete action."

Schlacke and Edenhofer chair steering committee of “Climate Protection Science Platform” of the Federal Government
22.11.2019 - The Federal Government assigns scientific advisors for the Climate Action Plan 2050. A steering committee consisting of representatives of outstanding research institutions control the “Climate Protection Science Platform". These representatives elected Sabine Schlacke, a lawyer from the University of Münster, and economist Ottmar Edenhofer of the Potsdam Institute for Climate Impact Research and of the Mercator Research Institute on Global Commons and Climate Change as its chairs. As the voice of science, the platform will advise the government on the implementation and further development of the German climate strategy and contribute to the achievement of climate goals. The important aspect here is that it is independent and can act on its own initiative.

Decarbonizing the power sector: renewable energy offers most benefits for health and environment
19/11/2019 - Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts - such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international team of researchers led by the Potsdam Institute for Climate Impact Research (PIK) has now quantified the actual benefits and downsides of three main roads to decarbonisation. They show that relying mainly on wind and solar would bring most co-benefits for the health of people and planet. Switching to carbon capture and storage in combination with fossil and biomass resources, in turn, is likely to convey significant environmental costs by devouring large areas at the cost of biodiversity, and by releasing pollutants to the environment.
