„Promoting evidence-based decision-making“: Qatar and PIK announce creation of climate change research institute

05.12.2012 - Qatar Foundation in partnership with the Potsdam Institute for Climate Impact Research (PIK) announced the creation of a pioneering climate change research institute. It will be the first of its kind “in a country whose wealth is founded on fossil fuels,” PIK’s director Hans Joachim Schellnhuber said. “Qatar declares to confront the climate challenge, and to do so by promoting research and evidence-based decision-making. This might be a turning point for a transition towards sustainability.” The science is clear, Schellnhuber said, that global greenhouse-gas emissions from fossil fuel consumption “have to decrease sharply by 2020 if we want to avoid dangerous climate change”.

Doha World Climate Summit: Schellnhuber gives talk to high-ranking representatives of states

12/06/2012 - “Don’t ask what global climate protection can do for your country; ask what your country can do for climate protection…” – it was by rephrasing former US president John F. Kennedy’s famous words that Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research (PIK), addressed the highest-ranking representatives of states in Doha. He had been asked to present the keynote at the gala dinner on Tuesday night that opened the high-level segment of the world climate summit COP18 – an unsual honour for a scientist.

4-degrees briefing for the World Bank: The risks of a future without climate policy

11/19/2012 - Humankind’s emissions of greenhouse gases are breaking new records every year. Hence we’re on a path towards 4-degree global warming probably as soon as by the end of this century. This would mean a world of risks beyond the experience of our civilization – including heat waves, especially in the tropics, a sea-level rise affecting hundreds of millions of people, and regional yield failures impacting global food security. These are some of the results of a report for the World Bank, conducted by the Potsdam Institute for Climate Impact Research (PIK) and Climate Analytics in Berlin. The poorest in the world are those that will be hit hardest, making development without climate policy almost impossible, the researchers conclude.

„Green Growth“– Fairytale or Strategy? Climate Lecture 2012 at TU Berlin

12/03/2012 - Economic growth does not only lead to rising turnovers and incomes but also increases greenhouse-gas emissions. Can “Green Growth” be a way out of this dilemma? Is it “a fairytale or a strategy”? Right now, issues like this are being debated at the international climate summit in Doha. Two scientists explored solution paths at the Climate Lecture at Technische Universität Berlin this Monday in front of 1000 guests – British growth critic Professor Tim Jackson and the chief economist of the Potsdam Institute for Climate Impact Research and Professor at TU Berlin, Ottmar Edenhofer.

„You cannot negotiate with nature“: Leading scientists on COP18 in Doha

11/26/2012 - Media worldwide asked leading scientists of the Potsdam Institute for Climate Impact Research (PIK) for comments and interviews on the world climate summit COP18 that started today in Doha, Qatar. Despite the widespread scepticism that the meeting of representatives of nearly 200 states will achieve much progress, PIK’s director Hans Joachim Schellnhuber stressed that much is at stake for the international community if global warming goes on unabated. “You cannot negotiate with nature,” Schellnhuber told the Chinese news agency Xinhua. “While we are quarreling, nature will just march on."

Projected sea-level rise may be underestimated

11/28/2012 - The rate of sea-level rise in the past decades is greater than projected by the latest assessments of the IPCC, while global temperature increases in good agreement with its best estimates. This is shown by a study now published in the journal Environmental Research Letters. Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research (PIK) and his colleagues compare climate projections to actual observations from 1990 up to 2011. That sea level is rising faster than expected could mean that the Intergovernmental Panel on Climate Change’s (IPCC) sea-level rise projections for the future may be biased low as well, their results suggest.

A warning system for the planet

11/16/2012 - Earth’s ecosystems provide benefits like food or drinking water that are of crucial importance for the well-being of humankind. But although accumulated assessments indicate increasing system failures threatening livelihoods and lives, so far no centralized system exists to monitor and report ecosystem status and changes. Aiming at a better understanding of the consequences of ecosystem service and biodiversity loss, a team of scientists, including Kirsten Thonicke and some of her colleagues from the Potsdam Institute for Climate Impact Research (PIK), propose “A Global System for Monitoring Ecosystem Service Change” in a paper recently published in the science magazine “BioScience”.

Potsdam hosts first World Climate Impacts Conference

11/15/2012 - The first World Climate Impacts Conference, IMPACTS WORLD 2013, will be held next year in Potsdam, Germany. "Our climate future will be largely determined by the choices we make in the next couple of decades – everything between 2°C and 10°C global warming by 2300 is possible,” says Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research which is organising the event together with the International Institute for Applied Systems Analysis (IIASA). “Impacts science has come of age now and can finally draw the dramatic sectoral and regional pictures associated with specific increases in the Earth’s mean surface temperature”.

Rise and fall of the Maya in response to climate change

11/09/2012 - The role of climate change in the development and disintegration of classic Maya civilization, ranging from AD 300 to 1000, has been controversial for decades because of the absence of well-dated climate and archaeological sequences. In an article now published in Science, an international and interdisciplinary team of scientists including Norbert Marwan from the Potsdam Institute for Climate Impact Research (PIK) presents a precisely dated, high resolution regional climate record for the past 2000 years that for the first time shows how the Maya political systems developed and disintegrated in response to climate change.

Most coral reefs are at risk unless climate change is drastically limited

09/16/2012 - Coral reefs face severe challenges even if global warming is restricted to the 2 degrees Celsius commonly perceived as safe for many natural and man-made systems. Warmer sea surface temperatures are likely to trigger more frequent and more intense mass coral bleaching events. Only under a scenario with strong action on mitigating greenhouse-gas emissions and the assumption that corals can adapt at extremely rapid rates, could two thirds of them be safe, shows a study now published in Nature Climate Change. Otherwise all coral reefs are expected to be subject to severe degradation.

“Orchestra of Change”: Schellnhuber joins board of trustees of NaturTon Foundation

10/12/2012 - The director of the Potsdam Institute for Climate Impact Research, Hans Joachim Schellnhuber, becomes a member of the board of trustees of NaturTon Foundation. The charitable foundation was founded in 2009 by musicians of the Staatskapelle Berlin. Their initiative „Orchestra of Change“ combines cultural and environmental commitments. „Science can reach the minds of men, but music reaches the heart,“ PIK-director Schellnhuber says. „The writing of thousands of scientific papers cannot stimulate enough momentum, therefore it is good for science and music to work together.“

Restricting nuclear power has little effect on the cost of climate policies

10/01/2012 - Incremental costs due to policy options restricting the use of nuclear power do not significantly increase the cost of even stringent greenhouse-gas emissions reductions. By applying a global energy-economy computer simulation that fully captures the competition between alternative power supply technologies, a team of scientists from the Potsdam Institute for Climate Impact Research and the University of Dayton, Ohio, analyzed trade-offs between nuclear and climate policies. Strong greenhouse-gas emissions reduction to mitigate global warming shows to have much larger impact on economics than nuclear policy, according to the study published this week in the Proceedings of the National Academy of Sciences.

“It pays to be a forerunner”: studies explore second-best scenarios of climate policy

09/27/2012 - Industrialized countries can profit from taking early action for climate change mitigation even if the rest of the world delays greenhouse gas emission cuts. With the 2 degrees target of limiting global warming, it pays in the long term to incentivize investments into clean energy instead of fossil fuels by adopting ambitious emission reductions. This is one of the key findings of scientists exploring the economics of decarbonization in an imperfect world, in a set of seven papers now published in a special issue of Climatic Change. They will feed into the 5th assessment report of the Intergovernmental Panel on Climate Change.

Constraining world trade is unlikely to help the climate

09/23/2012 - From rubber dinghies to television sets: the emissions of greenhouse gases in countries like China are to a significant extent caused by the production of goods that are exported to Germany or the United States. But this doesn´t necessarily mean that Western countries have relocated their emission-intensive industries and hence escape regulation for climate protection. This is shown in a study appearing in Nature Climate Change this week. Instead, researchers were able to pin down a number of factors explaining the pronounced imbalances between emission importers and exporters, the US current account deficit being one of them. Their conclusion: interventions in world trade, like CO2 tariffs, would probably have only a small impact on global emissions.

„Record sea-ice melt a warning sign“: top German Arctic researchers

09/19/2012 - This summer’s record low of Arctic sea-ice is a warning sign, some of Germany’s leading ice researchers stated in a joint press conference in Hamburg today. Never before since the beginning of satellite observations – and very probably even since 1500 years or more – the sea-ice cover shrunk to such small area. “The record melt measured some weeks ago has thus been exceeded significantly again, leaving the 2012 record 23 percent below the previous record just five years before,” said Anders Levermann of the Potsdam Institute for Climate Impact Research.

Between intense rain events und parched earth: Climate change impacts in Germany

08/06/2012 - Climate change has implications not only in far-away regions of the world but in Germany, too. And these implications are relevant not tomorrow but already today. By the middle of this century these consequences will be amplified. What climate change impacts - which can be very different from region to region - could actually look like, is the subject of the conference “Climate Impacts in Germany”, organized by the Potsdam Institute for Climate Impact Research (PIK), the German federal state Brandenburg and the Humboldt University Berlin, taking place on September 24th 2012 in Berlin. For the first time, climate change impacts on a time horizon up to the year 2100 are addressed across all sectors for the different regions in Germany.
