Stock-take 2018: Rapid emissions reductions would keep CO2 removal and costs in check

Stock-take 2018: Rapid emissions reductions would keep CO2 removal and costs in check

03/29/2018 - Rapid greenhouse-gas emissions reductions are needed if governments want to keep in check both the costs of the transition towards climate stabilization and the amount of removing already emitted CO2 from the atmosphere. To this end, emissions in 2030 would need to be at least 20 percent below what countries have pledged under the Paris climate agreement, a new study finds – an insight that is directly relevant for the global stock-take scheduled for the UN climate summit in Poland later this year. Removing CO2 from the atmosphere through technical methods including carbon capture and underground storage (CCS) or increased use of plants to suck up CO2 comes with a number of risks and uncertainties, and hence the interest of limiting them.

Enhanced weathering of rocks can help to suck CO2 out of the air – a little

Enhanced weathering of rocks can help to suck CO2 out of the air – a little

03/06/2018 - Weathering of huge amounts of tiny rocks could be a means to reduce the greenhouse gases in the atmosphere. While this is normally a slow natural process during which minerals chemically bind CO2, technological upscaling could make this relevant for so-called negative emissions to help limit climate risks. Yet, the CO2 reduction potential is limited and would require strong CO2 pricing to become economically feasible, according to the first comprehensive assessment of costs and possibilities now published in the journal Environmental Research Letters.

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.

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

Coal phase-out: Announcing CO2-pricing triggers divestment

Coal phase-out: Announcing CO2-pricing triggers divestment

01/29/2018 - Putting the Paris climate agreement into practice will trigger opposed reactions by investors on the one hand and fossil fuel owners on the other hand. It has been feared that the anticipation of strong CO2 reduction policies might – a ‘green paradox’ – drive up these emissions: before the regulations kick in, fossil fuel owners might accelerate their resource extraction to maximize profits. Yet at the same time, investors might stop putting their money into coal power plants as they can expect their assets to become stranded. Now for the first time a study investigates both effects that to date have been discussed only separately. On balance, divestment beats the green paradox if substantial carbon pricing is credibly announced, a team of energy economists finds. Consequently, overall CO2 emissions would be effectively reduced.

Biomass plantations not compatible with planetary boundaries

Biomass plantations not compatible with planetary boundaries

01/22/2018 - Planting trees or grasses on a grand scale in plantations to extract CO2 from the atmosphere - this could make a long-term contribution to climate protection, but it would push the planet beyond ecological limits in other dimensions. A new study by the Potsdam Institute for Climate Impact Research (PIK) in the journal Nature Climate Change now for the first time establishes a connection between ambitious international climate objectives and the more comprehensive concept of planetary boundaries. If biomass plantations in which plants bind carbon dioxide during growth are massively expanded, this would entail enormous risks for areas that are already stressed, such as biodiversity, biogeochemical flows, water resources and land use. According to the study, biomass as a means to capture and store CO2 can therefore only make a limited contribution. In order to stabilize the climate, a rapid reduction of greenhouse gas emissions from the combustion of coal, oil and gas is crucial.

Adaptation now: River flood risks increase around the globe under future warming

Adaptation now: River flood risks increase around the globe under future warming

11/01/2018 - Rainfall changes caused by global warming will increase river flood risks across the globe. Already today, fluvial floods are among the most common and devastating natural disasters. Scientists have now calculated the required increase in flood protection until the 2040s worldwide, breaking it down to single regions and cities. They find that the need for adaptation is greatest in the US, parts of India and Africa, Indonesia, and in Central Europe including Germany. Inaction would expose many millions of people to severe flooding.

Tiny ice losses at Antarctica’s fringes can accelerate ice loss far away

Tiny ice losses at Antarctica’s fringes can accelerate ice loss far away

12/12/2017 - A thinning of small areas of floating ice at Antarctica’s coast can accelerate the movement of ice grounded on rocks hundreds of kilometers away, a new study shows. It is known that the ice shelves surrounding the continent regulate the ice flow from the land into the ocean. So far it was assumed that the ice flow is most vulnerable to melting at the base near the grounding line where the ice flows from land into the sea and becomes afloat. Now scientists found that also melting near the fringes and in the midst of the ice shelves can have direct effects reaching very far inland. This could increase ice loss and hence sea-level rise.

Transformation to wind and solar could be achieved with low indirect greenhouse gas emissions

Transformation to wind and solar could be achieved with low indirect greenhouse gas emissions

12/08/2017 - Different low carbon technologies from wind or solar energy to fossil carbon capture and sequestration (CCS) differ greatly when it comes to indirect greenhouse gas emissions in their life cycle. This is the result of a comprehensive new study conducted by an international team of scientists that is now published in the journal Nature Energy. Unlike what some critics argue, the researchers not only found that wind and solar energy belong to the more favorable when it comes to life-cycle emissions. They also show that a full decarbonization of the global power sector by scaling up these technologies would induce only modest indirect greenhouse gas emissions – and hence not impede the transformation towards a climate-friendly power system.

“We need you”: UN climate chief to Potsdam climate scientists

“We need you”: UN climate chief to Potsdam climate scientists

10/13/2017 - Hundreds of millions of people will be affected by climate change impacts and their implications for health or migration already within the next few decades, sectors that so far often get overlooked in this context. This is one of the insights of the Impacts World Conference organised by the Potsdam Institute for Climate Impact Research (PIK) in Germany this week. About 500 scientists from 67 countries were gathering at the conference with the title “Counting the true costs of climate change” to push climate impact research to the next level by better integrating socio-economic factors. At the same time, the institute celebrated its 25th anniversary hosting this meeting of the global impacts research community, in the spirit of its mission followed for a quarter century: further advancing scientific progress and communicating insights to stakeholders.

Ending tax breaks after the diesel scandal

Ending tax breaks after the diesel scandal

09/19/2017 - In response to the diesel scandal, the diesel tax advantage should be completely abandoned within the European Union (EU). In Germany, for example, diesel would then be about 20 cents per liter more expensive at the pump. In return, however, this measure would allow Germany but also France to reduce the emissions of CO2 and nitrogen oxides (NOx) by about 10 percent over five years. This is because diesel drivers in particular are much more sensitive to fuel price changes than previously assumed: a price hike of 20 cents per liter would lower their overall consumption by an estimated 14 percent.
