Climate tipping points – too risky to bet against

28/11/2019 - From the Greenland and West-Antarctic ice sheets to coral reefs or the Amazon rainforest – a number of critical elements in the Earth system could be more likely to tip than was previously thought, a group of leading scientists warns in in the highly renowned journal Nature. Evidence is mounting that these events are also more interconnected, which could eventually lead to domino effects. A possible tipping cascade of irreversible changes might put the livelihoods of people around the world at risk and marks a state of planetary emergency, the authors argue in their comment.

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.

Lancet Countdown: Forschungsbericht zu Klimawandel und Gesundheit

14.11.2019 - Bis zum Ende dieses Jahrhunderts sind jährlich bis zu fünf zusätzliche Hitzewellen in Norddeutschland und bis zu 30 in Süddeutschland zu erwarten, wenn wir mit dem Ausstoß von Treibhausgasen so weitermachen wie bisher. Damit einhergehender Hitzestress und hohe bodennahe Ozonkonzentrationen können schwerwiegende Folgen für die menschliche Gesundheit haben. Dazu zählen unter anderem Hitzschlag, Herzinfarkt und akutes Nierenversagen aufgrund von Flüssigkeitsmangel. Am stärksten gefährdet sind ältere Menschen, Säuglinge, Patienten mit chronischen Erkrankungen sowie Personen, die schwere körperliche Arbeit im Freien verrichten, etwa Bauarbeiter.

From Berlin to New York: United in Science

23/09/2019 - Millions of people all around the globe crowded the streets last Friday, demanding rapid action from policy makers to counter climate risks. The Fridays for Future movement calls upon humanity to "unite behind the science". That very same day, the German government adopted a climate policy package relying on carbon pricing expertise provided by PIK Director Ottmar Edenhofer and colleagues. Yet, the policy package is too weak to meet the climate targets, the expert says. Currently, heads of state are meeting at the UN climate summit – German Chancellor Angela Merkel is one of them. Again, science provides the facts needed for sound decisions. Among other input, PIK Director Johan Rockström presented an "Exponential Roadmap" to sustainability in New York with colleagues. Climate stabilization is both necessary and possible, the science shows.

PIK and MCC deliver detailed assessment of German climate package

14/10/2019 - The climate protection programme adopted by the Federal Government last week, which is intended to limit greenhouse gas emissions especially in the transport and heating sectors, is unlikely to be sufficient to achieve the 2030 climate targets. Policymakers need to make four particular adjustments: first, they need to raise the level of ambition for the carbon price; second, they need to improve social balance; third, they need to develop further its integration with the EU level; and fourth, they need to introduce an effective monitoring process. This is the core message of a detailed assessment of the climate package, presented by the Berlin climate research institute MCC (Mercator Research Institute on Global Commons and Climate Change) and the Potsdam Institute for Climate Impact Research (PIK).

Earth League scientists back global climate protests

18/09/2019 - Humanity is tipping the scales of the world, eminent Earth League scientists say in a joint statement. They throw their weight into the balance to support global climate action culminating in this Friday's demonstrations and the UN climate summit next week. The future of life-support systems on Earth is determined by a dual tipping - for better or worse. Either a social tipping towards sustainability happens quickly, or all too soon a tipping of critical parts in the Earth System may threaten the stability of life on our planet. The scientists call upon everyone to demand that political and economic decision makers ensure we do not leave our children to an insecure future.

From avocados to apples: Producing food closer to cities could help reduce climate emissions

29.08.2019 - Millions of tons of groceries from agriculture are transported to our cities all around the globe every day to feed its dwellers. Produced anywhere in the world and transported as cargo on roads, rail or water from the farm gate into cities, this food transport is linked to a huge amount of CO2 emissions. Exploring options to reduce this “food-print”, a team of city researchers from the Potsdam Institute for Climate Impact Research (PIK) now provides the first global analysis of the potential of local food production to feed hungry cities in present and future. As it turns out, a large number of urban residents in many parts of the world could be nourished by local agriculture. However, climate change might take that option off the table, if greenhouse gas emissions are not rapidly reduced.

What Counts for Our Climate: Carbon Budgets Untangled

18/07/2019 - The more CO2 we emit from burning coal and oil and gas, the more we heat our climate – this sounds simple, and it is. Different analyses have come up with different estimates of how much CO2 humankind can still emit if we want to hold global warming to the internationally agreed 1.5 and well below 2 degrees Celsius limits, but a lack of clarity of the reasons causing these variations has created unnecessary confusion, a new study shows. It identifies the relevant factors that affect estimates of these remaining carbon budgets and thereby untangles the differences to make estimates more easily comparable, which will help decision-makers in using them. From a climate policy perspective, the bottom line remains the same. Even if the remaining carbon budget for limiting warming to 1.5°C would increase by a half, we would have only 10 years more time before emissions have to be brought down to net zero.

“New Market Design is needed”: lessons to learn from renewable energy regulation in California and Germany

09.07.2019 - Important lessons can be learned from the two global frontrunners in the energy transition, Germany and California, a new report shows. Being the 4th biggest and 5th biggest economies worldwide, both jurisdictions draw more than 30 percent of their electricity from wind and solar and biomass, both have ambitious renewables targets of 80 and 100 percent by mid-century. An international team of scientists from Germany and the US now analyzed Californian and German policy pathways to draw conclusions for the way ahead. They find that market and renewable policy design adjustments in both jurisdictions to integrate the first 30 percent were small compared to the adjustments needed to integrate the second 30 percent. Importantly, strengthening CO2-pricing and policies to foster electrification must be an integral part of this.

Strengthening climate protection "bottom up": Municipal workshop at PIK

27.06.2019 - Mayors and other representatives of municipalities and counties in Germany meet this week in Potsdam to discuss how climate protection can be strengthened "bottom up". Organised by the Potsdam Institute for Climate Impact Research (PIK), the two-day "KliB-up Municipal Workshop" will focus on a climate friendly everyday lifes and the involvement of citizens in active municipal climate protection. Many municipalities and rural districts have been active in this field for years and have set themselves ambitious climate targets, such as the so-called master plan municipalities in Germany. These targets can hardly be achieved without the commitment of private households. How a climate friendly everyday life could look like in practice, more than 100 households in Berlin recently already tested that in the context of the PIK living lab "Klimaneutral leben in Berlin" (KliB). As a result, the participating households were about 33 percent below the German average at the end of the one-year project.

German coal phase-out could be in vain without CO2-pricing

04/06/2019 - It cannot be taken for granted that Germany’s plan to phase out coal by 2038 will actually decrease CO2 emissions on the European level. On the contrary, the phase-out could even increase emissions due to a complicated new mechanism in the European Emissions Trading Scheme, a team of researchers shows in a new analysis. To make sure the coal phase-out really helps stabilise the climate, it must be combined with a minimum price for CO2 or the cancellation of existing emission certificates.
