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).

PIK & MCC STATEMENT: “German Government has not delivered”

20/09/2019 - The German government decided today to initiate carbon pricing in the transport and heating sectors. It is to start at 10 euros and gradually rise to 35 euros in 2025. In 2026, the pricing scheme will be converted into a national emissions trading system with a minimum price of 35 euros and a maximum price of 60 euros; how things will continue thereafter shall be determined in 2025. Ottmar Edenhofer, Director of the Mercator Research Institute on Global Commons and Climate Change (MCC) and the Potsdam Institute for Climate Impact Research (PIK), comments:

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.

Six Transformations to achieve the Sustainable Development Goals

26/08/2019 - The Sustainable Development Goals (SDGs) and the Paris Agreement on Climate Change call for deep transformations that require complementary actions by governments, civil society, science, and business. While significant progress is being made on some goals, no country is currently on track towards achieving all SDGs. PIK Director Johan Rockström contributed to a paper published now in Nature Sustainability, outlining six major transformations that will be required to achieve these ambitious goals. Led by the United Nations Sustainable Development Network (UNSDSN), the research will be an input to the upcoming United Nations General Assembly Climate Summit on September 23 and 24 in New York City. Rockström will be a speaker at a number of events.

Indian monsoon forecast: early warning for risk of flooding in October

The Indian Summer Monsoon is likely to withdraw from the Central part of India between 14th and 24th October 2019. The unique forecast, made for 70 days in advance, is the only available long-term forecast in India. Elena Surovyatkina, climate scientist at the Potsdam Institute for Climate Impact Research, leads the forecasts that showed to be successful already three years in a row. The monsoon withdrawal date is of crucial importance for billion of people in India. In a warming world, severe storms and floods during monsoon retreat are becoming more frequent. Such a long-term forecast could help Government to do strategic planning, consolidate resources, and strengthen capacity to respond effectively to disasters.

Looking beyond the farm gate: New IPCC Special Report on Land Use and Climate Change

08/08/2019 – Almost three quarters of habitable land on earth are under human use – resulting in substantial impacts on our climate, a new report of the Intergovernmental Panel on Climate Change (IPCC) shows. Today, almost a quarter of human-made greenhouse gas emissions arise from agriculture, forestry and other land use. The latest IPCC Special Report investigates the current situation, possible future scenarios and potential solutions on how we can use land to feed ourselves, fuel economic growth and limit climate change risks. Two Potsdam scientists figure as lead authors of the chapter on food security and on the relations between land and climate.

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.

Sea level rise: West Antarctic ice collapse may be prevented by snowing ocean water onto it

18/07/2019 - The ice sheet covering West Antarctica is at risk of sliding off into the ocean. While further ice-sheet destabilisation in other parts of the continent may be limited by a reduction of greenhouse gas emissions, the slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilised. A collapse might take hundreds of years but will raise sea levels worldwide by more than three meters. A team of researchers from the Potsdam Institute for Climate Impact Research (PIK) is now scrutinising a daring way of stabilising the ice sheet: Generating trillions of tons of additional snowfall by pumping ocean water onto the glaciers and distributing it with snow canons. This would mean unprecedented engineering efforts and a substantial environmental hazard in one of the world’s last pristine regions – to prevent long-term sea level rise for some of the world’s most densely populated areas along coastlines from the US to China.

“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.

Breaking the rules: Monsoon and climate change

26.06.2019 - With global warming the Monsoon is changing, breaking well-established “rules” of the phenomenon, becoming more and more erratic and unpredictable. Close to half of the global population depends on monsoon rainfall. For the fourth year in a row, Elena Surovyatkina from the Potsdam Institute for Climate Impact Research (PIK) successfully predicted the onset of the Indian Summer Monsoon in the central part of India more than a month in advance with a new forecast method. This method accounts for climate change effects and hence makes forecasting possible.

Initiated instability in West Antarctica might be the fastest on the continent

13/06/2019 - All around the Antarctic coastline there are ice sheet instabilities waiting to be triggered. If this happens ice flows inexorably into the ocean and raises sea levels worldwide. The one region where instability likely has already been initiated by a warming of the ocean is probably the region which collapses faster than any other, find scientists from the Potsdam Institute for Climate Impact Research (PIK). Even though the rapid ice loss takes decades to unfold and centuries to complete, the speed of ice loss from Antarctica is already a major driver of global sea level rise. It will affect hundreds of millions of people living near the world’s coastlines, from Miami to Shanghai.

Climate protection and peace are two sides of the same coin: Berlin Climate and Security Conference

04/06/2019 –Climate change knows no borders, and climate crises can affect security, ranging from food security and displacement to an increasing number of natural disasters. Indeed, a destabilised Earth system can make peace harder to achieve and sustain, and may even be a contributing factor to new violent conflicts. This makes our climate a foreign policy issue. In cooperation with the Federal Foreign Office and the think tank adelphi, the Potsdam Institute for Climate Impact Research has initiated the Berlin Climate and Security Conference to provide a forum for this rising issue. The summit will gather support for the “Berlin Call for Action”, directed at every foreign policy institution to step up efforts to address one of the greatest global security and foreign policy challenges of the 21st century: Climate change.
