SPECIAL: Climate plan for Germany and Europe: Economists propose CO2 price reform

Arctic Sea IceA few days ago the UN Environment Agency advocated an international green tax reform - now economists have presented a new concept for a CO2 price reform in Germany and Europe right before the start of the climate summit in Katowice, Poland. SPIEGEL magazine was reporting on this issue in advance this weekend. Christoph Schmidt, Chair of the German Council of Economic Experts from RWI Essen, Leibniz Institute for Economic Research, and Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), have jointly drafted the cornerstones for a market-based way out of coal. Climate-damaging CO2-emissions would need to become more expensive, while at the same time the electricity tax could be lowered. A socially just and efficient transition to a sustainable economy is possible, according to the professors, who both belong to the Leibniz Association. If, on the other hand, greenhouse gas emissions were not reduced, there would be the risk of economic climate damage of unprecedented proportions. Read more...

German industry and climate experts: G20 should push CO2 pricing

German industry and climate experts: G20 should push CO2 pricing

09/02/2016 - An unusual alliance of business, science and an environmental organization is urging the major economies meeting as G20 this weekend in Hanghzou, China, to push CO2 pricing. The Federation of German Industries (BDI), Germanwatch and the Mercator Research Institute on Global Commons and Climate Change (MCC) led by Ottmar Edenhofer - chief economist of the Potsdam Institute for Climate Impact Research - published a joint proposal in the german weekly ‘Die Zeit’. Pricing greenhouse-gas emissions from fossil fuels is key to achieve the climate stabilization goals set forth in the Paris Agreement, the authors argue. It should both set incentives for CO2 reductions and create more predictability for planning, the authors argue. In the same time, the instrument could raise much-needed revenues for infrastructure investments. The initiative comes ahead of the announcement of the agenda of Germany’s G20 Presidency to commence in December.

Amazon forests: Biodiversity can help mitigate climate risks

Amazon forests: Biodiversity can help mitigate climate risks

29/08/2016 - A forest with greater diversity of plants can better adjust to climatic stress. Now for the first time, a team of scientists can show this in computer simulations of the Amazon region by accounting for its amazing diversity of trees. Biodiversity can hence be an effective means to mitigate climate risks and should not only be seen in the context of nature conservation.

Dealing with Climate Change Impacts – the Potsdam Summer School starts with young talents from all over the world

Dealing with Climate Change Impacts – the Potsdam Summer School starts with young talents from all over the world

From global sea level rise to extreme events like floods or droughts – even with ambitious climate mitigation, some impacts of climate change will be felt within this century. How to avoid the unmanageable and manage the unavoidable will be the focus of the Potsdam Summer School from September 5-14, bringing together more than 40 early-career scientists and young professionals from all around the globe.

Climate change: Trade liberalization could buffer economic losses in agriculture

Climate change: Trade liberalization could buffer economic losses in agriculture

08/25/2016 - Global warming could create substantial economic damage in agriculture, a new study conducted by a team of scientists of the Potsdam Institute for Climate Impact Research (PIK) finds. Around the globe, climate change threatens agricultural productivity, forcing up food prices. While financial gains and losses differ between consumers and producers across the regions, bottom line is that consumers in general will likely have to pay more for the same basket of food. As the additional expenditure for consumers outweighs producers’ gains, increasing net economic losses will occur in the agriculture and food sector towards the end of the century. However, economic losses could be limited to 0.3 percent of global GDP – depending on agricultural trade policies.

Can we economically outgrow climate change damages? Not for hurricanes we can't

Can we economically outgrow climate change damages? Not for hurricanes we can't

08/16/2016 - When hurricanes like Katrina in 2005 or Sandy in 2012 impact on highly populated regions they bring about tremendous damages. More than 50 percent of all weather-related economic losses on the globe are caused by damages due to tropical cyclones. Researchers from the Potsdam Institute for Climate Impact Research (PIK) now analyzed the magnitude of future hurricane losses in relation to economic growth. Showcasing the United States they found that financial losses per hurricane could triple by the end of the century in unmitigated climate change, while annual losses could on average rise by a factor of eight. Most importantly and contrary to prevalent opinion, they conclude that economic growth will not be able to counterbalance the increase in damage.

New interactive climate spirals online

New interactive climate spirals online

07/27/2016 - Global-mean temperatures are breaking one record after the other since instrumental observations began. Driven by burning of fossil fuels and deforestation, carbon dioxide concentrations have also soared to unprecedented levels. In fact, today's CO2 concentrations are higher than they have ever been over the last 800 thousand years. Scientists from the Potsdam Institute for Climate Impact Research (PIK) and the University of Melbourne now put all these elements together to provide a set of new interactive Climate Spiral visualizations.
