02/24/2014 - There are networks within the climate system of the earth: Changes at one point can trigger changes at another, far away point – so an El Niño-event in South America can interfere with the Asian monsoon. Up to now, these correlations could only be determined statistically by comparing observation data and time series. A study now for the first time reveals the physical mechanisms behind the statistics. According to an article published by scientists of the Potsdam Institute for Climate Impact Research in the journal Scientific Reports, a new open access journal of the renowned Nature group, flows are of prime interest here.
02/18/2014 - Glaciers are melting in the Andes and the rain forest of the Amazon is threatened – Colombia knows the risks of global warming. The Minister of the Environment Luz Helena Sarmiento Villamizar together with her vice minister and other high-ranking representatives of the South American country came to the Potsdam Institute for Climate Impact Research (PIK) for discussions about the research on climate impacts and countermeasures. The end of the internal armed conflicts of many years leads to increased forest clearing – the pressure on the ecosystems is thus increasing from all sides, according to the Minister. Therefore, she is urgently seeking scientific support.
02/17/2014 - Renowned scientists met at the annual conference of the Climate Service Center last week on Potsdam´s Telegraph Hill. Under the motto “Society under climate change: Which adaptation is necessary, possible, and sustainable?” the issue of adaptation was in the focus for two days – since even if global warming was limited to two degrees Celsius, the impacts would already be significant. The Climate Service Center (CSC) of the Helmholtz Center Geesthacht, whose offices are located in Hamburg, is funded by the Federal Government.
02/11/2014 - The most crucial instrument of European climate policy, the Emissions Trading System (ETS), is currently questioned to deliver the desired results as the sum to pay per ton of carbon is dwindling. To move beyond a narrow discussion of the adequate allowance price level, the association of European national academies of applied sciences Euro-CASE along with the Mercator Research Institute on Global Commons and Climate Change (MCC) is convening a high-level workshop in Brussels this week. It aims at exploring options for a reform, and to do so by embedding the discussion about the ETS in the context of its interaction with national policies as well as public finance.
06/02/2014 - Extreme weather events like super-typhoon Haiyan and hurricane Sandy can have major negative impacts on the world economy. So far, however, the effects on global production and consumption webs are missing from most assessments. This is a serious deficit, argues Anders Levermann from the Potsdam Institute for Climate Impact Research: “World markets as well as local economies are highly interlinked and rely on global supply chains – adaptation therefore requires a global perspective, not just a local one.” In a Nature Commentary he proposes a community effort to collect economic data on the new website zeean.net. The aim is to better understand economic flows and to thereby induce a transformation of our supply chains into a stable, climate-smart network that renders our societies less vulnerable to future climate impacts.
02/04/2014 - Without increased coastal protection, between one and ten out of 200 people per year could be affected by flooding by the end ouf our century. In such a scenario of unmitigated climate change, the damages induced by sea-level rise without adaptive measure could be expected to be between 1.2 and 9.3 percent of economical activity. These are some results of a yet unprecedentedly broad analysis now published in the Proceedings of the National Academy of Sciences. Building dikes would cost substantial amounts of money – yet much less than the damages by flooding without protection, according to the analysis.
01/31/2014 - Ottmar Edenhofer discusses “Climate Change as a Challenge for International Politics” at the 50th Munich Security Conference. From crop failure due to climate change to scarcity of resources or migration flows – the potential risks of climate change for stability, development and security are in the focus of the event with renowned experts and decision makers.
