"Economic optimization risks tipping of important Earth system elements"
Business Mirror (Philippines) - Scientists from the Potsdam Institute for Climate Impact Research (PIK) now used mathematical methods for the comparison of different economic and governance concepts. It turned out that the concept of profit maximization is not sufficient to avoid the tipping of critical elements in the Earth system that could dramatically change our livelihoods. And which of the other examined concepts (sustainability or the safe operating space approach, relying on the Planetary Boundaries concept) is most suitable, depends on the specific circumstances: "It turns out that there is no master concept for countering environmental challenges", says PIK-scientist Jürgen Kurths who contributed to the study.

"Lab-grown livestock feed may ease climatic effects of feed production"
UPI News Agency (USA) - Today's conventional agricultural feed cultivation has severe impacts on the environment and climate. A new study with involvement of the Potsdam Institute for Climate Impact Research (PIK) now evaluated the potential economic and environmental effects of an increasing replacement of the conventional feed by industrial microbes. "Cultivating feed protein in labs instead of using croplands might be able to mitigate some environmental and climatic impacts of feed production", says PIK-scientist Benjamin Bodirsky who contributed to the study.

"West Antarctic Ice Sheet unlikely to reverse retreat"
Iran Daily (Iran) - After the last ice age about 10.000 years ago, the Antarctic ice was melting due to rising temperatures. The retreat was then surprisingly reversed by processes which themselves were also caused by the melting. But these reversal processes are slow: "Given the speed of current climate change from burning fossil fuels, the mechanism we detected unfortunately does not work fast enough to save today's ice sheets from melting and causing seas to rise" says Torsten Albrecht from the Potsdam Institute for Climate Impact Research (PIK) who was one of the authors of the study.

"Scientists trace ice sheets in history of West, East Antarctica"
Xinhua News Ageny (China) - After the end of the last ice-age, the shrinking of the Antarctic ice itself stopped the shrinking: without the weight of the melted ice, the Earth crust lifted - and thus triggered the re-advance of the ice sheet. "[The ice] retreated inland by more than 1.000 kilometers in a period of 1.000 years in this region. [...] Instead of total collapse, the ice-sheet grew again by up to 400 kilometers. This is an amazing self-induced stabilization", says the concerning study's co-author Torsten Albrecht from the Potsdam Institute for Climate Impact Research (PIK). But this slow reversal mechanism will not stop sea-level rise today. Source: Xinhua (China), 14.06.2018.

"Global warming: trouble with water resources in Central Asia will increase"
Kabar News Agency (Kyrgyzstan) - At the Potsdam Institute for Climate Impact Research (PIK), more than 300 scientists investigate crucial topics of global environmental change, climate change impacts and sustainable development on a global and on a regional scale. Among the analyzed regions is Central Asia, where questions of water are particularly complex. "Water resources are the foundation for political, social and economic stability", says PIK-scientist Anastasia Lobanova in an interview with the major Kyrgyz news agency Kabar.

"Trump's economic isolationism is climate-blind"
The Hill (USA) - "Trump does not believe in climate change, but that won't make it go away, and it does not only have consequences for the much-ridiculed polar bears and coral reefs. It spells trouble for national economies across the globe and all of our wallets as well", writes PIK-scientist Anders Levermann in a guest commentary. "The destabilization of the climate that we are causing by our carbon emissions needs to be stopped: The burning of coal, oil and gas has to be phased out. We need climate realism instead of national chauvinism." Source: The Hill (USA), 29.05.2018.

"Want to Escape the Coming Floods? Balance Global Trade"
Bloomberg (USA) - A new study with involvement of the Potsdam Institute for Climate Impact Research (PIK) shows: increasing floods worsened by global warming could lead to regional production losses worldwide - with effects that might propagate through the global network of trade and supply chains. Besides the rapid reduction of greenhouse gas emissions, "the answer is not isolationism", says PIK-scientist Anders Levermann who contributed to the study. "The answer is getting better trade relations." Source: Bloomberg (USA), 28.05.2018.

KBIA (USA) - In a new Worldbank report, Southern Asia is identified as one of the world's most vulnerable regions to migration forced by climate change impacts. Along with a number of other economical and social factors, water scarcity and yield failures become more and more important drivers. PIK-scientist Jacob Schewe contributed to the report and joins the program on "Climate Change in South Asia" by Global Journalist aired by the award-winning US radio station KBIA.

"Hot Nature Weakens and Wilts"
Radio Ecoshock (Canada) - The Atlantic Meridional Overturning Circulation (AMOC) was found weaker today than any time before in over 1000 years by a new study conducted by an international team of scientists around Levke Caesar from the Potsdam Institute for Climate Impact Research (PIK). Hundreds of millions of people on both sides of the Atlantic could be affected by the climatic consequences of an alteration of the major system of ocean circulations.

"The oceans' circulation hasn't been this sluggish in 1,000 years. That's bad news."
The Washington Post (USA) - Scientific analysis of sea surface temperature data provides new evidence that the major ocean circulation called Atlantic overturning has slowed down by about 15 percent in the last 70 years. Stefan Rahmstorf from the Potsdam-Institute for Climate Impact Research (PIK) tells the major US newspaper The Washington Post, that this was "something that climate models have predicted for a long time, but we weren't sure it was really happening. I think it is happening, [...] And I think it's bad news." Climate change is a prime suspect for the worrying weakening. Source: The Washington Post (USA), 11.04.2018.

"Rising sea levels come at steeper cost"
Physics World (UK) - Our climate action now has substantial impacts for centuries. A new study from the Potsdam Institute for Climate Impact Research (PIK) and other international institutions found that "every delay in peaking emissions by five years between 2020 and 2035 could mean an additional 20 cm of sea level rise in the end", as lead author Matthias Mengel explains. "The Paris Agreement calls for emissions to peak as soon as possible. This might sound like a hollow phrase to some, but our results show that there are quantifiable consequences of delaying action" adds PIK-scientist Carl-Friedrich Schleussner, co-author of the study.
