”Highly Cited Scientists 2020” ranking: success for PIK researchers
11/18/2020 – The “Highly Cited Scientists” list once again features a number of PIK researchers. Twelve of them rank in the top 1% by citations for field and publication year in the 2020 Web of Science citation index, which is an indicator of scientific relevance. It is a remarkable success that the listed researchers are almost equally distributed across PIK departments and natural and social sciences. Many of them scored well in the “cross field” category of the ranking. The two Directors on the list, representing two important fields – Johan Rockström with Earth System Science and Ottmar Edenhofer with Economy –, are confirming the overarching result: high level transdisciplinary research earns international recognition.

Ice loss due to warming leads to warming due to ice loss: a vicious circle
10/27/2020 - The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this feedback by exploring long-term if-then-scenarios. If the Arctic summer sea-ice were to melt completely, a scenario that is likely to become reality at least temporarily within this century with ongoing greenhouse gas emissions from burning fossil fuels, this could eventually add roughly 0.2°C to global warming. This is, however, not in addition to IPCC projections of future warming since these already take the relevant mechanisms into account. Still, the scientists could now separate the effects of the ice loss from other effects and quantify it. The 0.2°C are substantial, given that global mean temperature is currently about one degree higher than in pre-industrial times, and governments worldwide agreed to stop the increase well below two degrees.

Stability Check on Antarctica Reveals High Risk for Long-Term Sea-Level Rise
09/23/2020 - The warmer it gets, the faster Antarctica loses ice – and much of it will then be gone forever. Consequences for the world’s coastal cities and cultural heritage sites would be detrimental, from London to Mumbai, and from New York to Shanghai. That’s what a team of researchers from the Potsdam Institute for Climate Impact Research, Potsdam University and New York’s Columbia University has found out in their new study, published in Nature (cover story), on how much warming the Antarctic Ice Sheet can survive. In around one million hours of computation time, their unprecedentedly detailed simulations delineate where exactly and at which warming levels the ice would become unstable and eventually melt and drain into the ocean. They find a delicate concert of accelerating and moderating effects, but the main conclusion is that unmitigated climate change would have dire long-term consequences: If the global mean temperature level is sustained long enough at 4 degrees above pre-industrial levels, Antarctic melting alone could eventually raise global sea levels by more than six meters.
