”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.

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.

Indian monsoon can be predicted better after volcanic eruptions
09/18/2020 - Large volcanic eruptions can help to forecast the monsoon over India – the seasonal rainfall that is key for the country’s agriculture and thus for feeding one billion people. As erratic as they are, volcanic eruptions improve the predictability, an Indian-German research team finds. What seems to be a paradox is in fact due to a stronger coupling between the monsoon over large parts of South and South-East Asia and the El Niño phenomenon after an eruption. Combining data from meteorological observations, climate records, computer model simulations, and geological archives such as tree-rings, corals and ice-cores from past millennia of Earth history, the researchers found that a synchronization of the monsoon with the strongest mode of natural climate variability, the El Niño, makes it easier to anticipate the strength of seasonal rainfall in the Indian subcontinent.
