New method to better understand much-employed self-learning Artificial Intelligence

New method to better understand much-employed self-learning Artificial Intelligence

11/04/2019 - Recent advancements in Artificial Intelligence (AI) research result from the combination of deep neuronal networks and reinforcement learning. In the latter, agents are able to learn rewarding behaviours in unknown environments by an iterative trial-and-error behaviour update process. But this process is not yet fully understood. Reinforcement learning agents are a specific area of AI. As AI can have a big impact on society, a better understanding AI systems is crucial to assess potential challenges and risks. Already today, AI is employed to steer cars, manage production lines, or even draft texts. A team of scientists from the Potsdam Institute for Climate Impact Research has developed a new method to investigate those algorithms using insights from statistical physics. Published in the journal Physical Reviews E, their insights can help to improve the design of large-scale AI reinforcement learning systems.

German Advisory Council on Global Change issues Report: Digital change and successful climate protection can only succeed together

German Advisory Council on Global Change issues Report: Digital change and successful climate protection can only succeed together

11/04/2019 - The ongoing digitalisation and the transformation towards more sustainability and climate protection can only succeed together, states the German Advisory Council on Global Change (WBGU) in its report "Towards Our Common Digital Future". Digitalisation must be put at the service of sustainable development. If this fails, digital change could further exacerbate climate and environmental problems, for example by increasing resource and energy consumption, the council’s experts warn, including Hans Joachim Schellnhuber, Director Emeritus of the Potsdam Institute for Climate Impact Research (PIK). The report was presented to the German Federal Minister of Education and Research Anja Karliczek and the German Federal Minister of the Environment Svenja Schulze in Berlin.

Make climate impact models fit for extreme events, says study

Make climate impact models fit for extreme events, says study

01/03/2019 - Computer models used for assessing future global climate change risks are doing a good job when it comes to gradual changes, but they may be underestimating the severity of extreme events, finds an international team of scientists led by the Potsdam Institute for Climate Impact Research. They compared, for the first time, a large number of different simulations across sectors with the measured impacts of the 2003 European heat wave. In reality, the heat wave and drought in 2003 hit agriculture and ecosystems hard, and caused thousands of excess fatalities. These extreme impacts were not captured by most of the simulations. This means that there is an urgent need to develop models that better represent impacts from climate extremes. It also means that unmitigated global warming might be more costly and stabilizing our climate hence economically more rewarding than so far estimated.

Monsoon forecasting for improved climate resilience in Sri Lanka

Monsoon forecasting for improved climate resilience in Sri Lanka

19/02/2019 - Monsoon prediction specialist Elena Surovyatkina from the Potsdam Institute for Climate Impact Research (PIK) recently visited Sri Lanka on Government invitation for talks with representatives of the Ministry of Irrigation and Water Resources, the Ministry of Disaster Management, the Meteorological Department and the General Sir John Kotelawala Defence University. Sri Lanka is a tropical insular state east of the southern tip of the Indian subcontinent. In a warming world, floods or droughts during monsoon period could become more frequent, potentially affecting millions of people. Long-term monsoon forecasts could help make Sri Lanka more climate resilient.

Time series networks: “Transforming messy big data into something comprehensible”

Time series networks: “Transforming messy big data into something comprehensible”

04/02/2019 - A first in-depth review of time series networks has now been published by an international team of scientists in Physics Reports, one of the leading journals in its field. While both nonlinear time series analysis and complex networks theory are widely considered to be established areas of research, the combination of both approaches has now become an active field of scientific progress. The review discusses in great detail on more than 80 pages three main approaches. Examples that the authors touch upon reach from climatology to neurophysiology and economics. The team of authors is led by Yong Zou from East China Normal University, Shanghai, while all other authors are from the Potsdam Institute for Climate Impact research, including Jürgen Kurths, co-chair of the department for Complexity Science.

Ranking: the climate papers most featured in online media

Ranking: the climate papers most featured in online media

12/01/2019 - Scientific publications from the Potsdam Institute for Climate Impact Research scored well in online and social media. The UK online news outlet Carbon Brief just published an interesting ranking based on Altmetric that - while it is certainly not comprehensive since the data base is not comprehensive - gives some indications which papers in 2018 have been most referred to in the public. Of course, the list most prominently features the "Trajectories of the Earth System in the Anthropocene" (or 'Hothouse Earth') paper by, amongst others, PIK's Johan Rockström, Jonathan Donges, Ricarda Winkelmann, and Hans Joachim Schellnhuber published in PNAS. Carbon Brief calls it the climate science paper that scored top in media. Looking at all scientific publications in 2018 - hence beyond the field of climate research - it still is the fifth most talked-about of all journal papers, which is enormous.
