Caring for the future is key for cooperation to prevent climate collapse: study

Caring for the future is key for cooperation to prevent climate collapse: study

20/05/2020 - How much decision-makers care about the future and not just the present is one key factor for whether or not they take action to stabilize our climate. Another one is how severe they assume the impacts of climate collapse to be. However, the number of actors is decisive – for instance the number of relevant countries, since efforts to reduce greenhouse gas emissions have to be international to add up to the amount needed to prevent a crisis. This is shown by a novel mathematical study. It finds a strong effect of diffusion of responsibility in scenarios with large numbers of actors. The study combines game theory and learning dynamics to explore which options for enhanced political cooperation should now urgently be studied empirically.

Delayed monsoon onset in Central India: early warning forecast

Delayed monsoon onset in Central India: early warning forecast

12/05/2020 - Summer Monsoon in Central India will likely begin between 18th and 26 of June, according to the new early forecast developed at the Potsdam Institute for Climate Impact Research (PIK). Led by PIK expert Elena Surovyatkina, the Monsoon forecast method showed to be successful already four years in a row. With global warming the monsoon is changing, breaking well-established “rules” of the phenomenon and thus becoming more unpredictable. A raising demand for a new understanding of the Indian Monsoon in order to be better prepared makes long-term forecasting even more important.

Novel network analysis confirms: #stayathome helps limit virus mutations

Novel network analysis confirms: #stayathome helps limit virus mutations

16/04/2020 – Both the virus diseases of the 2013 Ebola regional epidemic and the current COVID-19 global pandemic have seen virus mutations between hosts – a normal phenomenon with the potential to turn viruses even more harmful. A team of scientists including researchers from Humboldt University and Potsdam Institute for Climate Impact Research has now employed advanced mathematical models to explore these dynamics. Their findings confirm public health responses like suspending long-haul travel, but also the call to stay at home. Further, they underline the importance of closely tracking genetic mutations during virus outbreaks to facilitate crisis response.

The Antarctica Factor: model uncertainties reveal upcoming sea level risk

The Antarctica Factor: model uncertainties reveal upcoming sea level risk

Sea level rise due to ice loss in Antarctica could become a major risk for coastal protection even in the near term, scientists say. Within this century already, due to Antarctica alone global sea level might rise up to three times as much as it did in the last century. This is a finding of an exceptionally comprehensive comparison of state-of-the-art computer models from around the world.

Climate costs smallest if warming is limited to 2°C

Climate costs smallest if warming is limited to 2°C

27/01/2020 - Climate costs are likely smallest if global warming is limited to 2 degrees Celsius. The politically negotiated Paris Agreement is thus also the economically sensible one, Potsdam researchers find in a new study. Using computer simulations of a model by US Nobel Laureate William Nordhaus, they weight climate damages from, for instance, increasing weather extremes or decreasing labour productivity against the costs of cutting greenhouse gas emission by phasing out coal and oil. Interestingly, the economically most cost-efficient level of global warming turns out to be the one more than 190 nations signed as the Paris Climate Agreement. So far however, CO2 reductions promised by nations worldwide are insufficient to reach this goal.

Artificial Intelligence: applying ‚Deep Reinforcement Learning‘ for sustainable development

Artificial Intelligence: applying ‚Deep Reinforcement Learning‘ for sustainable development

20/12/2019 - For the first time, a specific way of machine learning has been used to find novel pathways for sustainable development. So far, the so-called 'Deep Reinforcement Learning' has mostly been used to make computers excel in certain games, such as AlphaGo, or navigate robots through rough terrain. Now, scientists from the Potsdam Institute for Climate Impact Research developed a mathematical framework combining recently developed machine learning techniques with more classical analysis of trajectories in computer simulations of the global climate system and the global economy. The results, published in the interdisciplinary journal on nonlinear phenomena 'Chaos', are promising.

Breaking the rules: Monsoon and climate change

Breaking the rules: Monsoon and climate change

26.06.2019 - With global warming the Monsoon is changing, breaking well-established “rules” of the phenomenon, becoming more and more erratic and unpredictable. Close to half of the global population depends on monsoon rainfall. For the fourth year in a row, Elena Surovyatkina from the Potsdam Institute for Climate Impact Research (PIK) successfully predicted the onset of the Indian Summer Monsoon in the central part of India more than a month in advance with a new forecast method. This method accounts for climate change effects and hence makes forecasting possible.
