Worldbank report with PIK: climate change can trigger migration of millions

Worldbank report with PIK: climate change can trigger migration of millions

19/03/2018 - Climate change is a driver of future migration – in a worst-case scenario, it could force more than 100 million people out of their homes by 2050. This is shown by a groundbreaking Worldbank report, co-authored by scientists from the Potsdam Institute for Climate Impact Research (PIK). Subsaharan Africa and Southern Asia are among the most affected regions, to a lesser extent also Latin America. Water scarcity and yield failures are, along with a number of other economical and social factors, becoming more and more relevant for migration within countries. This so-called internal migration is the subject of the report. However, rapid reductions of greenhouse-gas emissions can reduce this future migration by up to 80 percent, according to the report.

Coalition-building for pricing CO2 could make sense even for egoistic countries

Coalition-building for pricing CO2 could make sense even for egoistic countries

02/26/2018 - Even countries that tend to act in an egoistic way in the long run have an incentive to participate in international climate stabilization pathways and couple CO2 pricing systems, a new game-theoretical study shows. Yet they might only do this if pioneer coalitions for pricing greenhouse gas emissions make the first steps. If this is the case, the egoistic countries temporarily enjoy the benefits of avoided climate change without paying for it, but in the longer term can join the pioneers and link to their already established models of CO2 pricing. Forming larger and larger coalitions always reaps additional benefits of avoided damages from climate change. These benefits, even though unequally distributed across the coalition members, can be distributed via financial transfers. This makes it attractive to join, even for egoistic countries.

Potsdam-China and back: "When climate projections return home"

02/05/2018 - China's Guanting region is threatened by water scarcity - how water and land can be used sustainably was explored over several years by a German-Chinese team headed by the Potsdam Institute for Climate Impact Research (PIK). Now the scientists published a book on their findings. The researchers applied computer simulations on climate change and water cycles in Brandenburg to the Guanting region. They thereby gained valuable new methodological insights for refining their models - and now bring this back to Germany: a learning process across continents.

Biomass plantations not compatible with planetary boundaries

Biomass plantations not compatible with planetary boundaries

01/22/2018 - Planting trees or grasses on a grand scale in plantations to extract CO2 from the atmosphere - this could make a long-term contribution to climate protection, but it would push the planet beyond ecological limits in other dimensions. A new study by the Potsdam Institute for Climate Impact Research (PIK) in the journal Nature Climate Change now for the first time establishes a connection between ambitious international climate objectives and the more comprehensive concept of planetary boundaries. If biomass plantations in which plants bind carbon dioxide during growth are massively expanded, this would entail enormous risks for areas that are already stressed, such as biodiversity, biogeochemical flows, water resources and land use. According to the study, biomass as a means to capture and store CO2 can therefore only make a limited contribution. In order to stabilize the climate, a rapid reduction of greenhouse gas emissions from the combustion of coal, oil and gas is crucial.

Detecting abrupt transitions – be it in ocean heat or financial markets

Detecting abrupt transitions – be it in ocean heat or financial markets

01/03/2018 - From stock indices to sea surface temperatures, a lot of relevant data comes in the form of time series. Reliable detection of abrupt transitions such as a downswing of stock values or water warming during an El Niño event in the Pacific is obviously important, but most analyses fail to take into account the uncertainties in the data. The challenge is to distinguish sudden changes while being aware of the underlying uncertainties. Although there are a number of change point detection methods, scientists now propose for the first time an approach that accurately represents the time series uncertainties and thus provide a more robust analysis.

ReKliEs-De: Future climate trends in Germany

ReKliEs-De: Future climate trends in Germany

12/11/2017 - More heat-waves and heavy rainfalls, fewer cold spells, an increase in the annual mean temperature by 4°C, this is how the climate in Germany could evolve until the year 2100 in a scenario of unabated climate change - with massive consequences for agriculture and public health. These are the results of the project ReKliEs-De ("Regional Climate Projections Ensemble for Germany") which for the first time estimates current climate projections for the German federal states and river basins. The prospects for Germany in a business as usual scenario are severe - if no active countermeasures will be taken. However, the results also show that if all climate protection agreements will be consistently implemented, the two-degree target agreed in Paris is still achievable.
