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.

Adaptation now: River flood risks increase around the globe under future warming
11/01/2018 - Rainfall changes caused by global warming will increase river flood risks across the globe. Already today, fluvial floods are among the most common and devastating natural disasters. Scientists have now calculated the required increase in flood protection until the 2040s worldwide, breaking it down to single regions and cities. They find that the need for adaptation is greatest in the US, parts of India and Africa, Indonesia, and in Central Europe including Germany. Inaction would expose many millions of people to severe flooding.

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.
