Climate protection: Land use changes cause the carbon sink to decline
Forests can bind large amounts of carbon on the land surface. In this way, they decisively contribute to reducing net greenhouse gas emissions. For some areas, however, data are still lacking. In East Europe, in particular, the network of installed measurement stations is very loose, such that little has been known about carbon flows and their drivers there. “But East European forests have a great potential as a long-term carbon sink,” says Karina Winkler from the Atmospheric Environmental Research Department of the Institute of Meteorology and Climate Research (IMK-IFU), KIT’s Campus Alpine in Garmisch-Partenkirchen. “Political upheavals in East Europe, however, have caused big changes of land use. Moreover, climate change there increasingly affects the forests. This unique interaction of socioeconomic and climatic factors influences the carbon sinks.”

What began as a theory in the 1890s — that industrial emissions of carbon dioxide could increase global temperatures — had progressed to a scientific fact a century later. Scientists across a range of disciplines are studying the impact of the still-growing concentration of carbon dioxide and other so-called “greenhouse gases” in the atmosphere as they call for industrial and governmental policies to slow, then halt, the warming of the planet.
