Soil is the largest natural carbon storage in the world. In Northern ecosystems particularly large amounts of carbon are stored, but they are also particularly strongly affected by global warming. A study recently published in Global Change Biology by an international team led by Michael Bahn of the University of Innsbruck investigated how ongoing warming affects the uptake and release of carbon dioxide in subarctic grassland. The researchers used a geothermally active area in Iceland as a natural "climate chamber."
