The Amazon region is a global hotspot of biodiversity and plays a key role in the climate system because of its ability to store large amounts of carbon and its influence on the global water cycle. The rain forest is threatened, however, by climate change as well as by intensified deforestation activities. An international team of researchers that includes scientists from MARUM – Center for Marine Environmental Sciences, the Geosciences Department, the Institute for Environmental Physics of the University of Bremen and the Alfred Wegener Institute, have investigated how a change in Atlantic circulation would impact the Amazon Rain Forest. Their results have now been published in the journal Nature Geoscience.
