VeWAVergangene Warmzeiten als natürliche Analoge unserer ,hoch-CO2' Klimazukunft
Past warm periods as natural analogues of our 'high CO2' climate future
VeWA is an interdisciplinary Earth Science project funded by the Hessen State Ministry for Higher Education, Research and the Arts through the LOEWE program and led by scientists from Goethe University Frankfurt, the Senckenberg Biodiversity and Climate Research Center, and the Senckenberg Research Institute and Natural History Museum Frankfurt.
Warm climates of Earth's past
By the end of this century, all but the most optimistic projections suggest that the atmospheric concentration of CO2 will reach a level not seen on Earth for millions of years. The aim of VeWA is to reconstruct the relationship between climate, the biosphere, and Earth surface processes during past warm periods such as the Paleogene and late Cretaceous (~95-35 million years ago). In doing so, the goal is to understand the Earth as a system, and to inform model forecasts of potential future climate states.
