Vergangene 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.

VeWA is coordinated by Prof. Wolfgang Müller and Prof. Silke Voigt, Goethe University Frankfurt

We're recruiting!

As part of VeWA, eight PhD projects and four postdoctoral opportunities will become available (planned start date late May/early June 2020) in the broad area of late Cretaceous/Paleogene palaeoceanography, palaeoclimatology, and biosphere reconstruction, including marine and terrestrial focused data-driven projects, climate modelling, and outreach. Details of the individual projects are given below.

Project group A - Marine palaeoclimate/palaeoenvironment: Data-driven projects with a focus on palaeoceanic and palaeoclimate reconstruction using novel and traditional geochemical proxies in marine carbonate archives

Project group B - Terrestrial palaeoclimate/palaeoenviornment: Data projects utilising carbonate and phosphate geochemistry, and sedimentology for Paleogene climate reconstruction and climate-mammal interaction

Project group C - Modelling and Outreach: Cretaceous and Paleogene climate and vegetation modelling, and a dedicated outreach iniative

Application deadlines from 2nd March 2020 onwards (see project pages below)

Start date 1st May 2020 or soon thereafter

Reliable sea surface temperatures and latitudinal temperature gradients for determining late Cretaceous and Paleogene polar amplification
