In 2010, we published an influential paper in PNAS based on molybdenum isotopes in euxinic shales to suggesting Earth’s oxygen level increased in two steps during the rise of animals and rise of land plants. Now, 14 years later, geochemists have collected far more geochemical data from the geological rock record and developed better models … Read More
In a new study published in One Earth (Cell Press), Aske L. Sørensen and Tais W. Dahl demonstrates that the Earth system tipped into a state of widespread marine anoxia during the Cambrian SPICE event. A self-cascading mechanism involving anoxia-dependent nutrient release from seafloor sediments has been documented regionally and hypothesized to operate globally. The … Read More
We are excited to announce an upcoming Geobiology Symposium titled “The Evolution of Phytoplankton,” featuring two of the world’s leading experts in the field, Professor Andrew H. Knoll from Harvard University and Professor Roger Summons from the Massachusetts Institute of Technology (MIT). This highly anticipated event will take place at the Globe Institute, University of … Read More
In TV2’s Newsroom, Søren Lippert compares Geoengineering with inventions by Gyro Gearloose in Duckburg, and interviews Associate Prof. Tais W. Dahl how we should look at various Geoengineering mitigation strategies and a new research project that test pumping up salt water onto sea ice in the Arctic in the hope that it will create a … Read More
The European Association of Geochemistry has awarded former postdoc in the Geobiology Lab, Feifei Zhang, with the F.G. Houtermans Award. After postdoc years at Yale and in our group, Dr. Feifei Zhang, joined the Faculy as full-time professor at Nanjing University. The Houtermans award recognizes exceptional contributions to geochemistry by an early career scientist. Feifei … Read More
Join our dynamic team at the Globe Institute, University of Copenhagen! We’re on the lookout for a PhD candidate (3 years) and a postdoc (2 years) to become integral members of our Earth History and Geobiology research group. Dive into the exciting Research project, “Natural Carbon Dioxide Removal from a high-CO2 atmosphere,” generously funded by … Read More

You will take part of the research group and work at the forefront of a vibrant geobiological research field. Check out the official posting here . Application deadline is October 9th, 2023. The main focus will be … Read More
The joint Publications Committee of the Geochemical and Meteoritical Societies, the sponsoring societies of GCA have appointed Tais W. Dahl as associate editor for the leading international geochemical journal Geochimica et Cosmochimica Acta. The position will run at least through 2026. Geochimica et Cosmochimica Acta (GCA) is sponsored by the Geochemical Society and the Meteoritical … Read More
Deliberate carbon dioxide removal (CDR) from the atmosphere is necessary to keep globalwarming at safe levels in this century. Enhanced weathering and ocean fertilization are powerfulnatural CDR processes with potentials to counter global warming, but their impact andbiogeochemical consequences upon implementation are uncertain due to limited verification at theglobal scale in the real world. Past … Read More
