Being in the right place at the right time is crucial. Clocks help us to coordinate dates and appointments. This is also important for research of the geological past, as it is the only way to reliably reconstruct cause and effect in the climate system. Geological climate archives must therefore be dated as precisely as possible in order to draw reliable conclusions. An international initiative of researchers, to which Dr. Thomas Westerhold from MARUM – Center for Marine Environmental Sciences at the University of Bremen, among others, has made a significant contribution, is now calling for the most important marine climate archives to be dated more precisely than ever before across all regions.

Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in the ocean. In the Proceedings of the National Academy of Sciences, University of California, Irvine researchers report evidence that marine nutrient cycles – essential for sustaining ocean ecosystems – are changing in unexpected ways as the planet continues to warm.
