Dear Geo.X colleagues,
We cordially invite you to join a small two-day research workshop on "Solar-Planetary Coupling Effects on the Climate Evolution of Earth and other Planets" funded by Geo.X and hosted at PIK. It takes place on
Thursday 15 May to Friday 16 May 2025
at the Potsdam Institute for Climate Impact Research (PIK), Telegrafenberg, Building A31 (Große Kuppel).
Workshop summary:
Paleoclimate research helps us to understand the Earth’s past climates but also to assess the risks of future climate change. As the solar activity was very different in the past, the changes in solar-planetary coupling need to be considered. The key factors to consider are changing solar irradiance and radiation from outer space, changing solar wind and interplanetary magnetic field (IMF), as well as varying strength and shape of the Earth’s own magnetic field. Especially on geological timescales, these factors may cause changes in atmospheric composition, chemistry and dynamics, e.g., in stratospheric ozone that is vital to the biosphere. Different interaction regimes between solar wind/IMF and the Earth’s/planetary magnetic field may accelerate the loss of atmospheric particles into space, change thermal energy input into the atmosphere, or enhance plasma outflow from the ionosphere. Enhanced precipitations of relativistic particles into the atmosphere may affect NOx formation/chemistry and deplete stratospheric ozone. Due to multi-disciplinary nature of the topic, communication between different institutions, within the local Geo.X network and worldwide, are vital. We organize a two-day workshop to bring together experts working on paleoclimate problematics and climate-relevant solar-planetary coupling topics to exchange expertise, identify key physical processes involved, and to plan joint publications and funding proposals.
Please note that we can host only a limited number of participants. Please indicate your interest in attending via our registration page at eveeno.com/geox_may_2025, where you can add a few sentences on why you'd like to participate and how your expertise contributes to the aims of the workshop. We look forward to hearing from you!
