On the subject of facts as a political issue. Discussing science under pressure, talk Prof Volker Heinz from the Institute of Cultural Studies in Essen, Prof Jochem Marotzke, Director at the Max Planck Institute for Meteorology in Hamburg and Prof Diethard Tautz, Director at the Max Planck Institute for Evolutionary Biology in Plön.
Scientists from the department "The Ocean in the Earth System" at the Max Planck Institute for Meteorology (MPI-M) have shown in the Journal of Advances in Modeling Earth Systems why the Atlantic Meridional Overturning Circulation (AMOC) slows down significantly when the resolution for the atmosphere in the Earth System Model of the MPI-M (MPI-ESM) is increased.
In a new study, Lydia Keppler and Dr Peter Landschützer from department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M) find that the carbon dioxide (CO2) absorption in the Southern Ocean weakened between 2012 and 2016. The study links shifts in regional winds to this reduced carbon uptake.
Using extensive computer simulations, the scientists Dr Dirk Olonscheck, Dr Thorsten Mauritsen and Dr Dirk Notz from the Max Planck Institute for Meteorology (MPI-M) in Hamburg and the University of Stockholm are now able to explain why the Arctic sea ice varies greatly from year to year. Their results were recently published in Nature Geoscience.
In a new study in Geophysical Research Letters Dr Tatiana Ilyina and Dr Mathias Heinze from the department "The Ocean in the Earth System" at the Max Planck Institute for Meteorology (MPI-M) found that during the Paleocene-Eocene Thermal Maximum (PETM) changes in overturning circulation are key to reproducing the deoxygenation and carbonate dissolution record. The study was picked as a "Research Spotlight" in the journal EOS.
Beginning in May 2019 a new working group on cloud-wave coupling led by Dr Claudia Stephan has joined the department "The Atmosphere in the Earth System" at the Max Planck Institute for Meteorology (MPI-M). Claudia Stephan was awarded a Minerva Fast Track position by the Max Planck Society (MPG). MPI-M congratulates Claudia Stephan!
Almost all IPCC scenarios for 2015 to 2100 show a reduction in the air pollution by anthropogenic aerosols for the future, but their effects on the radiation budget are different. Dr Stephanie Fiedler, scientist in the department "The Atmosphere in the Earth System" at the Max Planck Institute for Meteorology (MPI-M), and her co-authors come to this conclusion in a new study published in Geoscientific Model Development.
The ocean CO2 uptake is predictable for two years in advance, according to new paper in Science Advances by Dr Hongmei Li, Dr Tatiana Ilyina, Dr Wolfgang A. Müller, and Dr Peter Landschützer, all scientists in the department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M).
A team of researchers around Dr. Florian Ziemen in the department "The Ocean in the Earth System" at the Max Planck Institute for Meteorology (MPI-M) found that Heinrich events, climate changes during the last ice age, were caused by a succession of the effects of two mechanisms: iceberg calving, having effects on the ocean, and ice sheet elevation loss, having effects on the atmosphere. Using a novel model setup, they were able to study the relationship between the two individual effects. They…
Observation-based estimates show the oceanic uptake of carbon dioxide is varying substantially in time, largely driven by the variability in the surface ocean CO2 content. A new study by Dr Peter Landschützer and Dr Tatiana Ilyina from the department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M) with co-author Dr Nicole Lovenduski investigates the mechanisms and timescales dominating the marine partial pressure of CO2 (pCO2) variability from 1982 through…
From 20 January through 20 February 2020, the EUREC4A (Elucidating the role of clouds-circulation coupling in climate) field study investigated trade wind clouds in the Tropical Atlantic.
