New method for evaluating Earth System Models

In a new study published in Climate of the Past and highlighted by the journal, Anne Dallmeyer, Victor Brovkin and Martin Claussen from the department "Land in the Earth System" at the Max Planck Institute for Meteorology (MPI-M) have developed a method to uniformly "biomize" vegetation distributions calculated by Earth System models, i.e. to...

Increased AMOC slowdown in high-resolution models

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)...

Shifting winds weakened the recent Southern Ocean CO2 absorption

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.

Similar to a fizzy...

Cause for variability in Arctic sea ice clarified

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.

Contribution to understand the long‐term response of the ocean carbon cycle to climate change

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...

New estimates of the future effect of air pollution on Earth´s radiation budget

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...
