In a new study, a team of researchers around Alexander Winkler and Prof Victor Brovkin from the department “The Land in the Earth system” at the Max Planck Institute for Meteorology (MPI-M) show that most Earth system models (ESM) underestimate the response of Arctic plant productivity to rising atmospheric carbon dioxide (CO2) concentration. These models, which serve as the scientific basis for the IPCC Assessment Reports, likely also underestimate future carbon uptake by photosynthesis - a…
A new working group on drivers of tropical circulation has been introduced in the department "Atmosphere in the Earth System" at the Max Planck Institute for Meteorology (MPI-M). The group is led by Dr Ann Kristin Naumann and is a joint project between the MPI-M and the Universität Hamburg. The group is also part of Hamburg's new cluster of excellence on "Climate, Climatic Change, and Society" (CLICCS).
The MiKlip project, led by Prof Jochem Marotzke and coordinated by Dr Sebastian Hettrich at the Max Planck Institute for Meteorology, has made its decadal climate forecasts for 2019–2028 available online.
A new study, published in Nature by German scientists from Jena and Hamburg, with lead author Prof. Markus Reichstein, managing director at the Max Planck Institute for Biogeochemistry (MPI-BGC) and co-author Prof. Bjorn Stevens, director and head of the department “The Atmosphere in the Earth System” at the Max Planck Institute for Meteorology (MPI-M), shows that artificial intelligence (AI) can help to better understand climate and the Earth system. The scientists show that specifically deep…
In a study performed within the BMBF-funded MiKlip project ALARM Dr Matthew Toohey from GEOMAR Helmholtz Centre for Ocean Research in Kiel, Dr Hauke Schmidt and Dr Claudia Timmreck from the Max Planck Institute for Meteorology in Hamburg, and Prof Kirstin Krüger from the University of Oslo have investigated together with ice core and tree ring experts from Switzerland, the UK and the USA how explosive extratropical eruptions impact the surface climate in the Northern Hemisphere. The results…
Recently, Prof Jochem Marotzke, managing director at the Max Planck Institute for Meteorology (MPI-M) and head of the department “The Ocean in the Earth System” published in a recent paper in WIREs that even if CO2 emissions fall after 2020, there is a one-in-three chance that global surface warming will speed up until 2035 instead of slowing down, and we cannot predict which state we will be in.
Peter Korn, scientist in the department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M), presents the current development of the ocean model ICON-O in two new publications. In the first study “A Structure Preserving Discretization of Ocean Parametrizations on Unstructured Grids”, a new solution to a twenty-year-old problem of ocean modeling is found and the development of ICON-O completed. In the second study „A conservative discretization of the…
The Max Planck Institute for Meteorology (MPI-M) attracts many young postdoctoral scientists to come to Hamburg, Germany, to do their research and take their first career steps here. Usually, they apply for scientific positions in projects and get funded by project money, but there is also a group of PostDocs who have successfully applied for their own, independent funding to come to MPI-M. A particularly attractive funding option is the Humboldt Research Fellowship for Postdoctoral…
To further improve our fundamental understanding of the effects of the topography and rotation on the climate, a team of scientists performed and analyzed simulations with the Max Planck Institute Earth System Model (MPI-ESM), in which the rotation of Earth is reversed (retrograde). Their findings were recently published in Earth System Dynamics.
The rotation of Earth shapes our climate system in various ways: It controls the major wind directions, lets the weather systems swirl, and, together with the topography, it creates strong ocean currents. Many other features of the climate system, like the monsoon systems and the meridional overturning circulation in the ocean arise from complex interactions within the climate system, and their exact dependency on the topography is hard to pinpoint. To further improve our fundamental…
Dr. Dirk Notz, from the department "The Ocean in the Earth System", talks about the world climate conference in Bonn. The interview focuses on climate change, politics and economics (in German).
