Julia Windmiller co-leads the atmospheric measurements on board RV SONNE

Photo Forschungsschiff Sonne

On 27 June 2021, after a 10-day quarantine of the participants, the RV SONNE will set off from Emden under the cruise guidance of Prof. Peter Brandt from GEOMAR in Kiel and co-leader Dr. Julia Windmiller from the Max Planck Institute for Meteorology (MPI-M). The cruise under the name "Mooring Rescue" serves to control and collect scientific…

How climate modelling works — Johann Jungclaus involved in establishing new website on climate simulations

Graphic Project logo Deutsches Klima-Konsortium

Climate neutrality by 2045 is Germany´s goal, and debates on how to get there are in full swing. To achieve it, profound changes are needed. Climate simulations show why this is important. Without them, climate policy remains blind. How climate models work and why they are reliable is explained by the Deutsches Klima-Konsortium (DKK) on the new…

Abrupt CO2 quadrupling: Resolving ocean eddies leads to smaller increase in global mean surface temperature

In a recent study in Geophysical Research Letters, Dr. Dian Putrasahan and colleagues from the department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M), from Universität Hamburg and from the UK MetOffice Hadley Centre investigated the effect of resolving ocean eddies on global mean surface temperature (GMST)…

In a new paper, Veit Lüschow, Jin-Song von Storch and Jochem Marotzke from the Max Planck Institute for Meteorology show that the Atlantic meridional overturning circulation could respond unexpectedly to anticipated future changes in the winds near Antarctica: Besides increasing the northward transport of warm water near the surface, stronger winds…

The Arctic polar vortex response to volcanic forcing of different strengths

Large volcanic eruptions can inject sulfur containing gases into the stratosphere where they build sulfate aerosols. These particles, on the one hand, scatter incoming sunlight away from the Earth, resulting in a temporary global mean surface cooling. On the other hand, they absorb infrared radiation and thereby warm the lower stratosphere. These…

Climate Protection: Deep Decarbonization by 2050 Currently Not Plausible

Today the Hamburg-based Cluster of Excellence “Climate, Climatic Change, and Society” (CLICCS) publishes a new, essential study on climate futures. The study represents the first systematic attempt to investigate whether a climate future with net-zero carbon emissions is not only possible but also plausible. The authors examine plausibility from a…

ESM2025: Earth System Models for the future

ESM2025, an ambitious European project on Earth System Modelling, coordinated by Météo France-CNRM, is now official. The project started on 1 June 2021 and is funded with 11 Mio € from the European Commission's H2020 programme. ESM2025 relies on an international team of 19 European institutes (from seven European countries: Austria, Belgium,…

One step closer to a new generation of Earth System Models

NextGEMS, an ambitious European project to develop a new generation of Storm-resolving Earth System Models (SR-ESMs), is now official.

On May 28, 2021 the EU and 26 partners from 13 European countries and one from Africa (Senegal) signed the grant agreement that will fund NextGEMS as a four year, 11 Mio €, Horizon 2020 project, starting on…

Could the deglaciation of Snowball Earth have started in the mid-latitudes?

A new study, led by scientists of the Max Planck Institute for Meteorology (MPI-M), investigates the question which conditions could have triggered the terminal deglaciation of a hard Snowball Earth. Philipp de Vrese, Tobias Stacke, Jeremy Caves Rugenstein, Jason Goodman and Victor Brovkin found that the thawing of a fully glaciated planet could…
