Julia Windmiller co-leads the atmospheric measurements on board RV 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 measuring buoys in the tropical Atlantic by 15 ocean researchers from GEOMAR as well as atmospheric measurements by 9 participants from MPI-M, the Leibniz…

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

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 website https://www.klimasimulationen.de/. Dr Johann Jungclaus, scientist and group leader at the Max Planck Institute for Meteorology (MPI-M),…

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) response to increasing CO2 concentrations. They find that resolving eddies leads to a 0.1°C smaller GMST increase under abrupt CO2 quadrupling, and…

Claudia Stephan has been accepted into the Elisabeth Schiemann Kolleg

Dr. Claudia Stephan, Minerva Fast Track group leader in the department “The Atmosphere in the Earth System” at the Max Planck Institute for Meteorology (MPI-M) has been accepted into the Elisabeth Schiemann Kolleg of the Max Planck Society. She is the first researcher at MPI-M to be included in this select group of outstanding young female scientists. Claudia Stephan came to MPI-M in May 2018 with a PhD from the University of Colorado, USA. She was awarded a Minerva Fast Track position by…

Only eddy-resolving models capture the complete range of AMOC responses to surface winds

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 in the Southern Ocean might also lead to a drastic weakening of the bottom circulation.

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 temperature anomalies have consequences for atmospheric circulation which are still not well understood.

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 technical-economic perspective, but also with regard to the societal changes necessary for such a future. They conclude that deep decarbonization by…

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, France, Germany, Norway, Sweden, Switzerland and the UK) and an Australian university.

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 September 1, 2021. The project — coordinated by Prof. Bjorn Stevens at the Max Planck Institute for Meteorology (MPI-M) and Dr. Irina Sandu, the team…

FESSTVaL: a field campaign targeted to the detection of small-scale weather phenomena

Like a magnifying glass, FESSTVaL will peer into the internal structure of small-scale weather phenomena, with a particular emphasis on summertime rain storms. The field campaign will take place from mid-May through August, around the Meteorological Observatory Lindenberg - Richard-Aßmann-Observatory of the German Meteorological Service (DWD), in the district Oder-Spree near Berlin, and will deploy around 250 supplementary instruments to monitor the atmosphere and the land surface.

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 have started at comparatively low atmospheric CO2-levels as a result of low surface albedos in the mid-latitudes due to a combination of high dust…

Response of high-latitude ecosystems to temperature overshoot scenarios

High-latitude soils contain almost twice as much carbon as the atmosphere, and the fate of this frozen organic matter under ongoing climate change is not well understood. Two recent studies led by scientists of the Max Planck Institute for Meteorology (MPI-M) are focused on the response of high-latitude ecosystems to temperature overshoots – climate pathways that are becoming more and more likely if we are to stabilize global temperatures at a desirable level. Philipp de Vrese, Victor Brovkin,…
