Global temperature modes shed light on the Holocene temperature conundrum

One of the hot topics in climate research is the evolution of the global mean temperature of the last several thousand years, the period from the so-called early and mid-Holocene, some 9000 to 8000 years ago, to the late Holocene, the time where we live in. Geological reconstructions of the global mean annual temperature evolution during this…

Smaller land carbon feedback in the new MPI Earth System Model

In two recent studies, scientists of the Max Planck Institute for Meteorology (MPI-M) analyzed the feedback between CO2 and climate using Earth System models (ESM) in the Climate Modelling Intercomparison project, phase 6 (CMIP6). The authors Prof. Victor Brovkin, Dr. Tatiana Ilyina, Prof. Julia Pongratz, and Dr. Thomas Raddatz found that the…

Substantial biases persist in CMIP6 simulations of tropical precipitation

A group of scientists mostly from the Max Planck Institute for Meteorology (MPI-M) studied the representation of tropical precipitation by models participating in the Coupled Modelling Intercomparison Projects (CMIP). Their analysis of output from models spanning twenty years of development over three CMIP phases, found little general improvement…

Global warming leads to higher storm surges in the German Bight

Abb. 1: Simulierte Veränderung der Sturmfluthöhe einer statistisch alle 50 Jahre erwarteten Sturmflut relativ zum jeweiligen mittleren Meeresspiegel.

A new study in Climate Dynamics by Andreas Lang and Uwe Mikolajewicz from the Department "The Ocean in the Earth System" at the Max Planck Institute for Meteorology (MPI-M) shows that the intensity of extreme storm surges on the German North Sea coast is projected to increase under rising greenhouse gas emissions. With the help of numerical…

New climate simulations for the “Coupled Model Intercomparison Project”

Abb. 1: Zeitreihe der globalen mittleren Oberflächenlufttemperatur relativ zur Referenzperiode 1995 bis 2014, wie sie von MPI-ESM1.2 LR, HR und ER simuliert wurde, zusammen mit der globalen mittleren Oberflächentemperatur aus dem HadCRUT4-Beobachtungsdatensatz (gelb) für die vorindustriellen Kontrollsimulationen (grau, schwarz) und vier CMIP6-Szenarien (Farben). (Abbildung: K. Meier-Fleischer und M. Böttinger, DKRZ).

Researchers around the globe are using numerical climate models in an attempt to find answers to the question: How would global warming change our world? Earth’s climate is extremely complex and difficult to model. Each climate model has its specific strengths and weaknesses. In order to estimate the bandwidth of possible future climate…

How cold is it under thunderstorms? Measuring cold pools in Hamburg

Scientists at the Universität Hamburg and the Max Planck Institute for Meteorology (MPI-M) are measuring a weather phenomenon that we all know well, especially these days: thunderstorms. The weather is warm and nice, and suddenly a thunderstorm pops in the sky and produces extreme downpours for a brief instant. During such events, the air…
