Bjorn Stevens has been elected as a Fellow of the American Geophysical Union in recognition of his exceptional scientific achievements and leadership qualities.
Hartmut Grassl was awarded the Medal for Art and Science by the Hamburg Senate in recognition of his outstanding scientific achievements and exceptional commitment.
The WIVERN research project has been selected for the European Space Agency's eleventh Earth Explorer satellite mission. WIVERN will provide the first ever global measurements of winds within clouds. Cathy Hohenegger from the Max Planck Institute for Meteorology is involved in this mission, which is scheduled to launch in the early 2030s.
From September 16 to 18, 2025, around 220 ocean researchers have met at the CELLO conference organized by the Max Planck Institute for Meteorology. The contributions covered a wide range of spatial scales and disciplines—all with the aim of better understanding the dynamics of the ocean and its influence on the climate.
In September, Northern Germany becomes the meeting point for the international Earth System Modeling community. Three high-level scientific events, the CELLO Conference and the natESM Focus Workshop on Ocean Biogeochemistry in Hamburg, and the TropEcS Symposium in Bremen will bring together leading experts committed to shaping the future of climate, coastal, and ocean modeling.
Our Values
The Max Planck Institute for Meteorology is committed to the core values of the Max Planck Society. The Max Planck Society is a non-university institution dedicated to fundamental research, predominantly publicly funded. We are a highly diverse group of scientists, students, administrators, technical and support staff, and guests.
Our Values
Keeping global warming below 2°C compared to pre-industrial levels requires future carbon emissions to remain below a certain level. Researchers have quantified how accounting for the carbon released from thawing permafrost reduces estimates of the remaining carbon budgets for 2°C and 3°C of warming.
Clouds influence how much the Earth warms in response to a given increase in atmospheric carbon dioxide. In addition to their extent and brightness, cloud altitude is one of the cloud properties believed to play an important role in this process. Researchers have shown: Although for certain cloud types, altitude might change as a result of global warming, this has little effect on climate sensitivity.

How could deep lakes have existed in the highest mountain range of the Sahara several thousand years ago? An interdisciplinary research group has solved this mystery by revealing that moist air masses from the Mediterranean caused heavy rainfall, which filled some of the mountain's volcanic craters.
Newly developed configurations of the climate model ICON allow for the simulation of decadal-scale climate change at km-scale resolution on the world’s most powerful computing systems. In recognition of this accomplishment, two projects using ICON have been nominated for the Gordon Bell Prize for Climate Modelling.
