Bjorn Stevens

Bjorn Stevens is Director of the Max Planck Institute for Meteorology (Hamburg, Germany) and a scientific member of the Max Planck Society. His particular interest and expertise is on the question of how clouds and water vapor influence the climate, especially its response (e.g., global warming) to human activities. To this end, his team designs and applies computationally intensive climate simulation systems, carries out field studies and runs analyses of long-term observations. Stevens has ranked among the top 1% of authors in his field on the ISI Highly Cited Researchers list since 2019, and has served as lead principal investigator on the Next Generation Earth Modeling Systems project (Horizon 2020). From 2009-2013, he served as a lead author on the “Clouds and Aerosols” chapter of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Among other honors, he holds the Clarence Leroy Meisinger Award of the American Meteorological Society and has presented the Jule Gregory Charney Lecture of the American Geophysical Union.
