Ulrike Lohmann

Lohmann supports the young people striking to draw attention to climate change, and in 2019 she was one of the scientists signing on to a statement on the school protests for climate protection to draw attention to the climate crisis.

Lohmann's research centers on the interactions between global warming, aerosols, and cloud formation. Her early research modeled the influence of cirrus clouds on climate, which she continued in her use of the ECHAM model. Her research also considers the global indirect aerosol effects and the connection to climate change. She also deals with the possibility of geoengineering by thinning cirrus clouds. In the 2017 Science article, she notes "for the time being, cirrus cloud thinning should be viewed as a thought experiment that is helping to understand cirrus cloud–formation mechanisms".

She is one of the lead authors on the chapters on Clouds and Aerosols in the fourth and fifth assessment reports of the Intergovernmental Panel on Climate Change (IPCC), and she shared in the 2007 Nobel Peace Prize for her contribution to the IPCC reports.

Lohmann comes from Kiel as the daughter of a teacher and a politician in the Social Democratic Party of Germany. She did a volunteer year in an SOS Children's Village in Nigeria, and then studied ethnology and geography. Inspired by environmental reports on climate change, she studied meteorology at the University of Mainz from 1988 to 1993. She received her doctorate in 1996 at the Max Planck Institute for Meteorology. She initially worked as assistant professor and associate professor for atmospheric sciences at Dalhousie University. She has been a full professor of atmospheric physics at the Institute for Atmosphere and Climate at ETH Zurich since 2004.
