# Beate G. Liepert

Beate Gertrud Liepert is a professor at Bard College in the Hudson Valley of New York. Her research focuses on climate variability: inter-annual changes, centennial time scales, the water and energy cycles.

## Education

Beate got her diploma in Meteorology at the Institute of Meteorology and Institute of Bioclimatology and Air Pollution Research, Ludwig Maximilians University of Munich, Germany. In 1995 she obtained a PhD in Natural Science at the Institute of Meteorology, Department of Physics, Ludwig-Maximilians University Munich, Germany.

## Career

Beate pioneered research on global dimming, which is the reduction of atmospheric transparency due to air pollution and inter-decadal cloud changes. She worked on implications of global dimming for climate: how and to what extend air pollution masks global warming, and how air pollution can spin down the hydrological cycle in a warmer and moister world. Some of her theoretical studies deal with climate forcing and feedbacks as studied in models and observations. She developed a climate model evaluation and ranking system that relies on first physical principles and self-consistency. Aerosol and solar radiation measurements in urban, as well as rural environments are also part of her research agenda, as is studying the effects of light quality on plant growths and ecosystems. More recently she started applying her knowledge to solar energy resource assessments and optimizing photovoltaic systems as alternative to fossil fuel and nuclear technologies.
Beate contributed a section on global dimming to the Intergovernmental Panel on Climate Change 4th Assessment Report “Scientific Basis” (chapter 3.4.4.2) that won the 2007 Nobel Peace Prize.
