Klaus Hasselmann (born October 25, 1931 in Hamburg, Germany) is a German climate scientist, meteorologist and oceanographer. In 2021, he was awarded the Nobel Prize in Physics along with Syukuro Manabe and Giorgio Parisi. Hasselmann received the award for his "innovative contributions to our understanding of complex systems", and for "physical modeling of the Earth's climate, quantifying variability and reliably predicting global warming".

Life and work

Background

Hasselmann was born in Hamburg in 1931. His father Erwin Hasselman was an economist, journalist and publicist, and was politically active for the Social Democrats (SPD) since the 1920s. Due to his father's work in the SPD, the family emigrated to Britain in the middle of 1934 in the first phase of the German Nazi regime - the father feared Germany's new repressive regime. Klaus Hasselmann thus grew up in the UK from the age of two. They lived in Welwyn Garden City north of London, and their father worked as a journalist. Although the Hasselmann family was not Jewish themselves, they lived closely associated with the predominantly Jewish German emigrant community, and they received help from English Quakers when they arrived in England. Klaus Hasselmann went to primary school and to Grammar School in Welwyn Garden City, oh took his A-levels (Cambridge Higher School Certificate) in 1949. Hasselmann has said that he was very happy in England and that English is his first language. His parents returned to Hamburg in 1948, and Klaus followed them when he had completed his A-levels. He was almost 19 years old when he came to his parents in Hamburg in West Germany in August 1949.

Higher education

He received his doctorate in physics from the University of Göttingen in 1957. His doctoral dissertation presented a method for determining the reflection and refraction of shock fronts and random wavelengths.

Physicist

Hasselmann headed the Max Planck Institute for Meteorology in Hamburg, from 1975 to 1999. He is best known for developing what has become known as the Hasselmann model. His work makes it easier to follow and to model the effects and climate patterns of climate change. Hasselmann received the Vilhelm Bjerknes Medal from the European Geosciences Union in 2002 and an honorary medal from the University of Alcalá in 2005. In 2021, he was awarded the Nobel Prize in Physics along with Syukuro Manabe and Giorgio Parisi. Hasselmann received the award for his "innovative contributions to our understanding of complex systems", and for "physical modeling of the Earth's climate, quantifying variability and reliably predicting global warming".
