Шаблон:Short description Шаблон:EngvarB Шаблон:Use dmy dates Шаблон:Infobox scientist Gabriele Clarissa Hegerl Шаблон:Post-nominals[1] (born 9 January 1962)[2] is a German climatologist.[2] She is a professor of climate system science at the University of Edinburgh School of GeoSciences.[3] Prior to 2007 she held research positions at Texas A&M University and at Duke University's Nicholas School of the Environment, during which time she was a co-ordinating lead author for the Intergovernmental Panel on Climate Change (IPCC) Fourth and Fifth[4] Assessment Report.[5][6]

Early life and education

Hegerl was born on 9 January 1962 in Munich, Germany.[2] She gained undergraduate and graduate degrees at the Ludwig Maximilian University of Munich, finishing with a PhD in 1991,[2][7] with a thesis using a numerical solution of the Navier–Stokes equations using boundary conditions.[7]

Research and career

Hegerl's research[8] [9][10] in the natural variability of climate and changes in climate due to natural and anthropogenic changes in radiative forcing (such as greenhouse warming, climate effects of volcanic eruptions and changes in solar radiation). Hegerl has also led well-known research on the attribution of modern climate change to anthropogenic greenhouse gas emission.

She led a 2006 study examining climate sensitivity, then commonly accepted as 1.5 to 4.5K in response to a doubling of atmospheric Шаблон:Co2, to review observational studies suggesting that climate sensitivity could be as much as 7.7K or even exceed 9K. By using large-ensemble energy balance modelling to simulate temperature responses to historic changes in the radiative forcing effect of solar changes, volcanic eruptions and greenhouse gases, and comparing this to climate reconstructions, they produced an independent estimate that climate sensitivity was probably within the range of 1.5 to 6.2K.[9] In an interview with The Washington Times, Hegerl said "Our reconstruction supports a lot of variability in the past".[11]

She is a co-ordinating lead author on the IPCC Fourth Assessment Report for Working Group I in the chapter on "Understanding and Attributing Climate Change".[12] Her 2006 reconstruction was cited in the chapter on "Paleoclimate" in support of the conclusion that the 20th century was likely to have been the warmest in the Northern Hemisphere for at least 1,300 years.[13]

She was a member of a team which reviewed recent reconstructions of the temperature record of the past 1000 years, and in 2007 published their own reconstruction from proxies, finding that the maximum pre-industrial temperature in 1,000 years had been significantly exceeded by recent instrumental temperatures.[10]

Honours and awards

In 2013, she was elected a Fellow of the Royal Society of Edinburgh (FRSE)[20] and in 2017 she was elected a Fellow of the Royal Society (FRS).[1] In 2018 she was made an honorary Doctor of Science by Leeds University.[21] In 2016, Professor Hegerl won the Hans Sigrist Prize "for her groundbreaking scientific work in this year’s prize field, 'The Human Fingerprint on the Earth System'"[22] In 2018 she became a member of the German Academy of Sciences Leopoldina.[23]

Personal life

Hegerl was married to Thomas Crowley and was later widowed. She has two sons, born in 2000 and 2003.[2]
