Marie Corinne Lyne Le Quéré^[1] CBE FRS (born July 1966) is a Canadian scientist. She is Royal Society Research Professor of Climate Change Science at the University of East Anglia^[2] and former Director of Tyndall Centre for Climate Change Research. She is the chair of the French High Council on Climate and member of the UK Climate Change Committee. Her research focuses on the interactions between the carbon cycle and climate change.^[3]

Le Quéré received her B.Sc. in physics from University of Montreal, an M.S. in Atmospheric and Oceanic Sciences from McGill University, and a Ph.D. in oceanography from University of Paris VI.^[4]

Le Quéré was born in Quebec in 1966 and as a child spent her camping holidays in the national parks of Eastern Canada which fostered her interest in the natural world.^[5][6] She left high school in 1984 and enrolled for a course in general studies in a small university near to her home in Gatineau prior to transferring to the University of Montreal to study physics.^[6]

Le Quéré later became a British Citizen and holds both French and Canadian passports. She is now married to her second husband and has a daughter from her first marriage, Marianne, who she raised partly as a single mother.^[6]

On 3 February 2023, Le Quéré was a guest on BBC's Desert Island Discs on Radio 4 (presented by Lauren Laverne). As an imaginary Castaway she chose a mask and snorkel as her luxury items and, for her favourite disc, La Vida Es Un Carnaval by Celia Cruz. For her book, she chose World Atlas of the Oceans^[7] by Dave Monahan.^[5][8]

She was co-chair of the Global Carbon Project (GCP) from 2009 until 2013.^[9] Within the GCP, she initiated and directed for over a decade the annual publication of the Global Carbon Budget.^[10][11] During 2014-2017 she has been a member of the Scientific Committee of the Future Earth platform for sustainability research.^[12][4] She is author of the 3rd, 4th and 5th assessment reports of the Intergovernmental Panel on Climate Change. She conducted research at Princeton University in the US (1992–1996), at the Max Planck Institute for Biogeochemistry in Germany (2000–2005), and jointly between the UEA and the British Antarctic Survey in the UK (2005–2010).

In 2012, Le Quéré was awarded the Claude Berthault award from the French Academy of Sciences,^[13] the first Copernicus medal of the Copernicus Gesellschaft e.V. in 2013/2014,^[14] and was the annual Bolin lecturer in Stockholm University in 2014.^[15]

In 2015, she received a Blaise Pascal Medal for Earth and Environmental Sciences from the European Academy of Sciences^[16] and the Grande Médaille Albert 1er de Monaco, Science section.^[17]

In 2016, Le Quéré was elected a Fellow of the Royal Society.^[18]

In 2016, she was listed among the 20 "women making waves in the climate change debate" on the Road to Paris.^[19]

In 2019, Le Quéré was appointed Commander of the Order of the British Empire (CBE) in the 2019 Birthday Honours for services to climate change science.^[1]

In 2019, she also won the Prince Albert I Medal^[20] and was made a Chevalier of the French Legion of Honour.^[21]

In 2020, she received the Heineken Prize for Environmental Sciences for her interdisciplinary research on the interactions between climate change and the carbon cycle.^[22]
