Professor Lenton is a founding Director of the Global Systems Institute at the University of Exeter and Chair in Climate Change and Earth System Science. He has more than 25 years research experience, focused on modelling of the biosphere, biogeochemical cycling and climate, and associated tipping points. Tim is renowned for his work identifying climate tipping points, which informed the setting of the 1.5C climate target and associated net zero targets and nationally determined contributions. 

Tim works actively with policymakers and businesses helping them assess the risks of climate change and nature loss as well as highlighting the opportunities for ‘positive tipping points’ that can accelerate desired solutions. In 2023, Professor Lenton led a team of more than 200 people from over 90 organisations in 26 countries to produce the ‘Global Tipping Points Report’, an authoritative assessment of the risks and opportunities of both negative and positive tipping points in the Earth system and society. In September 2024, Professor Lenton will launch a report on positive tipping points in the power, transport and heating sectors.
