Myles Allen is Head of Atmospheric, Oceanic and Planetary Physics in the Department of Physics, University of Oxford, and Professor of Geosystem Science in the School of Geography and the Environment.

His research focuses on how human and natural influences on climate contribute to climate change and risks of extreme weather. In 2005, Allen introduced the notion of a finite carbon budget, implying net zero emissions of carbon dioxide are necessary to halt global warming. He has been working on the implications ever since, most recently on the case for Geological Net Zero, or a balance between ongoing production of carbon dioxide from geological sources with carbon dioxide capture and geological storage.

Myles has served on the Intergovernmental Panel on Climate Change, most recently as a Coordinating Lead Author on the IPCC Special Report on 1.5°C. He was awarded the Appleton Medal and Prize from the Institute of Physics “for his important contributions to the detection and attribution of human influence on climate and quantifying uncertainty in climate predictions", featured on the BBC’s “Life Scientific” as “the physicist behind net zero”, was awarded a CBE “for services to climate change attribution, prediction and net zero” and is a Fellow of the Royal Society.
