Why is the deep ocean cold? And why does this matter for global warming?
Doing the maths with pipes and plumbing, not computers, we explore how processes that keep the deep oceans at frigid Arctic temperatures also determine how fast the world is warming in response to rising greenhouse gas concentrations – and also explain why it would be so difficult to say when the warming would stop even if we were to stabilize greenhouse gas concentrations at today’s levels forever.

Professor Myles Allen
Frank Jackson Foundation Professor of the Environment (2022-)
Professor Myles Allen took his first degree in Physics and Philosophy, followed by a doctorate in Atmospheric, Oceanic and Planetary Physics, both at the University of Oxford. He has worked at Oxford for most of his career, with early stints at MIT and the UN Environment Programme in Kenya, and is currently Director of the Oxford Net Zero initiative.
He has contributed extensively to the Intergovernmental Panel on Climate Change (IPCC), including as Coordinating Lead Author for the 2018 IPCC Special Report on Global Warming of 1.5°C. He has published extensively on how human and natural influences on climate contribute to observed climate change and extreme weather risk, and the implications for adaptation and mitigation policy.
He was awarded the Appleton Medal and Prize by the Institute of Physics in 2010, and in 2022 a CBE for services to climate change attribution, prediction and net zero.
