The Ocean Physics Behind Net Zero

Gresham College Lectures

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.

A lecture by Myles Allen recorded on 31 January 2023 at Barnard's Inn Hall, London.
