On the eve of COP28 in Dubai, is the goal of limiting global warming to 1.5°C still alive? What does this mean and is it even possible?

Given warming has reached 1.25°C, increasing at around ¼°C per decade, what happens if we miss our target? While every tenth of a degree matters, passing 1.5°C does not mean an inexorable slide into climate chaos, but every year’s delay increases the clean-up bill for future generations.

This lecture was recorded by Myles Allen on 21 November 2023 at Barnard's Inn Hall, London.
