The human reality of heat waves | Eunice Lo | TEDxBristol

About this video

Climate scientist Eunice Lo turns the data on heatwaves into something human: not distant numbers, but our sleep, our health, and the people we love. A sobering but hopeful look at why we have to act now, and where she still finds reason for hope. TEDxBristol 2025 was held at We The Curious, Bristol's much-loved science centre on the city's historic harbourside, and beautifully filmed and edited by the team at Watch & Learn Productions (watchandlearnproductions.com). This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
