She is also an accomplished moderator of high-level debates, guiding panels involving global CEOs, former heads of state, government ministers, military generals and global humanitarian leaders. She has extensive experience at designing and facilitating innovative “safe-space” conversations between global leaders, from small round tables through to major international meetings. A prolific broadcaster, Gabrielle has presented many TV and radio programmes for the BBC.

She has been Climate Change Editor at Nature and Features Editor at New Scientist magazine, and has written very extensively for many international newspapers and magazines, including The Economist, Prospect, The Wall Street Journal and The New York Times. She is author of four books including co-authoring the bestselling book The Hot Topic: how to avoid global warming while still keeping the lights on (2008), which was described by Al Gore as “a beacon of clarity” and by The Times as “a material gain for the axis of good”. She has a PhD from Cambridge University and has taught at both Cambridge and Princeton Universities. 

A self-confessed “ice addict” Gabrielle has made more than a dozen trips to both poles. She has also climbed trees in the Amazon rainforest, swum with piranhas, been sneezed on by a humpback whale, hooked lava out of a live volcano, and flown in zero gravity.


A trained scientist and highly respected author and broadcaster, Gabrielle has dedicated her life to tackling the challenges of climate change. With great expertise and humour, she advises governments and companies at the highest level on the strategies that need to be implemented.
