Gabrielle Walker Biography

Dr. Gabrielle Walker is a leading voice on climate change and carbon removals globally. A founder of Rethinking Removals and CUR8, she works with the most impactful global actors to accelerate the development of the carbon removals industry. She is a TED Speaker, and a Global Ambassador for Client Earth. She is an author, expert strategist and moderator—with a focus on sustainability, new energy and climate change. She has decades of experience working at C-suite and Board level to challenge conventional thinking and turn innovative ideas into action.

Walker gives keynote addresses to corporate audiences around the world and has moderated panels involving global CEOs, former heads of state, government ministers, military generals and global humanitarian leaders. She also designs and facilitates innovative “safe-space” conversations between global leaders, from small round tables through to major international meetings.

Walker has presented many TV and radio programs for the BBC. She has been Climate Change Editor at Nature 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 the bestselling "The Hot Topic, how to avoid global warming while still keeping the lights on", 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,” Walker 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.
