As the planet edges closer to a climate change tipping point, UK policymakers need bold solutions to prevent catastrophe. And while work to transition to net zero remains essential, some argue it’s time to turn to radical climate repair to buy much-needed time: from removing CO2 from the atmosphere to solar geoengineering to deflect the sun’s rays.

In his Minister for the Future piece, Professor Sir David King, founder of the Centre for Climate Repair, chair of the Climate Crisis Advisory Group and former Chief Scientific Advisor to the UK Government urges us to consider a unique climate repair technique: refreezing the arctic through temperature stabilisation technology.

He joined us live in conversation on 31 October 18:00-20:00 with Alan Rusbridger, Editor of Prospect Magazine, to dive deeper into the role of geoengineering technology in the fight against climate change. Alongside an expert panel from the world of climate science, we explored the technologies on the table, the controversies of using climate repair and how far geoengineering can really be used as an effective part of our toolkit.
