So you think there's hope? In the news this weekend

"So you think there's hope?" That's what someone asked us today at Cambridge Zero's Climate & Nature Research Showcase. On one of the hottest days ever recorded in the UK in June, we were presenting ideas - totally new to some attendees - that could slow or even reverse the impacts of climate change. It felt more poignant than ever. Also, climate repair featured in The Times.

Panel discussion on Climate Interventions: a distraction or a necessity?

Relative risks and fuller strategies: should we research geoengineering?

At the Centre for Climate Repair, our mission is to research potential climate actions so that society might be equipped to make informed decisions for the way forward. "Net zero remains the non-negotiable foundation," said our director in a recent article, "but the scale and pace of change now demand a fuller strategy."

"At CCR, that strategy is the “Three Rs”: Reduce emissions, Remove atmospheric carbon and Refreeze the Arctic. Each is essential; none is sufficient on its own."

Shaun Fitzgerald is director of the Centre for Climate Repair at the University of Cambridge and Hugh Hunt is deputy director. They were approached by various news outlets in response to a new paper assessing some the Centre’s research themes; here’s some of what they had to say.
