The underwater forests fighting climate change

“Imagine you’re trying to grow a rainforest, but the trees grow about a foot a day,” says Zhenna Azimrayat-Andrews, a PhD student at the University of Cambridge. “You could really store a lot of carbon quickly because of just how fast the biomass grows.”

We're going to UArctic Congress

We're going to UArctic Congress 2026! With a wonderful panel, we'll be discussing what it means to build AND share knowledge of climate interventions - because we're so much better together.

A multiplicity of tomorrows: how people imagine the future with climate interventions

From 'giving the world cancer' to 'colonizing space', a new paper explores 299 imagined futures where climate interventions, like solar radiation modification (SRM) and carbon dioxide removal (CDR), reshape our world.

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.

Discover Climate Repair: seminars this Autumn

Join us this Autumn to discover more about climate repair. Hear from scientists working to understand the potential of ideas to cool the planet and stave off the worst effects of climate change.

Engineering the Planet on BBC Radio 4

Can we design and build our way out of climate change? That’s the question BBC Rare Earth asked our researchers in an episode on “Engineering the Planet”.

Jacob Pantling, a PhD student at the Centre for Climate Repair, invited to the hosts to see some of his latest experiments. Recording in the “Cold Room” at DAMTP, he explained the work being done at the University of Cambridge to support research in the Arctic.

Back in the studio, Shaun Fitzgerald, director of the Centre for Climate Repair, joined the panel to discuss where these technologies fit in our climate response.

From taboo to testing: why SAI can't be sidelined forever

In an article with ClimateGenn, Hunt sets out where we are and why it warrants thoughtful, responsible investigation of methods like Stratospheric Aerosol Injection.

Arctic Repair 2025

"This is my home, our home. The Arctic is an amazing place that needs a lot of help right now." Those are the words of Brandon Langan, a resident of the high Arctic. Speaking on the first morning of Arctic Repair 2025, he set the scene for a groundbreaking conference on potential solutions for a warming world.

Fluid mechanics for the climate

At the University of Cambridge, we’re investigating how aerosol particles could cool the planet. It’s an exciting mix of chemical engineering, mechanics, and physics in a rapidly growing field, and it could have world-changing applications. Could you join our team?

Political ideology and geoengineering: new paper

Why communicate about solar geoengineering?

While he was on stage at #ArcticRepair2025, Ramit Debnath (researcher at the Centre for Climate Repair) published a new paper on public attitudes towards solar geoengineering (SG). Through their surveys, the authors (led by Beatrice Magistro) found that more familiarity with geoengineering lessened the influence of political ideology.

As a result, they said, “increasing public awareness of SG could foster bipartisan engagement with climate policy, helping bridge the ideological divide.”
