A new report by Prof James Hansen sheds light on the uncertainties of global climate predictions - and why that means we need to respond now.

Hansen - a scientist known for sounding the alarm on climate breakdown to a UN congressional committee in 1988 - writes alongside seventeen other authors, including members of youth initiatives such as Operaatio Arktis and Green Africa Youth Organization.

They suggest that the best estimates of the UN IPCC understate climate sensitivity and that we do not yet understand the potential scenarios. In light of these uncertainties, Hansen et al advise that young people should not be prevented from having "knowledge of the potential and limitations of purposeful global cooling” – that is, climate intervention methods – “in their toolbox".

Dr Shaun Fitzgerald, director of the Centre for Climate Repair, shares his key takeaways from the report.

A new paper by researchers at the University of Cambridge details experiments into the flow of water over ice - important research for the viability of techniques to "refreeze" the Arctic. Developing on previous work by the Centre for Climate Repair, the researchers - Jacob Pantling, Grae Worster, and Shaun Fitzgerald - found experimental results from the “cold lab” in DAMTP matched the large-scale models underpinning the big ideas of sea ice thickening.

What do clouds have to do with the climate? Well, a lot! Join us on Thursday 13th February to hear from three engineers looking to the skies as they seek to protect the planet.

Engineering has changed the world. But global temperatures are rising due to human action and emissions reduction is not sufficient to protect vulnerable people and places from the worst effects of climate change. What if engineering could help cool the planet?

Arctic sea ice is key to global climate stability, but it is melting rapidly in the face of climate change.

What if we could make more sea ice? That’s one of the big questions Jacob Pantling, PhD researcher at the Centre for Climate Repair with the Department of Engineering at Cambridge University, and the team at Real Ice are seeking to answer in Cambridge Bay this month.

The Centre for Climate Repair is expanding and we are looking for an experienced Programme Administrator to join our mission-driven team. Applications close on Sunday 26th January 2025.

At Centre for Climate Repair, we're not just interested in research. In 2024, we got conversations started.

Zhenna Azimrayat-Andrews, PhD student at Centre for Climate Repair, shares her experience in Santa Barbara, California, collecting data on the carbon dioxide removal potential of kelp farms.

With COP29 now behind us, we are beginning to reflect on all that was heard and spoke about during the 2 weeks of climate negotiations that happen every year. During the first week of COP29, Centre Director, Dr Shaun Fitzgerald was in Baku speaking at various events and being involved with the discussions on the ground. In Week 2, Deputy Director, Hugh Hunt, met and interviewed various people to get their views. Here is a summary of what the Centre got up to in Baku.

"We are now well beyond the point of being able to rely on emissions reduction alone to keep temperatures below 2 degrees". Centre Director, Shaun Fitzgerald, reflects back on his time at #COP29 and the discussions being had this year including his thoughts on countries that are looking to natural gas as a sustainable solution.
