It was a great event and I'm looking forward to seeing new exciting collaborations, research and ideas for solutions resulting from this research retreat. Many thanks to all contributors #AI #ClimateChange #SocioEcologicalSystems

The Pareto effect in tipping social networks: from minority to majority Abstract. How do social networks tip? A popular theory is that a small minority can trigger population-wide social change. This aligns with the Pareto principle, a semi-quantitative law which suggests...

Me and some others managed to finally publish a (long) review on social tipping, when it might occur, and what that means from a network science perspective:

So excited to learn from so many wonderful contributors. A co-produced policy brief will summarise the man insights and recommendations.

Want to know how fossil fuel companies use carbon offsets to claim they’re fighting climate change?

We've updated OffsetsDB — our offsets database — to allow you to search by carbon credit user. Search "Shell" and see what offsets they're using and when. (1/4) carbonplan.org/research/off...

Factcheck: Why expensive gas – not net-zero – is keeping UK electricity prices so high - Carbon Brief The UK’s high electricity prices have become intensely political, with competing claims over the cause of rocketing bills and how best to get them down.

Fact check: it's natural gas, not renewables, keeping electricity prices high in the UK.

Defending Human Rights Is Dangerous. Defending Nature Makes It Even Riskier - Inside Climate News Over the past decade, there have been more than 6,400 attacks on human rights defenders, with three-fourths carried out against environmental defenders.

Important reminder from @katiesurma.bsky.social that environmental defenders face violence or the threat of, sanctioned & otherwise, so often. Long neglected focus of #environmentalsecurity work. Our IR & conflict studies biases blinded us to these key dynamics. insideclimatenews.org/news/2005202...

Exploring pathways for world development within planetary boundaries Nature - Current trends imply that we will transgress most of the planetary boundaries by 2050; however, ambitious, urgent and universal action to ameliorate climate change and increase resource...

With current trends and policies, we'll transgress all planetary boundaries in 2050, except for ozone depletion. Targeted interventions — e.g., the Paris Agreement — can help, but not enough. More effective policy measures are needed to ensure we live well within the planetary boundaries.

I've watched it yesterday with my 7-year old son, it's heartbreaking (seeing what bottom trawling does, industrial-scale harvesting of krill in the Antarctica!) but also a powerful call for action. I hope the message of the movie will reach the UN Ocean Conference ocean-climate.org/en/unoc2025/

Scientists just found a way to break through climate apathy In a field of muddy results, it's among the clearest findings that one cognitive scientist has seen in his career.

Scientists just found a way to break through climate apathy #Climate

Why Protests Should Be Promises Modern movements that aim to advance racial equity should withhold and promise, rather than perform, writes Olúfẹ́mi Táíwò

"...for protests to succeed, they must be backed by movements with the ability to promise to withhold—labor, debt payments, rent payments, or consumer support—and to follow through if demands aren’t met."

Our findings suggest that scientists can engage in public protest without compromising their credibility, but that such actions alone may have less impact than one would like to believe: royalsocietypublishing.org/doi/10.1098/...

I've never seen such a crass climate change signal. A heatwave up to 10C hotter because of our burning of fossil fuels hit Central Asia last month. And this is only now, with just under 1.5C global warming. www.worldweatherattribution.org/extraordinar...
