Text reads: Imperial Grantham Insitute – Reclaiming our Common Future: The pursuit of shared purpose in an age of division with Dr Gro Harlem Brundtland. Wednesday 29 October 2025.

Delighted to share that Dr Gro Harlem Brundland – first woman PM of Norway, former DG of the WHO, founding member of the Elders, and sustainable development pioneer – will give this year's @granthamicl.bsky.social Annual Lecture.

Join us in London on 29 October: www.imperial.ac.uk/events/19827...

Human-induced climate change drove extreme temperatures across Europe this summer. New work from @granthamicl.bsky.social and @lshtm.bsky.social reveals how thousands of people lost their lives as a result.

This from the climate minister? How grim. O’Brien either has his head in the clouds or is being intentionally misleading. Sustainable Aviation Fuels made up 0.3% of jet fuel last year; they're far too expensive and difficult to scale to play any significant role in the foreseeable future.

Historic heatwave unfolding in France.

Bordeaux just observed its hottest day on record with a provisional 41.6°C (107°F) — data since 1920. Red level extreme heat warnings are in force for the south of the country.

Sadly, this heatwave is far from over...

In a new piece for @granthamicl.bsky.social, @frediotto.bsky.social and I unpack the significance of the ICJ’s landmark advisory opinion.

We reflect on how it reshapes the legal framing of climate action and what it means for states’ obligations going forward.

Three key takeaways:
- Fossil fuel subsidies and licensing can now constitute internationally wrongful acts
- The 1.5°C limit is no longer aspirational - it's a legal obligation
- States cannot hide behind "concurrent causes" to avoid climate reparations

2/5

Good news is somewhat of a rarity in the climate space, so it's genuinely uplifting to see how advances in climate science are making it possible to hold big emitters to account in the courts.

Great new piece on @granthamicl.bsky.social's climate litigation work by @chloefarand.bsky.social 👇

Opinion | It’s Time to Name Heat Waves Like We Do Hurricanes

Excellent article by fellow sociologist @ericklinenberg.bsky.social.

"Heat is a silent and invisible killer. It usually fails to generate the kind of spectacular imagery that lands weather on prime-time television or a newspaper’s front page."

“The climate crisis isn’t tomorrow’s problem, it’s today’s, and its impacts are a broad-spectrum enshittification”.

@zoesqwilliams.bsky.social hits the nail on the head in this piece referencing the @granthamicl.bsky.social - @lshtm.bsky.social heatwave study.

If extreme weather had a capital, it would be Mumbai. We’ve got it all: floods, sea-level rise, cyclones, heat islands.

Mumbaikars are sick of being called resilient and being caught off-guard.

But forecasting the monsoon is fraught, more so with climate change. My dispatch for @carbonbrief.org👇🏽

The pursuit of 1.5°C endures as a legal and ethical imperative in a changing world As the world nears 1.5°C of global warming, near-term emissions reductions and adequate adaptation become ever more important to ensure a safe and livable planet for present and future generations

What becomes of the 1.5°C goal now that global warming is approaching that level?🌍🔥🌡️

In a new @science.org Policy Forum we explain how the 1.5°C goal remains a critical legal & ethical benchmark, even as the world nears and may soon exceed 1.5°C of global warming🧵1/

A profile image of Dr Garyfallos Konstantinoudis with overlaid text that reads: Nearly 600 heat-related deaths expected in UK heatwave. “Heatwaves are an underappreciated threat in the UK and they’re becoming more dangerous with climate change. This weekend, people need to follow heat-health advice and check on older people, particularly those living alone.” Dr Garyfallos Konstantinoudis, Grantham Institute – Climate Change and the Environment

Heatwaves are silent killers, increasing risks for vulnerable people and exacerbating existing conditions.

Rapid analysis by the Grantham Institute and @lshtm.bsky.social estimates that nearly 600 lives will be lost due to the current UK heatwave.

⚠️ Heatwaves kill and #ClimateChange is making them more deadly.

The true costs of climate disasters Scientists have linked extreme weather to climate change. Now they can quantify its impact on the damage, writes Chloé Farand.

🚨 Human influence on our climate is cranking up the intensity of #ExtremeWeather around the world.

@granthamicl.bsky.social is pioneering tools to uncover the economic and human costs of this influence on individual events.

New from @chloefarand.bsky.social 👇 www.imperial.ac.uk/Stories/true...

⚠️Global warming caused by humans is advancing at 0.27°C per decade – the highest rate since records began.

Climate warning: Ireland not prepared for extreme weather risks due to become ‘catastrophic’ Ireland is facing immediate critical risks from extreme weather events that are on course to become “catastrophic” later in the century.

A child born in Ireland today faces immediate risks requiring 'urgent action', many more that will be 'critical' by the time they're 25 & some that will be 'catastrophic' when they're a pensioner. Stark warning from National Climate Change Risk Assessment

West Nile virus detected in UK mosquitoes for first time

“Immediate risk is probably not great to humans. But as summers get warmer and longer, the boundary of WNV will shift north and we will likely start seeing endemic infections, initially in the south”

Climate change is driving an increase in spring temperatures across the UK and this spring has been the driest in at least a century.

While many of us have enjoyed the conditions, they create enormous challenges for the people who produce our food. 👇

We should probably do something about that…

Why ‘de-extinct’ dire wolves are a Trojan horse to hide humanity’s destruction of nature Extinction is, for the time being, forever – and a symptom of our global economic system.

“It’s like claiming to have brought Napoleon back from the dead by asking a short French man to wear his hat.”

A short piece in The Conversation by me on why “de-extinction” is nothing of the sort, and bad, bad conservation.

A man and woman cycle side-by-side on blue and yellow shared bikes along a red asphalt protected bike lane outside Utrecht Centraal Station.

Why do Dutch railways invest in shared bikes?

54% of users ride the train more often because of its availability. Without OV-fiets, 8% would use a car instead of the train.

Every euro returns up to €2,40 in societal benefits, with improved accessibility, congestion, and health and safety outcomes.
