I'll be at the Beth Chatto symposium next month, on a panel discussing how gardening and food production can continue under a changing climate! www.bethchatto.co.uk/symposium/sy...

1/ Predictions of future climate improve over time, but this shouldn't weaken the Paris Agreement. But in several widespread interpretations of "well below 2C", it does. New (short!) paper with @joerirogelj proposes a fix. www.nature.com/articles/s41... 🧵

Future-proofing interpretations of the Paris Agreement’s limit of well below 2 °C - Nature Climate Change

Here the authors show that a common interpretation of the Paris Agreement’s ‘well below 2° C’ target is changing with time, which could lead to higher overall warming. They propose that using median t...

Future-proofing Paris Agreement requires focus on median warming In a new paper, Prof @joerirogelj.bsky.social & Dr @robinlamboll.bsky.social warn that global warming closer to 2°C is at risk if countries don't use median temperature targets to guide reductions in emissions 🧵 buff.ly/pbNssJf

I'll be doing a half hour of science poetry at Morden Family Fun Day in the Poet's corner from 3pm - come along if you're nearby! www.mertoncharityevents.org.uk/morden-famil...

Professor @joerirogelj.bsky.social and Dr @robinlamboll.bsky.social have contributed to the latest Indicators of Global Climate Change (IGCC) assessment, showing human-induced warming reached 1.37°C in 2025. At current emissions trends, 1.5°C could be exceeded within around four years.

After YEARS of climate scientists using '1% CO2 growth per year' to calculate atmospheric constants to TERRIFY us, the UN's TOP climate scientist (Detlef Van Vuuren) just admitted that scenario was WRONG! WRONG! WRONG! I hope henceforth we will calculate TCR using TRUTH, SCIENCE and SSP2-4.5!

Every word of this paper on how a sea lion can beat humans at dancing is a gem, but best of all is the general tone that it was written by a proud sea lion's mum using science words to describe a rave. www.nature.com/articles/s41...

Strong legal ruling from the Dutch courts, obliging the government to strength climate targets and provide climate resilience for the residents of Bonaire! www.rechtspraak.nl/organisatie-...

This is absolutely HUGE news – a court in the Hague has ruled that the Dutch government is failing the people of Bonaire, and must set up a climate adaptation plan for them AND raise its climate targets Major victory for #ClimateJustice, and for the people of Bonaire

Just a few quotes from the Declaration of Independence

I wish little chocolates didn't come individually wrapped. (Not for environmental reasons, just to make it harder to see how many I've eaten.)

If Ireland's emissions are "too small to matter" then I might as well evade my taxes and eat doughnuts for lunch. Read my latest column about the laziest excuse in the climate debate: www.irishtimes.com/environment/...

‘Too small to matter’ is the laziest-possible excuse in climate debate

At a time of crisis, co-operation is the only way to resolve the climate collective-action problem

This COP has been deeply disappointing. It claimed to be a COP of action, but all comments on fossil fuels, and even most comments on deforestation that this COP was supposed to highlight, have been removed from the final text. Being literally on fire at one point was a fitting metaphor.

Kenya have got their text into the loss and damages agreement and it looks unanimous now, so there will be an agreement coming out of COP!

On Wednesday, I'll be on a panel about climate justice at COP30 in Belem. We'll be talking about indigenous rights, community judgement of COPs and what climate justice looks like - I'll be more on the metrics and less on the social side of these questions!

I'll be presenting on including AI effects in energy models at IAMC this Wednesday. Then next Wednesday I'll be in Belém to give a short talk as part of an event on COPs, indigenous activism and climate justice in the Blue Zone GUAC pavilion at 10.30. If you are around, catch me for a chat!

Do climate conferences actually achieve anything? A lot of people have strong opinions, but we wanted measurements, so we look at how the stock market moves during yearly international meetings called COPs – explanation below, or read the paper here: iopscience.iop.org/article/10.1...

📈COP delivers stock market boost for ‘green’ companies but renewables unaffected, Imperial College London study shows 🧵 Read it here: ow.ly/o6xY50XnEuH

Something that's worth flagging about this report is the subtle pivot from "current policy" being the worst-case scenario to including discussions of backsliding. Most calculations presented include the USA meeting its new-but-Biden-era NDC commitments, which will formally elapse in Jan.

NEW: The latest climate pledges under the Paris Agreement have driven only a slight fall in predicted global temperature rise over the course of this century. The UN Emissions Gap Report finds that implementing current policies would lead to up to 2.8°C of warming, down from 3.1°C. 🧵

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope. According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

There's an informative paper by Bossy et al out today, probing the emissions pathways compatible with keeping earth within five different planetary boundaries: www.nature.com/articles/s41... I wrote a little context-setting piece about it, which you can find here: www.nature.com/articles/s41...
