2026 is on track to be the warmest (~35% chance) or second warmest (~63%) year on record, while 2027 is very likely (92% chance) to be the warmest on record on the back of a growing super El Niño event. For more, check out my new Carbon Brief State of the Climate Q2 update: www.carbonbrief.org/...

Under a Binface government, anyone who doesn’t accept human-made climate change as fact will be sent back to school, from Year 1 right the way to A Levels, to see if anything goes in the second time round. #VoteBinface

Despite all the noise today I'd really like you to read this, as I think it's crucial. The government's in the process of p*ssing up to £264 billion into the ground, at the behest of the fossil fuel industry. Yes, £264 *billion*. It's utterly mad, and has to stop. www.theguardian.com/commentisfre...

The great carbon capture con: behold the wasted billions Burnham could claw back | George Monbiot

There are far better ways to tackle climate breakdown, but successive governments have chosen to listen to the fossil fuel companies instead, says Guardian columnist George Monbiot

BREAKING: in June 2026, *every single one* of the 1,062 refugees admitted in the U.S. were white South Africans. In FY 2026, the U.S. has admitted a total of 7,727 white South Africans, three Afghans (back in November), and nobody else. For reference, the U.S. admitted 100,060 refugees in 2024.

Air conditioning has become the latest front in the energy culture war. Depending on who you ask, it is either wasteful excess we must resist or the only sensible response and anyone urging caution is a zealot. A few thoughts in this 🧵

Just one possible outcome... but the GFS weather forecast model is suggesting 40-41°C is possible in the UK around 7th July. This is a long-range forecast with significant uncertainty, but the fact that we are even seeing such values fairly regularly in the forecasts is extraordinary.

They gave US zinester Elizabeth Soto *50 fucking years* in prison for publishing a zine that supports an anti-fascism stance. Prosecutors also used her feminism themed zine, and an anti-AI zine as evidence against her. This is unprecedented.

I have to say, it's making me feel a little insane hearing commentators say Ed Miliband shouldn't be chancellor because of his "ideological zeal" for Net Zero, in a week where temperatures are so extreme that my kids are being sent home early every day and it's regularly 30 degrees inside my house

Grim timing yesterday as news of the Met Office Red alert flashed up on phones right in the middle of a big event about new Met Office forecasts for June 2056, showing potential peak temperatures of 45C in England. Stopping the CO2 emissions driving this is essential, but we also need to prepare.

Reform have now lost six by-elections in a row in England, Scotland and Wales. Their national poll rating is 26% – below Labour in 1983 – and Farage’s approval rating is -37. They’re very far from the voice of the people and need to stop being treated as such.

'The bathing ponds at Hampstead Heath in north-west London will remain trans-inclusive after a public consultation overwhelmingly favoured its existing rules.' Good news. 86% of 38,000 respondents in favour of retaining trans-inclusive policies.

Policy agreement means trans people will continue to have access to Kenwood Ladies’ and Highgate Men’s ponds in north-west London

When it comes to heatwaves, there is no ‘new normal’. Forget the idea of continuity. Forget journalism’s biggest psychological challenge: its inherent status-quo bias from which it looks for the newsworthy deviations. Leadership in this new human experience is the ability to embrace discontinuity.

I've got to say that I'm really disappointed in the recent discourse surrounding the RCP8.5 scenario. The lack of context and understanding is something I expected from the usual suspects, but it's frustrating to see such bad takes from people and outlets who should know better.
