Delighted to have Chris Packham opening the National Emergency Briefing. I'll be chairing as 8 experts give briefings on the lastest science and evidence.

Our leaky housing hangs round the neck of the UK economy like a lead weight, dragging households towards poverty and will do so forever or until some government or other has the courage and vision to invest in sorting it out.

I first looked into Longborgs work when I first deciding whether to work on climate stuff. His book ‘The Sceptical Environmentalist’ claimed people like me were psychologically wedded to a disaster outlook. I thought I’d better see if he had a point before pivoting my carreer…

Haha. In 2013 Duncan Clark and I wrote a whole chapter about the equation that Bill Gates invented 3 years later - the Kaya identity. It had actually been around for ages.

Maybe the issue is more the "no additional heating" stance than the use of GWP* per se? bsky.app/profile/arie...

Yep. The dazzlingly simple principle is that dishonest politicians are unfit -however enticing their narrative. Hence my book ‘A Climate Of Truth’ (which btw is about everything that matters including climate). Audience response at talks tells me very clearly there is huge hunger to raise the bar.

And to be clear SAF is emphatically NOT a ‘game changer’, requiring way too much land, to much energy or hundreds of times too much used cooking oil, depending on which type of SAF you opt for.

Fossil fuel companies also know that more and cheaper renewables will NOT be enough to stop them extracting and selling fuel at ever rising rates. They know that only a constraint directly applied will achieve that. Hence they make sure a carbon price doesn’t happen - because it could actually work!

Whereas for example Battery Smart is replacing blue smoke emitting 2 and 3 wheeler vehicles with electric + battery exchange in cities across the developing world. Fantastic for climate and air quality. Cheaper and better for users and highly investable.

Agreed. Those who do so should watch out though because when properly used, GWP* actually makes a much stronger case for methane reduction than can be seen using GWP100.

Do you think your MP is aware of the full implications of the climate crisis, across health, national security, food security and our economy? Ask them to attend the first National Emergency Briefing on 27 Nov: www.nebriefing.org

Mike Berners-Lee making the point that since COP1 there is scant evidence of a change in the rate of global emissions growth. Claims the process has been 'corrupted' by cynical actors since day one.

😱

Thank goodness. At last. I’m delighted to pay more tax in exchange for some desperately needed community and infrastructure building. www.theguardian.com/politics/202...

Catch me on @radio4rne.bsky.social at 6.30 pm tomorrow (Wed 15 Oct) talking about the climate impact of Big Tech and AI, on Carbon Lifeforms with Jon Long and Dr Tara Shine and fellow guest Chris McCausley. Thanks for having me on! www.bbc.co.uk/programmes/m...

Looking forward to kicking off Day 2 of @blueearthsummit.bsky.social on Thurs 16 Oct. I'll be on the Blue Earth stage at 9am, talking about the vital role of truth in tackling the polycrisis, and the role every business can play. Ending with audience Q&A,so bring your questions!

What a great achievement for the CarbonAccounting Alliance to convene such energy and participation at its first conference today! I was glad to have the opportunity to spell out some of the current problems and opportunities in carbon accounting ⬇️

Great crowd at the Carbon Accounting Alliance's 1st conference today! @mikebernerslee.bsky.social was on stage with Sage's Duncan Oswald, chaired by Emma Kisby, talking about #CarbonCommons - our joint project to make carbon accounting system complete: www.sw-consulting.co.uk/carbon-commons

I’ll be talking at the Carbon accounting Alliance today about the step change that this industry is so long overdue for.

This is one of the critical questions for humanity right. We have to learn how to contain persuasive and manipulative psychopaths instead of promoting the to top leadership positions.

Carbon offsets are, and always have been, a complete and utter con, designed to permit business as usual and free-market capitalism in the fast lane www.theguardian.com/environment/...

It was great to be at @thepackhub.bsky.social last week talking about innovation in packaging and the position of the packaging challenge in the context of the other big issues facing humanity in 2025. Extended Producer Responsibility is one lever to help pull packaging into a sustainable future.

Fossil fuel companies are making a packet while the world burns, writes @mikebernerslee.bsky.social. The only way to stop that is to start hitting them in the pocket www.independent.co.uk/independentp...

Any decission on this should have been informed by experts on rehabilitation and crime reduction not populism. So frustrating. I’m just back from Coppenhagan where they treat offenders with respect and there is so little crime people leave bikes unlocked www.theguardian.com/law/2025/sep...

Would more plants in our diets be a good thing for us as a nation? It would give us: 🩺 Improved health and reduced burden on the NHS. 🥕 Stronger food security by growing more fruit and veg in the UK. 🚜 More jobs and a boost to farm profits from expanding horticulture. 1/3

Trump, Farage are agents of a fossil fuel industry fighting to keep its dominance. To stop the culture wars, we must face the crisis head-on. The National Emergency Briefing on #climate & #nature will put MPs & leaders in front of the unfiltered science: risks and solutions 🌍🔥 🧵1/3

Climate Fresk workshops have proved to be a brilliant way for millions of people around the world to become informed and engaged citizens. Now the amazing and dynamic people at Future Proof Cumbria are bringing this to Kendal. www.facebook.com/100064874550... Sign up and bring freinds!

This briefing has an amazing, top line up. Even those who think they already know all the essentials of climate and nature are likely to gain transformative insights. Please press your MP to be there .

This November, 8 top experts, chaired by Prof @mikebernerslee.bsky.social will deliver an essential briefing to politicians and influential people on the climate and nature emergency—outlining threats & solutions. Has your MP confirmed yet? Enter your postcode to find out: www.nebriefing.org

Honesty in Politics 📆 11 Sept, 7 pm 📍 Brewery Arts Centre, Kendal 🎫 Book tickets: www.breweryarts.co.uk/event/mike-b... Whatever it is you care about most – immigration, inequality, Gaza, climate, Ukraine – progress depends on one thing: raising the standards of honesty in our politics. 1/3

The climate doesn't care how many renewables we have - only how little fossil fuels we burn. @mikebernerslee.bsky.social explains why making things more efficient increases the amount we use.

Honesty in Politics: Sept 11 Brewery, Kendal A non-partisan event to nail how we can raise the standard - locally and nationaly. I'll talk from my book 'A Climate of Truth'. Then 4 political parties will be represented in a panel debate with plenty of Q&A. www.breweryarts.co.uk/event/mike-b...

Gaza is establishing a wider precedent that it is ok to allow mass deaths. In that world every one of us is left hoping that no one we care too deeply about is in the next group to go. Ghastly for all of us. (And especially troublesome for those who try to care about everyone)

Every time we spend money we push for one future or another. Here are even more reasons not to buy from Amazon and a link to pledge not to do so in August - but why stick to just one month? The other 11 are also great opportunities for spending thoughtfully. bit.ly/458vs5B

Here's a compelling video from former senior foreign office diplmat @carneross on UK complicity in genocide. youtu.be/rLN7SrfTeZ4 (And a note from me for climate campaigners: A global community that allows genocides doesn't stand any hope of dealing with climate.)

Missed the launch of Carbon Commons at London Climate Action Week? Here's @mikebernerslee.bsky.social to take you through it. More ⬇️

Oh no! This is such a load of nonsense. This government needs some incredibly basic training on joined up thinking. www.theguardian.com/business/202...

This briefing beautifully sums up the argument for banning fossil fuel adverts. Parliamentary debate July 7th 4.30. Please encourage your MP to be there. Well done @victoriaharvey.bsky.social for putting this together and @chrisgpackham.bsky.social for the forward. www.mpwatch.org/fossil-fuel-...

On 7 July MPs debate a ban on fossil fuel ads and sponsorship. A tobacco ad ban in 2003 was effective. Fossil fuels will kill more people than tobacco through climate change - we need a ban now. Dr Victoria Harvey from our team has written this briefing: drive.google.com/file/d/1uede...

Looking forward to talking about A Climate of Truth in Bradford tomorrow (Sat 28th). There are still seats left. www.bradfordlitfest.co.uk/event/a-clim...

This is so well deserved! @estelledehon.bsky.social had a huge role in fending off the Cumbria Coal Mine. Just a shame she had to spend her time on this fight that would never have had to have been fought if it hadn’t been for numerous bad actors pushing that mine along with bogus arguments.

This is nuts. We shouldn’t have to be fighting needless battles like this. So annoying. Just like the coal mine farce, mad ideas like this just get in the way of sensible policy making for improving lives and dealing with climate.

Great to see our Landscape Carbon Tracker launch. We're inviting local authority teams across the UK to come and join a discussion on the merits of territorial and consumption-based emissions assessments. Join our webinar on 17 June here: www.eventbrite.co.uk/e/how-should...

Very pleased to have this chance to talk to health professionals about the importance of their sector enabling systemic change. Especially by modelling critical values: kindness to all, honesty and, of course, respect for environment.

Very happy to have been in conversation with the wonderful Rosie Boycott at the Hay Festival yesterday, talking about my book ‘ A Climate of Truth’ www.theguardian.com/books/2025/m...

I was lucky enough to be asked to review 'Consumed' by Saabira Chaudhuri, an investigation into the role that big brands have played in getting us hooked on plastics. It's published today in the UK, available in the bookstore or audio store where you choose to spend your money. 1/2

I'll be at London Climate Action Week on 24 + 25 June with the Small World team. Here's where we'll be:

Having said this one thing Andrew Bowie has shown himself permanently unfit for office. The same goes for any colleagues who don’t challenge him. The rationale for this is laid out in my book ‘A Climate of Truth’ - which, to be clear, is not party political. www.theguardian.com/politics/202...

Something's wrong when scientists have to protest outside Parliament to be heard, whilst ministers hold cosy meetings every day with lobbyists for the companies destroying our environment. #ScienceToPolitics #ScientistsForSurvival #ActOnFacts @mikebernerslee.bsky.social @chrisgpackham.bsky.social
