On the 17 September, a JOC (CEE) heard testimony on Temperature Neutrality (TN).

We made a submission otlining the risks of adopting TN and calling for the release of the Land Use Review 2 report.

Well done @thinkorswim.bsky.social.

This is a bloody great read, had to pick my jaw up off the floor a few times!

If you ever write an autobiography, I will definitely read it.

‘She is ignorant of how ignorant she is’: JK Rowling responds to Emma Watson rift The author has rebuffed conciliatory remarks made by the Harry Potter actor, saying Watson has ‘enthusiastically participated’ in the ‘trashing of women’s rights’

Words do indeed matter.

It's just a shame that Rowling only seems to recognise the injury other people's words do to her, without ever sparing a thought for the damage she has done to the rights, dignity and safety of many others.

Israeli politicians react bitterly to international recognitions of Palestinian state Experts say move by nations including UK and Australia won’t change government policy and could strengthen its grip on power

Giving Hamas a prize?

I can assure you, this is not about prizes, and they certainly do not hand out prizes for the starvation of women and children.

If you would rather see people starve than recognise their right to self determination, then you are broken.

God in a Box I’ve been thinking about AI for some time now, and I’ve been experimenting with it in my daily workflow. It is undoubtedly powerful. It has…

Are you living with AI Creep?

It is an important part of my workflow, its a notepad, a tutor, and a sounding board, for me at least.

It is reshaping everything from the classroom to our mental health in suprising, and sometimes terrifying ways.

Here is my take.

'Our Genocide': How do Israelis feel about the war in Gaza? – video Reporter Matthew Cassel speaks to Israelis in Tel Aviv, to see what they think of the war, famine and genocide happening next door, and the growing international condemnation against it

Pretty rough viewing at times.

I am staggered by the levels of hypocrisy and self-delusion.

I don't know how you reason with it when the conclusions reached are so unreasonable.

John, whatever credibility and integrity you had was gone a while back.

Good luck to you, I hope you can find a better way of communicating with people.

It would seem to be part of your job.

John, you're calling for their heads and me a "dope".

I do want to engage with the issue, but not on those terms.

I don't doubt you have a credible argument.

I am just not inclined to listen to people who call me names or take extreme positions.

You're calling it malpractice. You are literally screaming hysterically rather than contributing to a debate.

Calling me names does not increase your credibility.

I am interested in both side of the argument.

Just not in being called names by a "journalist"

Grow up John.

Firstly, that's your subjective opinion. It's a podcast, not a courtroom.

Secondly, my main issue is not with your premise, it's your rage-baiting that I have an issue with.

There is enough toxicity everywhere you look.

Be better.

Malpractice? ... Tone it down a bit.

You can respectfully disagree. It's not like the world needs more polarised view points.

If you are going to contribute to a debate, then make a constructive contribution.

Stoking outrage is cheap.

I share concerns around tools that, misused, reduce engagement and broader understanding that you get from reading around topics.

But, perhaps there is a way to maximise the benefits and minimise the trade-offs.

There are some different takes in this podcast

Not a lot I disagree with in John's big picture view.

This looks pretty interesting 🤔

Best I can tell, it's also free.

Through the Lens Systems Thinking No Additional Warming and Systems Traps

🪤 Its a trap!?

Does “no additional warming” reinforce systems traps?

I take our recent paper on temperature neutrality and put it through a #SystemsThinking lens — looking at how it reinforces the very traps we need to escape.

There is nothing defensible about the cruelty being inflicted on, and the engineered starvation of, people of Gaza.

I can’t do much, but, like many other scholars, I have signed the Academics for Palestine pledge.

Collapse of critical Atlantic current is no longer low-likelihood, study finds Scientists say ‘shocking’ discovery shows rapid cuts in carbon emissions are needed to avoid catastrophic fallout

As if we needed another reminder that we are moving too slowly in terms of climate action.

The ability for us to alter this truly scary future is in our hands .... But not for long.

France summons US ambassador Charles Kushner over antisemitism allegations Kushner says in letter to Macron he’s concerned over ‘rise of antisemitism’ and ‘lack of sufficient action’ to confront it

Living in the "post truth" era is pretty distressing.

I have as much faith in statement from the US and Israel as I do from Russia.

The truth is, Israel is intentionally starving an entire population. It is in no way antisemitic to point that out.

www.theguardian.com/world/2025/a...

Sorry to disappoint anyone trying to polarise this.

We’re with farmers and communities, for a just transition built on fair, predictable policy.

“No additional warming” is a moving target and inequitable.

Set clear, stable, just targets to support a just transition.

Row over 'temperature neutrality' vs 'climate neutrality' A big academic row has broken out among Ireland's climate scientists over the commitment to a "climate neutral economy" in the country's national climate objective, writes George Lee.

Disappointed to see our new paper being framed as an "us against them" fight.

We are contributing our work to the debate on Ireland's future in a respectful, evidenced based way.

There should be no issue with doing so.
