A little reminder of science history: air temperature change after a shutdown of the Atlantic overturning circulation #AMOC, as simulated in climate models 36 years apart.
Suki Manabe went on to win the physics Nobel prize in 2021 jointly with his colleagues Klaus Hasselmann and Giorgio Parisi.

collaborative proposal writing tip:
start the narrative out with one font size larger than the minimum allowed. Then in the final days when everyone is squeezed for space, drop down to the proper font size. This forces everyone to write more concisely from the start.

COP - A HISTORY OF BETRAYED PROMISES

COP30 started last week: while the stakes keep getting higher, the inadequacy of this assembly is getting painfully more evident year after year. (1/5)

A starfield is shown above a mountain peak. Just above the mountain and extending up toward the upper right is a blue-tinted tail of a comet. The comet's head is just to the left of the peak. Please see the explanation for more detailed information.

He is not wrong. The best I could do while head of school was the prophylactic offering of trying to protect my staff from the worst of it, to preserve a bubble of academic environment.

Love to see community action against this AI nonsense! neighborhoodview.org/2025/11/13/d...
As one Massachusetts school administrator recently said; this moment with AI is remarkably like the moment when we were introduced to asbestos. Yes, it had some remarkably promising characteristics – fireproofing! – and had some real utility in science, research, and industrial applications. But a profit-driven industry bullied us into inserting it everywhere; into our homes and schools and public spaces, before we really understood the risks. This resulted in decades, if not centuries, of illness, injuries, deaths, and the astronomical financial burden of trying to remove the stuff. As you, the leaders and policymakers in our schools, craft an AI policy for our district, we the undersigned call on you to: 1. Ban AI tools into the classroom, protect our students and teachers from de-skilling and allow them the space and time to engage in assignments themselves. 2. Resist any direct financial relationship or contracts with AI providers, as well as the “training” they might offer. 3. Provide a digital literacy curriculum to help students navigate the current digital landscape, and promote critical engagement with technology. 4. Guarantee that anywhere generative AI has already entered our classrooms or curriculum, an opt-out will allow students and teachers to refuse the use of these products at no risk to their grades, progress or employment.

The irony here is that academics don’t just write the articles for free—we also referee and edit for them for free. Something is deeply broken.

“New Zealand's eight universities spent $30-million a year on journal licences and about half of that sum went to Elsevier.

I've loved seeing the joy that the end of the Monash Woodside partnership has brought people.

Criticizing fossil fuel sponsorship can feel lonely, but it turns out, lots of people want their education & workplace free from climate criminals.

We can have nice things without them.

Climate breakdown is driven by a storm of lies. This lying is systemic, funded and coordinated, and operates across almost all media, old and new.
This week's column argues that we cannot fight the climate crisis without also fighting the epistemic crisis.

The Woodside Monash Partnership is over...there's some concern this may be permuted into a situationship through continued Woodside funding of research BUT overall a strong message that taking fossil fuel funding is NOT aligned with sustainability.

📣 For the first time ever, scientists have confirmed seeing a giant explosion on a star other than our own!

Our XMM-Newton observatory and the LOFAR telescope contributed to making this long sought-after discovery 👉 www.esa.int/Science_Expl...

🔭 🧪 ☄️ ☀️ 1/
An artist’s impression of a large red star releasing a bright, explosive burst of light. Swirling red and orange patterns surround the star, suggesting intense activity. In the background, a smaller blue planet appears with a faint, wispy trail extending away from it, indicating its atmosphere being blown off. The scene is set against a dark space backdrop dotted with stars.

For taxpayers, every piece of cycling infrastructure is a gift that keeps on giving.

An asset that returns annual savings in congestion, pollution, maintenance, safety and healthcare over its lifetime.

Stop asking whether your city can afford to invest in cycling. Ask whether it can afford not to.
