This is the most important thing you will read today – and probably the whole year, honestly.
We cannot let the AMOC collapse. For one thing it will make Iceland uninhabitable, and I would really like my children and grandchildren not to become refugees. But the effects will be almost everywhere.

It's the opposite of his intention, but the Idiot Emperor is forcing the world off fossil fuels. This week's column.

"Just as we make ourselves more energy-secure by switching from fossil fuels to renewables, we make ourselves more food-secure by switching from animals to plants." - @georgemonbiot.bsky.social
With Prime Minister Carney having secured his coveted majority, and a federal election likely three years away, now may seem an odd time to issue this appeal. But I beg to differ:
Here's my call to climate justice champions — run! — for office... 😊 👇 www.nationalobserver.com/2026/04/14/o...
just a note: while Quebec does not have UBI, they do have universal health care, which is a floor of sorts that probably helped create AdP.
"a world with universal basic income is more meritocratic than a world without one, because luck-based distribution — which is what we have now — throws away most of the talent in the room."
The clearest evidence that the increase in atmospheric CO₂ is due to humans is in carbon isotopes. Fossil fuels have no ¹⁴C and are depleted in ¹³C. As we burn them, the ratio of ¹⁴C and ¹³C relative to ¹²C in the atmosphere drops (look up the Suess Effect).
Claims and ideas which happen to favour the ruling class don't dominate public life by accident. They're paid for by oligarchs and corporations then promoted by media outlets other oligarchs and corporations own. Once they've been drummed into our ears enough, they're internalised as "common sense".
Critical Atlantic current significantly more likely to collapse than thought
- Scientists say finding is ‘very concerning’ as collapse would be catastrophic for Europe, Africa and the Americas

The #AMOC by 2100 will thus be so weak (~8 Sv) that it is very likely on the way to full shutdown, as our study last year showed: iopscience.iop.org/article/10.1...
In my view, this now makes a full #AMOC shutdown more likely than not. Definitely not a low likelihood risk, as we used to think.
“I now am increasingly worried that we may well pass that Amoc shutdown tipping point, where it becomes inevitable, in the middle of this century, which is quite close.”

Really enjoyed this detailed autopsy by Simon Copland of the “Abundance” book: “Abundance Gets It Wrong”
greenagenda.org.au/2025/09/abun...
"In one scenario at CO₂ concentrations of 450ppm —last experienced by Earth several million years ago, when polar ice was significantly reduced—Antarctic temperatures rise by 6°C while Arctic temperatures drop by 7°C due to #AMOC collapse"
We're now at ~430ppm & rising 🙈

'Fewer than 60,000 people – 0.001% of the world’s population – control three times as much wealth as the entire bottom half of humanity, according to a report that argues global inequality has reached such extremes that urgent action has become essential'

Climate denial and anti-vaccination are not popular ideas. Substack is actively and forcefully promoting these people and their views for blatantly ideological reasons
A Japanese researcher just interrupted me in the restroom and said, “are you David Ho?” He proceeded to tell me how much he enjoyed this piece I wrote in Nature. You should read it too. 😄
I don't know why this is so hard for some people to grasp. If we extend our use of fossil gas, rather than going all-out for grid batteries, heat pumps and induction hobs, we extend our dependence on *foreign* sources of gas, regardless of whether we also use the UK's last remaining reserves. 🧵
And, of course, fossil energy and climate change are both affordability issues — which means you can’t solve for affordability (or even set expectations) without taking on fossil energy and climate change.
Trends in Concern About Global Warming or Climate Change, by Political Party I'm going to read you a list of environmental problems. As I read each one, please tell me if you personally worry about this problem a great deal, a fair amount, only a little or not at all. How much do you personally worry about global warming or climate change? % Worry a great deal - Democrats - 72%- Independents 46% - Republicans 6% 80% 72 70 60 50 • 46 40 30 20 10 2002 2010 2018 2026
Americans DO care about #ClimateChange!
Don’t listen to the partisans who lie about this.
72% of Democrats & 46% of independents “worry a great deal” about climate.
And 68% of Democrats & 47% of Independents expect global heating to threaten their way of life NOW or in the future.
Interesting. An international conference specifically about transitioning away from fossil fuels. This is a way for countries that get it to cooperate outside the sclerotic UNFCCC framework. Worth watching.
I’m going to block this AI bot doing PR for CDR, but first I will say that the majority of CDR in mitigation pathways is there so models can show us hitting our targets while burning fossil fuels at massive scales.
And this vision is justified only by technooptimism and unicorn farts.

Such an important topic: new study shows feeling fearful appears to motivate people and is linked with greater support for #climate policies, while dread is associated with lower support

Something is starting to shift.
Millions of people are waking up to what the fossil fuel lobby has spent decades trying to hide: clean energy is cheaper, safer and doesn't need a single bomb dropped to keep the lights on.

You, an individual, cannot "fix" the whole world. You can act at the scale of your life. You should act at the scale of your life.
I've excerpted a ~5 minute segment from my recent livestream discussing my deepening concerns regarding on the ongoing (and accelerating) threats not only to weather and climate science, but American science leadership and continuity at large.
Wildlife trade drives animal-to-human pathogen transmission over 40 years
New in @science.org ‼️ In the most comprehensive study to date, we show that wildlife trade is driving animal-to-human zoonotic spillover at a planetary scale, with +1 spillover per host every 10 years. Live animal markets and illegal trade pose even greater risks. 🔓 www.science.org/doi/10.1126/...
Canada may spend billions on LNG projects that will lock us into higher prices and delay real climate solutions.
Apr 13-18 people across the country are speaking up:
❌ No more public $ for fossil fuel giants
✅ Invest in clean energy that benefits communities
