A reality check for me was working with students on an internal carbon accounting platform that Bon App our food provider uses. Beef was less than 5% of our purchases but around 50% of our food emissions even with international work to be plant forward.

A recipe for avoiding 15 million deaths a year and climate disaster is fixing food, scientists say

Scientists are presenting new evidence that the worst effects of climate change can’t be avoided without a major transformation of food systems.

Damn. This is amazing. £325 per week, paid monthly, for 3 years - and the result was a profit for the Irish economy:

Post from Threads user rodneyowl: "Ireland has declared the Basic Income for Artists scheme permanent. This will be officially announced in tomorrow’s budget. Details to follow. Congratulations to all who fought for it and the present and future artists of all sorts in Ireland. That includes me 👌We’re just comin to the end of a 3 year pilot scheme. It’s been a roaring success. For every €1 paid out to the 2000 participants, the government got €1.46 back. Can’t argue with that. Other countries are already taking note."

The real headline is there in the article:

“The wealthiest are increasing their wealth faster than any other group.”

That’s the story. Not the meaningless number.

Richard Davy @davyclimate.bsky.social · 4d

So when we say the richest 1% hold $52 trillion, we just check out. It sounds like monopoly money.
We’re not wired to understand exponential scales — and that’s exactly how the story slips past us.

Richard Davy @davyclimate.bsky.social · 4d

Who has a sense of what $52 trillion means?
It’s too big, too abstract. Even billion vs. million is a scale most people can’t intuitively grasp — a billion seconds is 31 years; a million seconds is 12 days.

Richard Davy @davyclimate.bsky.social · 4d

Growing wealth inequality is devastating for societies.

But with headlines like “the wealth of the top 1% reached $52 trillion”, the topic gets ignored — because those numbers mean absolutely nothing to anyone.

wealth of the top 1% reached a record $52 trillion (icymi friday) — www.cnbc.com/2025/10/03/t...

The wealth of the top 1% reaches a record $52 trillion

All wealth groups saw gains over the past year, according to recent Fed data. But the growth has been fastest for those at the very top.

I am happy to announce that we received major funding from Schmidt Sciences under their VICC program to study rapid #Permafrost Thaw Carbon Trajectories (PeTCaT). The 5-year project led by my team @awi.de partners with an international team to quantify how rapid thaw contributes to climate change.

Schmidt Sciences @schmidtsciences.bsky.social · 7d

We're investing $45M over 5 years to launch the Virtual Institute for the Carbon Cycle (VICC).

Four global teams will combine AI, advanced observations & modeling to close major carbon cycle gaps, strengthening climate projections worldwide.

By applying a tracking method to both climate models and satellite data, @davyclimate.bsky.social found that sea ice age is a more sensitive indicator of change than ice thickness or volume.

I may have found my defining quote.

Pair this with my pinned post and you will see what I mean!

From a poster called “just shower thoughts“ reading: when people talk about traveling to the past, they worry about radically, changing the present by doing something small, barely anyone in the present to really thinks that they can radically change the future by doing something small.

Thanks to the fantastic team at NERSC, Jakob Dörr, and Philipp Griewank.
If you’re working on climate dynamics, prediction, or sea ice processes, I’d love to hear your thoughts on how sea ice age could play a role in your work.

This work also launches us into our new ESA project, SAGE, where we’ll dig deeper into how sea ice age can reshape the way we evaluate and improve climate models. Stay tuned. 🌍❄️

Richard Davy @davyclimate.bsky.social · 16d

Most exciting: sea ice age reveals low-frequency variability in the Arctic (see Fig. 5 in our paper). This opens a new window into decadal-scale fluctuations — crucial for improving #ClimatePrediction systems.

Richard Davy @davyclimate.bsky.social · 16d

For the first time, we applied the same ice-tracking algorithm to both model output & satellite observations. This fair, like-for-like comparison reduces long-standing biases and shows that sea ice age captures dynamics thickness & volume alone cannot.

Richard Davy @davyclimate.bsky.social · 16d

Sea ice age is more than just a number — it integrates the dynamic + thermodynamic processes shaping Arctic sea ice. Unlike area or thickness, it can’t easily be tuned in models. Age emerges from the cumulative history of growth, melt & drift. A tough benchmark for climate models.

Richard Davy @davyclimate.bsky.social · 16d

We have a new paper out today taking a fresh look at sea ice age, showing how this variable offers new insights into Arctic climate change:

I'll be talking this afternoon about challenges in interpreting and making fair comparisons of sea ice age between climate models and observations, and demonstrating one way to resolve this using a common definition of sea ice age (paper out soon).

If you had the opportunity to educate the sustainable investing community about one fact, what would you want ensure it knew, above all else? My nomination: The large-scale, economy-wide asset devaluations that economists & climate scientists say will ensue if we fail to accelerate decarbonization.

Agreed! It’s really important to separate the role of natural variability (and its response to forcing) from forced-responses but it is a minefield for public communication

Hi Kevin!
There is sensitivity to those standout years but there is also a clear signal of natural variation in sea ice loss and arctic amplification that show a strong peak in the mid 2000s
