Where do our CO2 emissions come from, and where do they end up? I made this little summary - and you can see why reducing the use of fossil fuels remains the most important tool we have for slowing climate change:

How old is the sea ice in the Arctic, and why does that matter? We’ve just released a new sea-ice age dataset covering 1991–2024. It helps researchers track the decline of older, thicker ice & improve climate studies, model evaluation & safe traffic in the region. @met.no nersc.no/en/features/...

The tool uses ECMWF’s 51-member seasonal ensemble and summarises the range of possible conditions each month. In the time series you see the 5th, 25th, 50th, 75th and 95th percentiles, so you get a sense of the spread.

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.

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 · 06/10/2025
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.

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.

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 · 24/09/2025
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 · 24/09/2025
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.

Summer 2024 featured unprecedented warmth in the European Arctic, causing melting of 1 % of the total ice volume on Svalbard. Bad news is that in 2100 and even in the optimistic SSP1-2.6 emission scenario, 50% of the future summers will be warmer than 2024. www.pnas.org/doi/10.1073/...
