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.

Winter has arrived properly in Norway this week ❄️ After a few days of heavy snow it already feels like mid-season, so it’s time to look a bit further ahead.
I’ve built a small interactive tool to explore ECMWF seasonal snow forecasts for the Nordics:

Sarcasm aside, it's perhaps worth pointing out that the evidence suggests that weather disasters reduce economic growth for decades - the idea that there's rapid bounceback, or even extra growth stimulated by recovery, has proved wrong

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.

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.

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.
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.

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.

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.

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.
