YouTube video by Arctic Circle Is the AMOC Shutting Down? - Atlantic Meridional Overturning Circulation

The risk of an #AMOC shutdown - explained in 15 minutes at the Arctic Circle in Reykjavik on Saturday.
I had the honor of presenting a letter by 44 experts warning of that underestimated risk to the Icelandic 🇮🇸 climate minister Guðlaugur Þór Þórðarson.

How clear and simple data visualizations bring the climate crisis home Climate change is a slow-moving disaster. We need graphics that capture both its pace and its impact.

Data visualizations are some of the most powerful tools in a climate science communicator’s playbook. However, designing visuals that are clear to the public and policy makers is not a straightforward task, writes @rachitdubey.bsky.social .

So, what works?

People tell me nobody wants to look at climate curves anymore, yet here we are!!! Please enjoy our interactive journey through 485 million years of climate history and dive into the fascinating and important work of paleoclimate scientists.

SveltePlot logo with the website address https://svelteplot.dev and a few example plots in the background

Last week I had the pleasure of finally releasing the #SveltePlot alpha version during my talk at the #SvelteSummit in Barcelona. It's a new visualization framework for @svelte.dev that I've been working on for the past 18 months, so it's about time for a 🧵

The launch of SveltePlot

stoked for svelteplot.dev, launched on stage just now at #sveltesummit by @driven-by-data.net

I‘m really excited about that! I’m sure you gonna create something good, Gregor.
I’m currently very happy with Layercake, but that might be a different use case.

A light blue diagram depicting the sea, with the water's surface at the top, and just below it is an outline of the Mary Rose, with the depth (12m, 40ft or 6.7 fathoms). There is a line showing the seabed, which takes a rapid dive into the vertical...

On the anniversary of the sinking of the Titanic, we thought we'd answer a question that's often asked,

"If they raised the Mary Rose, why not raise the Titanic?"

Allow our scaled diagram to explain...

That’s very good to know! Thanks for pointing that out.

Ausweisung von Palästina-Aktivisten wohl rechtswidrig Berlin will vier Personen abschieben, die an einer Uni-Besetzung beteiligt waren. Aber die Polizei ermittelt noch. Darf die Ausländerbehörde vorpreschen?

Propalästinensische Aktionen: "Migrationsrecht genutzt, um missliebige Leute zu vertreiben" Berliner Behörden wollen vier Personen ausweisen, die an Aktionen gegen Israel beteiligt waren. Alexander Gorski vertritt zwei von ihnen und spricht über die Vorwürfe.

I'm very pleased to share Tunnel & Fortress, a new live coached training series bringing the art of system administration to those with no prior experience in the field. Participants will deploy, garden & harden servers to keep their communities safe.

#exitbigtech

The Wikimedia Foundation, which owns Wikipedia, says its bandwidth costs have gone up 50% since Jan 2024 — a rise they attribute to AI crawlers.

AI companies are killing the open web by stealing visitors from the sources of information and making them pay for the privilege

I’m thrilled to bring together two institutions that shaped my work: BarabásiLab & metaLAB (at) Harvard.

On June 11–12, 2025, we’re hosting Data | Art—a conference on how data entangles with artistic, scientific & curatorial practices.

We have a stellar lineup of speakers! More soon: data-art.info

*Visualising climate science*
by Angela Morelli

Visualisation is a powerful tool for navigating the complexity of climate change. However, visualising climate science can confuse, misinform or polarise.

Cartogram of 299 German election districts

For the German election we wanted to use a cartogram of German election districts but didn't find anything good, so we created our own. Here's a little nerd thread how the final algorithm worked 🤓 🧵 #gis #cartogram #election #datavis #cartography

Also a great example of using helper visualisations in the process of creating a visualisation.

Fixing the outer districts is such a good idea!

Thanks so much for sharing. Very clever approach.

Ah, and inauguration crowd photos.

The „1 million Covid death“ feature by the NYT.

„Voter shift maps“ used for example by NYT.

Visualisation with emojis became a category.

I’ll find the links in my collection later at home.

If you are thinking about general types, I would also suggest the usage of satellite imagery with before/after (Gaza, Ukraine, wildfires) or as static images (Uyhur labour camps).

Then the visualisation used by Apple activity on the Apple Watch became quite iconic.

Hockey Stick graph became pretty relevant.

The ocean water temperature year charts were also very present.

Unpic 1.0 – Unpic Introducing the first version of Unpic: image components for every framework

I am very excited to announce Unpic 1.0 🎉

As easy as an <img> tag but generates all the right attributes and styles for a responsive image. No downloading and no build-time resize

• Components for ten frontend frameworks
• Support for 26 image providers, now with type-safe transforms for every one

+1 for RSS feed.

this is so good. this is so so so good. i'm running around my office screaming the lev manovich quote about how software is ideology

I recommend adding flower pollen and rosehip powder to the mix.

Lovely example of how weird real-world data is. I put all 55 million points in Overture maps into a Nomic Atlas map. Lots of points spuriously appearing in the ocean. But the 1° square around 'null island' (0° lat, 0° long) is suspiciously clear -- someone has cleared out bad data just there.

@moritzstefaner.bsky.social, reminds me of your solargraphy and I thought you might like the visualisation.

This image shows the hourglass shape of the nights shortening and lengthening from winter to summer and from summer to winter, passing clouds, the Moon passing through the night sky every month (diagonal bands) and the Sun climbing higher in the sky during summer.

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography

Why I'm quitting the Washington Post Democracy can't function without a free press

Anne Telnaes, Pulitzer-winning editorial cartoonist for the Washington Post, has resigned.

The paper censored a cartoon that criticized billionaires.

Democracy dies in broad daylight, too.
