NEW: We've tracked the world's largest iceberg, A23a, and it's on the move again!
It travelled along the seafloor ridge from the Filchner Ice Shelf to past South Orkney islands, pushed by currents, and is now in deeper waters en route to South Georgia.

It's time to log off. People are ingesting too much negative news, and it’s not only affecting them personally but impacting society at large. Psychology experts say you need to know your limits—and when to put down the phone. wired.trib.al/mrzI97V

NEW: One of the worst methane leaks ever recorded revealed.
Using satellite data, scientists estimate 127,000 tonnes of methane escaped from an exploratory well in Kazakhstan.
We analysed @planet satellite images to understand exactly what happened, from the blowout to its fix

Being a quiet New Year's Day I thought I'd take a quick look at what the longest road and street are in Ireland. I downloaded the data from geofabrik and processed it using Osmium and GDAL then ran a few SQL queries in PostGIS. The results were disappointing (1/3)
The reason they were disappointing is that the longest streets and roads were colloquial names such as the below. OSM refer to it as 'South Perimeter Road' whereas the actual road signs (and MapGenie) refer to it as the 'R108' (2/3)

About 1.2 million people die from tuberculosis every year.
Until now, however, we didn't cover this infectious disease on @OurWorldInData, it was an important gap in our publication.
@salonium and @f_spooner changed this. Here is our new page on TB:

Et si les villes devenaient des montagnes, collines et plateaux, et les campagnes des mers ou des lacs ?

New paper just dropped (I think that's what you say) on Valeriepieris Circles, aka Yuxi Circles
"The Valeriepieris (VP) circle is the smallest circle containing half of the world's population."
It's very cool and does it for countries as well 🤓🥳⬇️

Day 27/28 of #30DayMapChallenge: Dot / Is this a Chart?
To finish off my maps for this month's challenge, a somewhat experimental visual of NZ Wikipedia articles by view count, as tagged in OpenStreetMap.
ALT An abstract map showing dots representing the locations of Wikipedia articles in New Zealand. Dots are sized based on the number of page views the article has had since 2020.
