Here's another video of the meteoroid - "Ach wie cool, unsere Kamera auf dem Sportplatz Kleinenbroich hat den Meteoriten eingefangen:"

A new space race could turn our atmosphere into a ‘crematorium for satellites’ Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

The authors "estimate that a ... teragram (one billion kgs) of alumina accumulates in the upper atmosphere – enough, alongside launch emissions, to significantly alter atmospheric chemistry and heating in dramatic ways we do not yet understand."

This is incredibly on point.

Spot oil prices grab the news, but it’s the impact we’re about to witness to petrochemical and derivative production that should really scare the shit out of folks.

It’s the sort of shock that could ripple through our global industrial economy for many months.

Landslide buries over 100 workers at coltan mine in Congo A mudslide has buried more than 100 people in a coltan mine in the east of the Democratic Republic of Congo. The landslide was triggered by heavy rainfall in the early hours of the morning in the town...

There are reports of yet another terrible landslide at the Rubaya coltan mining area in the Democratic Republic of Congo. As always, the losses are unclear, but may well exceed 100 people.

Poster for trip. Text reads ‘The 12th-13th century Cistercian Abbey of Strata Florida in Ceredigion is built from imported stone in addition to the local greywackes. Some of these freestones were also used for Llanbadarn church. Morning: Strata Florida Abbey. Introduction to the local and building stone geology by Tim and Ruth. We will then explore the abbey site to identify the different stone types in situ and their reuse in later buildings. Lunch Picnic at Strata Florida or lunch at The Black Lion, Pontrhydfendigaid. Afternoon: Llanbadarn Church. Imported stones are also seen in the fabric of the church. The interior also reveals a C12th Purbeck marble font, and a C10th Celtic stone carved from granodiorite from Cader Idris. Logistics Strata Florida is 19 miles from Aberystwyth and best visited by car. A taxi ride for 4 people from Aberystwyth railway station to Strata Florida would take 1⁄2 hour and cost approximately £40. A return taxi to Llanbardarn Fawr would cost a similar amount. The church is a 25 minute walk from the railway station.

Upcoming field trip with @geolassoc.bsky.social

Iran war threatens global helium supply Attacks on Qatar and the Strait of Hormuz remove one-third of the world’s helium from the market

The war in Iran has taken one-third of the world’s helium supply off the market. And if the conflict continues for more than 2 weeks, disruption for helium users could take months to resolve.

Tourists visiting the area tend to flock to the well-known spots (Antelope Canyon, The Wave, etc.) but with a decent pair of trail runners and some navigation skills, there are wonders to be found everywhere.

Apparently, I've trained bsky's "For You" feed to serve up posts that actually do interest me, both from folks I follow and otherwise. ✔️

Summary of inverse thermal histories of cratonic interiors in the context of Earth systems evolution

The extreme unevenness in the completeness of the stratigraphic, and by implication fossil, record is formed by many processes. Apparently the most profound gap— the Great Unconformity, is driven by tectonics.

The reason the Middle East has so much oil is the same reason it’s all stuck there now A continental collision trapped oil within what is today Iran. The same collision explains why that oil is trapped behind the Strait of Hormuz now

Late Glacial to Early Holocene Vegetation Reconstruction from the Wenas Creek Mammoth Site in Washington State The Wenas Creek Mammoth site pollen record, which extends from ∼20,000–10,000 cal yr BP, is significant given that few eastern Cascade paleoecological records span the Late Glacial to Early Holocen...

Happy #FossilFriday here is a wee climate paper that I coauthored. We found that 20kya eastern Washington was drying and warming up and chasing away all the pesky pine trees (ew, trees).

As usual with pleistocene stuff, my job was figuring out how old all the dirt was (age-depth modelling)

An ammonite looking stone object on a stand. The tag states it is 29.5 inches diameter, and claims it's 300 million years old, from the Atlas Mountains in Morocco. It's for sale for $1898.00

IANAP (I am not a paleontologist), but, this putative ammonite fossil, for sale in a shop in New Mexico, seems manipulated and not quite authentic.

Assortment of fossil marine reptiles on display at the main hall of the Center for Paleontological Investigations, Villa de Leyva

P.S the Center for Paleontological Investigations, where this specimen is displayed, holds an impressive collection of fossils - and it is just one of three museums in the town of Villa de Leyva! A window into an early Cretaceous marine ecosystem

Skull of Triceratops horridus!! The not so horrible Triceratops genera was one of the last ceratopsians and went extinct during the Cretaceous-Paleogene mass extinction. #FossilFriday ⚒️🧪🦖

It’s the Cambrian trilobite genus Olenellus from the Kinzer formation of Lancaster County, PA. There’s a surprising amount of Cambrian goodies from that formation but it’s hard to find outcrops. #fossilfriday
