Gave a talk about glacier recession in the Andes yesterday and the title slide showing two decades of change turned some heads. Here's a better (worse?) one showing 47 years of ice loss in a small part of Patagonia.. 🧪❄️

Here is the Big Barn fault crossing the parking lot of The Woodlands High School in The Woodlands, Texas USA. It is a down-to-the-basin normal fault, a typical Gulf Coast growth fault. Faults like this are not seismogenic, but their continuous movement causes much damage to infrastructure and houses

For the second fiscal year in a row, NASA awarded ~20% fewer grants than the recent historical average. That's about 500 fewer grants going out to scientists around the country.

NASA has ignored recommended funding levels for planetary research & analysis for 15 years, according to a new investigative report by Mark Sykes (@coop.planetary-research.org). And for FY2025, it hasn’t even spent 50% of what it budgeted for R&A. 🧪🪐🔭 eos.org/research-and...

Chinook salmon have recolonised 88% of their historic range on the Klamath River, with more than 13,000 fish passing the old Iron Gate Dam site in 2025, up from 7,700 the year before. Two years after the dams’ removal, it’s going better than anyone predicted. buff.ly/pToC9gB #ShareGoodNewsToo

When you synthesize monazite with specific cations in a lab, you can make quite the rainbow. Here are La, Nd, Gd, and Yb monazites (technically xenotime for Yb, almost the same structure but different enough that it has its own name). Nd was always my favorite. #mincup26 #mincup #monazite

🔥 August 2026 not only beat the record for the warmest August on record, but it beat July 2023 for the warmest overall month on record for Planet Earth since 1940 - and likely the warmest during the entire Holocene. 😢

This is a very excellent explainer of the scientific reconstruction of the Nepal debris flow. Lots of interactive data and visuals in the report. 23 minutes between the glacial collapse/landslide before it reached the border station.⚒️

10:23 pm in Houston, eclipse on iPhone. Some clouds rolled in just after this. I have an earth and space science intro class this year and said I’d give a few points for a photo of the August 27 eclipse. One student submitted a photo last weekend.

An incredibly well-timed Landsat 9 pass captured the effects of yesterday’s catastrophic glacier collapse near the Nepal–Tibet border. The event was so massive that it was detected by seismometers around the world.

I'm very excited to share my latest paper about why Venus has no moon. In almost every scenario, a hypothetical Venus moon spirals inward and is destroyed at the Roche limit. Venus' lack of moon may thus be a natural consequence of its slow spin. arxiv.org/abs/2608.25036

Mineral Monday: Memorial: Dr. George Rossman By Dr. George Harlow His research focused on color in minerals, the effect of high-energy radiation on color, and the role of “water” (H2O, that is) in minerals, esp. when not part of the chemical formula. #MineralMonday #spectroscopy

Volcanoes are fascinating. Pictures, videos and articles of eruptions fill our social media feeds and newspapers. But can you believe what you read? Misinformation and rumours spread just as easily as facts. Misconceptions are easily created and hard to correct. @heatherkhandley.bsky.social

theconversation.comDuring eruptions, misinformation can spread further than ash. How can we spot it?From scary headlines to recycled eruption videos, new research reveals how common misconceptions can fuel misinformation about volcanoes.

I’m with @polarrobs.bsky.social that glacial geoengineering ain’t gonna work for many reasons. This is a well-done report from @milesobrien.com, but it should mention that many climate scientists believe that if we don’t stop burning fossil fuels, we can kiss a lot of land-based ice goodbye.

Pretty good rocks. Although the sodalite is not from the UP - it comes from the north side of Lake Superior, so samples are nicely tumbled by the time they get halfway around the basin.

Mike Wiser@drmikewiser.bsky.social

Fun rock of the moment: yooperlite. It’s an igneous rock that contains inclusions of sodalite. That sodalite is fluorescent under UV light. Named yooperlite because of its relative frequency in the upper peninsula of Michigan

#Etna, 13 August 2026. Lava is some strange stuff. When advancing after having traveled a few kilometers, it will rather crumble forward, but if you record it in timelapse you do see a kind of flowage. All except the first few seconds of this video are 10-20 times normal speed.

Impressive! I wonder how common these kinds of videos will become - we are also seeing a remarkable (and horrifying) influx of videos showing buildings shaking and then collapsing. (And of course, figuring out what's real and what is fake is an increasing problem.)

A new video emerged which seems to show a surface rupture in Yatsushiro, Japan following the M6.8 earthquake in July! Exact location of the video would be 32°30'04.0"N 130°38'29.9"E. Absolutely wild. Only the second ever video of a surface rupture forming after the 2025 Myanmar video! ⚒️🧪 #geology

I've been to all 254 TX counties, and Big Bend is the very best of Texas. The stunning, expansive desert landscape still feels untouched. It deserves to stay that way. It breaks my heart thinking about it being needlessly ruined for a f***ing wall. Here's some photos I've taken there. 🧵4/4

Ralph Lorenz—Huygens showed that Titan can be wet, even at low latitudes. As Dragonfly flies across Titan, the odds it’ll land in mud are low (<1%), and if so, the stickiness will be again to sticky wheat dough (and Dragonfly could still takeoff). #AOGS2026
