Ominous for the this El Nino...Will be possibly the strongest one anyone alive has seen.
After a nearly month-long plateau Nino3.4 region temperatures (ONI) are on their way back up. We've now surpassed 1982/1983 and are only behind 2015/2016 in terms of maximum daily values. And its only early September.
It has been a while, but I have a summary of all the activity at Anak Krakatau over the last few days. Long and short: big explosive eruption, but not out of character for the volcano (or Indonesian volcanoes for that matter). It is a hot air travel mess, though: eruptions.site/2026/09/07/s...
September 2026 Eruption at Anak Krakatau
Location: Anak Krakatau, Indonesia Situation: Anak Krakatau, literally “child of Krakatau” has had some large explosive eruptions over the past week including ash plumes that reached ~5…

It's one of the classic stories of biogeography, in textbooks: Ratite birds stopped flying, were trapped on Gondwana, and along for the ride as the supercontinent split. Hence ostriches, emus etc. live in different places today Or maybe not? @callanbentley.bsky.social youtu.be/ZU603DQbgVE?...
Does ratite bird evolution tell the story of Gondwana's breakup?

New video! Wherein @stevebrusatte.bsky.social & I talk about the evolution of ratites & other flightless #birds, and how the classic idea they faithfully record Gondwanan breakup cannot be true! youtu.be/ZU603DQbgVE ⚒️🪶

Hellbender (giant salamander) nesting season is in full swing! Having a blast working with this research team to understand the connections between water quality + hellbender behavior, nest success, & population dynamics to inform the conservation of declining populations. #BioGeoBender #PACSP💧🧪🌎
Lapilli raining down on an Indonesian fishing boat ⚒️
Uitbarsting #Krakatau: de video van een vissersbootje op een steenworp afstand van de vulkaan terwijl het te maken heeft met een dikke uitval van as en #lapilli. In de laatste 10 seconden is ook de uitbarstingskolom te zien die wordt geproduceerd door de explosieve activiteit.
During the ongoing eruption of #Krakatau in Indonesia, 10-minute JMA Himawari-9 True Color RGB images today showed a broad lower-altitude area of volcanic ash (shades of brown) along with pulses of higher-altitude volcanic clouds (a mixture of water vapor, ash and SO2).
Cville people: I'm co-leading a First Saturday birding walk at Ivy Creek Natural Area this morning, 7:30am start. We have binoculars to loan out. Join us! 🪶
LET THERE BE BIRDS! #birds #fall #migration
Geotweeps, do you want a brief cameo in an upcoming subduction related video? If so: send me a short cell phone movie clip (landscape orientation, not "portrait") of you doing the "subduction" arm movements with your hand. No explanation, just 3 seconds of the "one arm goes under the other" motion.

It's another H O T one, Charlottesville. 🥵 ...But the good news is that both the temperature and the heat index are forecast to drop over the long weekend.

I cleaned up the smaller specimen of rock that I collected in this hike over the summer in the Gallatin Range of Montana. Now it joins my teaching collection. ⚒️
Hiked up Sourdough Canyon south of Bozeman, in the Gallatin Range, to view this amazing garnet-bearing amphibolite. ⚒️
This is pretty fucking wild. I had assumed in a worst case scenario he would target blue zip codes and toss ballots based on technicalities but this is even worse than I imagined.
