Happy #FossilFriday! 🐴🐘🐪💀 This gorgeous horse mandible comes from Brown County, Minnesota. It was collected by a friend of mine under permit in a state park earlier this year. The bone is deceptively heavy, suggesting it has been partially mineralized. Today, it will be donated to the Science Museum of Minnesota for study.

Unravelling The Dance Of Earthquakes - Evidence Of Partial Synchronization Of The Northern San Andreas Fault And Cascadia Megathrust
--
https://doi.org/10.1130/GES02857.1 <-- shared paper
--
“Previous paleoseismic work has suggested a possible stress triggering relationship between the Cascadia subduction zone and the northern San Andreas fault based on similar event timings. Turbidite successions correlated to both systems may support this hypothesis. Historic earthquakes in 1980 and 1992 in the Cascadia subduction zone and the 1906 earthquake on the northern San Andreas fault left turbidite records that are temporally well constrained by bomb-carbon−supported age-depth models..."

Ancient lakes in the Gobi Desert supported human life 8,000 years ago
The Gobi Desert today is one of the driest and harshest landscapes on Earth, stretching over northern China and Mongolia. Yet, a recent study published in PLOS One reveals that thousands of years ago, the desert was dotted with wetlands and lakes that nourished fertile ground for human life...

The Case for Letting Malibu Burn
Bushfires and sprawl: Man-made catastrophes and cultural narrativesThe lethal mixture of home ownership and the bush: Neighborhoods on fire.
"Since 1993. almost half of California’s new homes have been built in fire hazard areas...Commercial greed over common sense and the social good."The aristocratisation of the coast
"In a feverish buying and selling of land, the coast has become utterly transformed and unrecognizable. Each succeeding house, bigger and grander, takes the view of its neighbors in a kind of unbridled competition.… Once lost, paradise can never be regained.… Developers have bulldozed the Santa Monicas beyond recovery."

🦌#Minnesota #FossilFriday 🐂🦥🐴🐘🐪🐟🍃Remnants of deer and bison are common along many Minnesota rivers. Teeth, metacarpals, metatarsals, and some long bones withstand the erosive forces of rivers particularly well.
These specimens were all found during a single kayak trip this field season, along just a two-mile stretch of river in southern Minnesota.

Cool webstory by Reuters about future Iceland's and global volcanic eruptions to be triggered by retreating glaciers, when the weight of the ice is no longer keeping a lid on magma chambers.
Apart from neat writing, it's with video, lotsa photos, animated charts and everything one can think of to be included in #scicommtldr: yes, volcanic eruptions will increase with the retreat of glaciers. #Antarctica's volcanos too. #Earthquake activity has already been picking up in Iceland since 2021, also elsewhere in the #Arctic near glaciers, and around the globe.
It has happened before when Earth crawled out of the last #iceage into the #Holocene.
I might add: it happened not only at volcanos near glaciers. Rising #sealevel has triggered near-coastal volcanos, too, whether above or below the water. IIRC, a study on Stromboli proved it.
I personally think, #HungaTonga's eruption could have been one of the first submarine volcanos to have been triggered by #climateChange Another submarine volcano erupted near Japan in 2021 or 2022, forgot its name, starts with an O...
Not as huge an explosion like Hunga Tonga tho. -

Interesting.
From what I recall from a few papers I read, the Mediterranean, or #MENA, experienced droughts in the 4.2ky event.But figure 4 in the new literature review by #McKay et al 2024 shows a decidedly wet excursion for MENA: https://www.nature.com/articles/s41467-024-50886-w
They do mention the #Mediterranean and say, it were a complex and not at all clear case whether a drought was gripping the region or not.
So I pulled #d18O from cave #speleothem in the database " #Sisal3 " and plotted all those with okay resolution during the 4.2ky event.
The time span of the selection goes from 8.5ky to 2ky, like in McKay's paper.
My cave selection goes from longitude -9° to 85°E.
Locations are in the Google map, with the info whether it was dryer🔴 or wetter🌀 at 4.2ky.A 3-colour-coded heatmap for the 50th percentile of d18O shows orange as drought and blue as wet.
More info in the ALT texts.Conclusion: the mediterranean DID get dryer in the 4.2ky event. 🙂 🖖
-
My girlie chart with 490ky years of #Milankovic cycles, CO2, sea level, and the top line is d18O of a sediment core from within the #ColdBlob, see map. I think, it records AMOC shutdowns in the past.
Would be intriguing to know why it shut down. Eg, 427ka, "just" before the interglacial MIS11.
And why it not shut down during that very long interglacial which was ~as warm as the Holocene,
and had an ice-free West #Greenland (with a leaf found just 2 years ago at rock-bottom of an ice core from there),and why AMOC instead collapsed in the middle of the following #iceage.
The very long interglacial MIS11 with its ice-free West Greenland and stable AMOC throughout tells me that the amount of freshwater input from melting ice on its own isn't the trigger for a collapse. But instead, the speed at which freshwater is added: very slowly like during #MIS11 won't do it.
Also intriguing: why the stuttering motor during the last glacial before the #Holocene?
#d18O from sediment cores at other locations strictly follow the ups and downs of #sealevel and #CO2. This one site #IODP #U1308 is exceptional.

Happy #Minnesota #FossilFriday! 🦬🐪🦣🦥🦫🍃 What is the most common Bison bison specimen found in river gravels besides teeth in Southern Minnesota? It's usually a metacarpal or a metatarsal.
These stout solid bones survive well within a river's fluvial processes. Here are a few example specimens.🦴
