This is remarkable. The world added more solar and wind capacity in 2024 than we added demand. 100% of demand growth PLUS 9% to retire dirtier sources. Cheap energy keeps winning. ember-energy.org/latest-insig...

How many trillions of dollars have been invested into this technology so far?
Google search for "austria hungary in space"

Google excitedly tells you about the 1889 orbital flight, and that by 1908 there was a Mars research output with 30 people.

Also, to wind up the #3 favorite post, for people following along with the database open in Google Earth, the two Devastator Creek slides are LS01466 and LS01467.

We saw so much other weird stuff during that fieldwork summer I'm still trying to process 32 years later. A whole large airplane wing lying in Meager Creek at NoGood Creek. People shooting the tops off beer bottles with a shotgun to open them. Apparent obsidian rinds from heating on landslide clasts

So really I'm picking Devastator Creek just as #3 based on my personal history and emotional connection to it, nothing more.
Also it may be that the glacier has retreated so much that it doesn't even buttress the unstable slopes anymore? Not sure on that. It's melted back a long way since 1930

Both of those Devastator Creek failures were caused by heat waves and rapid glacial retreat.

Anyways, as an undergrad in 1993 I spent a summer supporting Mats Jakob's PhD research and we spent a whole month camped at Meager Hot Springs. Here we are at Devastator Creek looking up the drainage

So back to Devastator Creek... why these ones? Devastator Creek is really neat. The volcanic peaks are so young that they are (or were) actually BUILT ON TOP OF GLACIAL ICE.
Can you guess why this is a bad idea? Cause we're killing the climate is why.

And on the north side of Plinth Peak the 2000 m north face is the cone of a very recent volcanic eruption, when one side of the volcano fell off and blocked Lillooet River, making the river cut down through it and create Keyhole Falls

If you look around the Meager Group you'll have no trouble seeing recent evidence of immense landslides like the 2010 Capricorn Creek landslides and debris flow

It's kind of a cheat because there are *two* separate large landslides here in the same drainage - Devastator Creek. 1930 and 1974. Both resulted in fatalities, and in 1930 debris flows which ran long distance down Meager Creek and then Lillooet River (moreso than 2010 Capricorn Cr slide)

I'm going to add #3 tonight because I'm out in the woods for work tomorrow....

'cause you always want to mass your troops in Kamchatka before you pass the sewer budget?
drewbrayshaw.bsky.social
like, mechanically grinding up wet limestone in the enormous blender of a major rock avalanche's path seems like a great way to make lime-rich mud deposits to me.
drewbrayshaw.bsky.social
idk about other landslides but Cheam slide scarp has that limestone unit with the Timber Camp linears and potential karst developed in it, and that's close to the failure plane. wouldn't be surprised if weathered, karstified limestone both contributed to slide and made marl in deposit

I was just talking about that with some folks last weekend! We don't have many such aqueducts or canals in BC, and it's the only one I can think of off the top of my head. It's a much more common thing in Europe.

Police in Airdrie, Alberta (just north of Calgary) say this driver hit a 17-year-old girl in a marked crosswalk, got out of the vehicle, and appeared to get upset at the teenager before driving away.

They released this video and are now trying to identify the driver.

Also, I missed out including this in the post above, Cheam Slide is LS01509 in the database.

The Cheam Lake wetlands, in the restored quarry, are a great bird sanctuary. It's also a no-dogs zone so I don't go there much these days.

(Also there's some potential hang fire off to the east side of the existing slide scarp so buying property down below is not a good idea no matter what price it's offered at)
