At the peak of a winter flood Scotland pours about 5,300 cubic metres per second into the sea. At the summer low it is still running a thousand. A five-fold swing is mild for a country this wet: the Atlantic delivers rain all year. Data: @copernicusecmwf.bsky.social #Scotland #rivers #hydrology

I LOVE this globe, which I found in the GEOMAR lobby (a German ocean research institute) this week. Exaggerated topography of both land and sea, showing the big picture and the beautiful intricacy. I want one!

Some misguided fool left this Rand McNally extra large road atlas by the curb so I had to rescue it. Interesting how New Hampshire and the very unHampshire-like Vegas Strip share a page.

One of my 9-11 memories is of how George W Bush went into hiding for over a week. Then the media buried the story because it didn’t fit the strong leader bravely sending us off to war narrative.

This is wildly irresponsible of Google - allowing people to create AI generated satellite images. Satellite imagery has always been such a useful and reliable source because it came from reliable sources, but now Google is messing with it at source. www.digitaldigging.org/p/how-to-pla...

67 boat strikes 221 people killed EXCLUSIVE: Operation Southern Spear has not reduced the volume, availability, purity or price of cocaine arriving in the U.S., according to an internal DEA assessment and a closed-door Pentagon briefing for senators, and has made enforcement more difficult
washingtonpost.com
67 boat strikes. 221 dead. The cocaine hasn’t slowed, officials report.
The president says Operation Southern Spear has virtually ended drug trafficking by sea. Pentagon and DEA analysts have concluded otherwise.

To carry 50,000 people per hour in each direction, a city needs a 175m wide road for cars. Even if those cars are electric. And then there’s all the parking. OR a city can move A LOT MORE people in a lot less space, with A LOT LESS public money, emissions, pollution, noise etc. Choices. Simple.
Graphic showing a 9 m wide track for metros can move as many people as a 175 m wide, 7 lane road for cars.

GIS-Pro is coming to Milwaukee this fall so I'm looking at maps. Perhaps someone can tell me what this elevated highway accomplishes other than cutting off easy access to the train station and the waterfront, dividing downtown and making the entire area less attractive.
