Climate variations over the last 2000 years provide valuable context and help answer questions about how unusual the recent changes are.

Now with added global sea level rise: climatelabbook.substack.com/p/climate-ch...

I dunno if this crab is angry, but the clam might be feeling crabby! 🦀
A lone crab sits atop a clam in an aquarium habitat. A carpet of bright purple sea anemones cover the rocks along the habitat floor.

What are the most exciting trends you’re seeing in spatial data science lately?
Some of mine:

- New file formats (e.g. #GeoParquet)
- Geospatial DBs (e.g. #DuckDB + spatial)
- Global discrete grids

What would you add?

#Geospatial #GISchat #RSpatial #GeoPython
A discrete global grid (DGG) is a mosaic that covers the entire Earth’s surface. Mathematically it is a space partitioning.

It’s baby octopus season 🐙🦑

Saw this little guy last night with the Salish Sea School in Anacortes, WA as part of their free community dock walk I volunteer as an interpreter for.

We can tell it is a giant pacific octopus from the single line of chromatophores on each arm.

Bsky hasn’t heard the story about the time that I was giving a virtual colloquium to the Aspen Center for Physics in September 2020 and Lawrence Krauss, Geoff Marcy, Christian Ott all attended as a group

ACP now has a policy that would prevent this from happening, because of that incident 🔭

BREAKING: We won a court order blocking Pres. Trump’s attempt to stifle First Amendment rights and gain political control over the University of California system.

The President can't force people to think or believe only the way he does. This is a key victory for our clients and the rule of law.

ZOMG LET ME TELL YOU ABOUT THE SHALE

Okay, so the Burgess Shale is a fossil bed in British Columbia that contains a whole bunch of fossils of weirdass creatures from the Cambrian era, over 500 million years ago. But the great thing about the shale is that it has fossilized SOFT PARTS!
