5. "The NSC has been gutted in a series of ideological purges, egged on by those who interpret expertise and experience as codewords for Deep State sympathies."

Which really describes every executive branch department under the current administration.

I enjoyed #6 and #1. The other pieces are sad. Well, the whole world is getting sadder.

(1) could have called out the components as they are named and the article would have been better. The M2 component is what most people need and use — typing this while peering over to the bay of Fundy... — relates to the largest lunar component with a period of 24h 50min.

Round the UK has some DAMNED weird tidal behaviour (sometimes the tide tables can't even give you the data for a high tide prediction and you have to work off the low tide only.

In the Baltic, it's usual to claim there's NO tides, but it's more the complicated effects of the land and weather mean that it's just not at all predictable as to WHEN and how much - which is somewhat inconvenient, since there ARE certainly reversing currents and they run hard enough to be inconvenient to small craft and reduce efficiency/increase fuel usage on large ones. Also the associated changes in water depth (going around is NOT FUN). You can make some decent general guesses based on the recent and predicted wind direction, but it's not like sailing in the Channel, Atlantic coast or even the North Sea ... it is somewhat annoying at times.

Round the UK has some [...] weird tidal behaviour

Eg Southampton has four high tides a day, since they come up both sides of the Isle of Wight.

We live on the Severn and further downriver there's the Severn bore.

I've recently discovered that there are about 20 tidal bores on UK rivers, including my local river, the Kent. Unlike the Severn, this bore is in the estuary, but the tide does have about ten miles to come in across flat Morecambe Bay.
