I have a feeling that whoever put this together did so without any sense of direction, any consideration for experimental control or any other way of offering something in lieu of proof, anything. Just anything, period. This person that did this study and wrote about it has a fucking cabbage for a head. That's how that works.

That doesn't sound right, surely they can use the data from more stations than that? Canada has 125+ years worth of tide and water level data from thousands of stations, maybe NASA should talk to them? It's free to download per water level station, or you can submit a request for the full dataset. (Disclosure: I worked for a time with the team that processes incoming marine data and digitizes historical log books.)
no time of day is not too early to read that horse shit.
Computer Science is merely the post-Turing decline in formal systems theory.
