> Also, sea levels haven't risen. There are thousands of pylon markers all over shipyards that are from 50 to 100 years old and haven't moved.

How exactly are you supposed to know the sea level was 6" lower from looking at an old pylon?

> This one is almost as preposterous as the ocean becoming acidic. It's not, simple chemistry can bring up the titration curve of seawater.

In the past 20 years, the ocean's oH has fallen by .05. You can buy a water pH tester that's accurate to .01 for $12 on amazon. It would have been, and still is, trivial to disprove a conspiracy that oceanic pH is rising. Nobody has. You can even do it yourself! Book a Hawaiian vacation, rent a boat, and go take some measurements around the place. Check it for yourself.

> But if you Google it, you will see a million pages talking about acidification of the ocean yet incredibly, no data on the PH of the ocean.

Wow, sorry to hear that! Here's some. That's from the Aloha station's measurements. They even have a neat little interactive tool to go through every single measurement they take! If you want something a little easier to look at, here's a graph, here's another, here's one for more places, and here's one of the entire planet. Man, they really are devious making it so hard to find their data to double-check!
