Acid Test
Rising levels of acidity in oceans revealed - Environment - Scotsman.com
In some regions, acidity rose faster in the last two centuries than it did in the previous 21,000 years, a study has shown.
Measuring changes in ocean acidity is difficult because it varies naturally between seasons, years and regions.
Direct observations only date back 30 years, not long enough to reveal a meaningful trend.
So observations reveal nothing, must be proxies and models then.

Thing is though, sea waters alkaline, not acidic.

How the f**k did they manage to find out the acidity level thousands of years ago? F**king f**kers.
