A paper published today in Climate of the Past reconstructs water pH and temperature from a lake in central Japan over the past 280,000 years and clearly shows that pH increases [becomes more basic or alkaline] due to warmer temperatures, and vice-versa, becomes more acidic [or “acidified” if you prefer] due to cooling temperatures. This finding is the opposite of the false assumptions behind the “ocean acidification” scare, but is compatible with the basic chemistry of Henry’s Law and outgassing of CO2 from the oceans with warming.
Thus, if global warming resumes after the “pause,” ocean temperatures will rise along with CO2 outgassing, which will make the oceans more basic, not acidic. You simply cannot have it both ways:
