Perfect pH answer. This is not my first pH rodeo. This is how climate alarmism works -- pick the most alarming scale -- and/or cherry pick data. Yes indeed, the ocean became less alkaline (and not more acidic like the Smithsonian said). This "less alkaline" cycle happens about every 100,000 years during Interglacial Warming Periods -- like the one we are currently in. And here we come to the bottom line -- these changes all fall within historic natural cycles. There is no climate emergency -- and there is no proof "man-made" CO2 has caused any climate to change.
