Science and media outlets claim ocean acidification is happening due to increased carbon dioxide in the atmosphere. But objective data show the ocean is far from acidic according to Dr. Caleb Rossiter, executive director of the CO2 Coalition and a statistician who has studied climate change closely.

Host Anthony Watts and Rossiter talk about how a pH of 7 is considered neutral, with anything below 7 considered acidic. Ocean pH averages 8.1, which is alkaline rather than acidic. Although climate models suggest the ocean’s surface pH may have dropped from pH 8.2 to 8.1 since 1750, that change was never actually measured.

The pH drop from 1850 is merely a modeled conjecture. The concept of pH was first introduced by in 1909, and agriculturalists first developed field instruments to measure pH in the 1930s.
