How much has ocean acidity increased since the 1800’s?

It becomes an acid. LISA SUATONI: Since the Industrial Revolution, the ocean acidity has increased by 30%. With mathematical models, scientists have demonstrated that if we continue to pollute as we are now, the ocean acidity will double by the end of the century compared to pre-industrial times.

Explanation:

The world's oceans are absorbing more carbon dioxide, as shown by the three sets of measurements in this graph. More carbon dioxide means increased acidity (lower pH). ... Over the last few decades, the amount of carbon dioxide dissolved in the ocean has increased all over the world, and so has ocean acidity.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
