Two recent articles suggest a grim future if ocean acidification is allowed to continue at current rates. Oceans absorb much of the carbon in the atmosphere and as we increase atmospheric CO2, the oceans grow progressively more acidic. A new study published in Science suggest that ocean acidification is now, in all likelihood, occurring faster than it has for at least 300 million years.
Sea Changes: Ocean Acidification Is Worse Than It’s Been for 300 Million Years
Why does ocean acidification matter? The UK’s Dr Jason Hall-Spencer has been studying volcanic vents in the ocean floor. These vents naturally acidify the waters around them. Dr Hall-Spencer has been documenting the effects of acidification on local life. His work suggests that suggests our oceans could lose perhaps 30% of their biodiversity within this century.
