Oceans are becoming more acidic
Oceans absorb vast amounts of CO2, becoming 30% more acidic since 1750, endangering vital marine life and ecosystems that support global food security.
Our oceans absorb a quarter of all human-produced carbon dioxide, a process that helps regulate global climate but makes seawater more acidic. Since the Industrial Revolution, ocean acidity has increased by 30%, dropping the average surface pH from 8.2 to 8.1. This seemingly small change profoundly disrupts marine chemistry.
