Studies Show Elevated CO2 Reduces Calcification in Coral Reef Ecosystems
Two scientific experiments examined the impact of elevated carbon dioxide on coral reef ecosystems. A 2016 study on Australia's Great Barrier Reef found that increased CO2 reduced net reef calcification by 34% over 30 days. Separately, a 10-month Hawaii experiment showed an 86% decline in crustose coralline algae coverage under acidified conditions. Both studies highlight how ocean acidification, driven by CO2 absorption, can slow calcification and alter reef community composition, affecting reef structure and resilience.
