Giant Clam Shell Reveals a 200-Year Climate Record of the Great Barrier Reef
A giant clam shell has provided scientists with a rare month-by-month archive of environmental conditions on the Great Barrier Reef dating back two centuries, offering a sharper view of how the reefโs climate has changed over time. The finding strengthens the scientific case that todayโs marine heat stress is unfolding against a long backdrop of natural variability, but at a pace and intensity that now threaten reef resilience.
