Warming oceans can disrupt coral oxygen supply and trigger coral death

A new study from the University of Copenhagen shows that marine heatwaves can disrupt microscopic moving structures on the surface of reef-building corals that support their oxygen uptake. When seawater temperature crosses a critical threshold, this oxygen supply mechanism collapses, increasing the risk of coral death.
