大堡礁：气候变化的活体档案

Stretching over 2,300 kilometers, the Great Barrier Reef is the world’s largest coral structure—and visible from space.
Corals build limestone skeletons over millennia, creating layered records of past ocean temperatures and acidity levels.
Mass bleaching events since 2016 have damaged two-thirds of shallow-water reefs, mainly due to marine heatwaves.
Indigenous Australian rangers monitor reef health using drones and traditional ecological knowledge of fish migration patterns.
Restoration projects now transplant heat-tolerant coral fragments grown in labs onto degraded sections of reef.
Runoff from sugarcane farms carries nutrients that fuel algal blooms, smothering young corals and blocking sunlight.
Australia’s Reef 2050 Plan includes stricter water quality targets and bans on dumping dredge spoil near sensitive zones.
Citizen scientists log sightings via apps, helping researchers map recovery rates after cyclones and crown-of-thorns outbreaks.
