Effects of environmental change on the Great Barrier Reef
Short term
Coral bleaching
Rising sea temperatures
Intensified climate
Long term
Rapid, human-induced climate change
Increased severity of severe weather events
more freshwater and sediment further out from the coast and on to the Reef.
Intense cyclones can destroy and weaken reef structure
Ocean acidification
Changes in the ocean's chemistry
