Regional variations in sea temperature can make all the difference between a coral reef suffering major bleaching or surviving as a refuge for corals, new research shows.
Mining social media posts from tourism hotspots such as coral reefs could turn tourists into environmental citizen scientists without them even realising it.
Coral bleaching on the Great Barrier Reef could lead to increased vulnerability of Queensland coastal cities and towns, and not only through its impacts on the tourism industry.
Amid fears for the world's coral reefs, the UN World Heritage Committee has issued its most wide-ranging statement so far on protecting heritage sites from climate. But the problem doesn't end there.
