2 Sept 2019 - The Great Barrier Reef's outlook has been officially downgraded from poor to very poor due to climate change.

Rising sea temperatures thanks to human-driven global warming remain the biggest threat to the reef, a five-year Australian government report says.

Actions to save it "have never been more time critical", the report reads.

Stretching over 2,300km (1,400 miles), the reef was designated a World Heritage site in 1981 for its "enormous scientific and intrinsic importance".

But in recent years the reef has been increasingly damaged by warmer seas which have killed off coral and affected its long-term health.

Unesco's World Heritage Committee is due to consider adding the reef to its list of sites that are "in danger".

The massive report documents the condition of the reef and its outlook for the future.
