The Chinese host of a United Nations world heritage committee has defended a proposal to label the Great Barrier Reef as “in danger”, and rejected Australian government suspicion that China influenced the finding for political reasons.

It came as the Morrison government sought to use a new report by Australia’s marine science agency to argue there had been widespread coral recovery on the reef.

Group of reef and climate scientists say world heritage warning merited and Australia has not ‘pulled its weight on emissions’

Five of the world’s leading reef and climate scientists have thanked Unesco for recommending the Great Barrier Reef be listed as world heritage “in danger”, saying it was the right decision in part because Australia had not “pulled its weight” in reducing emissions.

The group of scientists, including the Australian professors Ove Hoegh-Guldberg and Terry Hughes, wrote to the UN body on Thursday saying the recommendation to downgrade the 2,300-km reef system’s world heritage status was “the right decision”.

Exclusive: Mass bleaching seen along Great Barrier Reef could mark start of global-scale event, expert warns

Rising ocean temperatures could have pushed the world’s tropical coral reefs over a tipping point where they are hit by bleaching on a “near-annual” basis, according to the head of a US government agency program that monitors the globe’s coral reefs.

Dr Mark Eakin, coordinator of Coral Reef Watch at the National Oceanic and Atmospheric Administration, told Guardian Australia there was a risk that mass bleaching seen along the length of the Great Barrier Reef in 2020 could mark the start of another global-scale bleaching event.

Planes will this week cover areas in the southern half of the reef that escaped earlier bleaching but may have undergone high levels of heat stress

The full impact of coral bleaching across the Great Barrier Reef will become clearer this week as aerial surveys of hundreds of reefs are completed in the bottom two thirds of the world’s biggest reef system.

An aerial survey carried out last week over almost 500 individual reefs between the Torres Strait and Cairns revealed some severe bleaching of corals closer to shore, but almost none on outer reefs.

With global heating damaging corals worldwide, experts find potential tool in ‘acoustic enrichment’ to recolonise reefs

Playing sounds of a healthy coral reef can attract fish back to reefs that have become degraded and abandoned, researchers have found.

Global heating together with factors such as pollution are causing widespread damage to coral and harming delicate reef ecosystems.

The 150 sq km field of floating rock was created by an underwater volcanic eruption near Tonga

A giant raft of pumice, which was spotted in the Pacific and is expected to make its way towards Australia, could help the recovery of the Great Barrier Reef from its bleaching episode by restocking millions of tiny marine organisms, including coral.

The pumice raft, which is about 150 sq km, was produced by an underwater volcano near Tonga. It was first reported by Australian couple Michael Hoult and Larissa Brill, who were sailing a catamaran to Fiji, on 16 August.

Australia’s global leadership on whale conservation will be tested as Japanese hunters move to a different hemisphere

Japan’s whaling fleet arrived back at the port of Shimonoseki on the weekend with a barbaric tally of 333 dead whales that are no longer swimming freely in the Southern Ocean.

If the work of the Japanese whalers is anything like last year, more than 100 pregnant females and 50 or so juveniles will have been killed. But from now on, things are different.
