"The severe impacts of the record temperatures on the surface of the water make the reef habitat condition go from bad to very bad"says the Authority, which is a government agency.
"Global warming is worsening and is the most serious threat to the long-term prospects of the regionshe continues. Major global action to respond to global warming is critical to slow ecosystem degradation and the reef's heritage value and help its recovery. "
TheAuthority of the Great Barrier Reef Marine Park specifies that the site is facing threats "multiple, adding and getting worse"citing agricultural run-off and the ravages of the purple acanthaster, a coral starfish that has proliferated due to pollution.
The Authority explains that this deterioration in the outlook for the Great Barrier Reef reflects the deterioration since 2014 of more portions of the complex that suffered in 2016 and 2017 two episodes of unprecedented bleaching of its corals, a phenomenon due to global warming.
