"Largest analysis of reef health reveals equivalent of more than all living coral in Australia was lost in 2009-18"
"About 14% of the world’s coral has been lost in less than a decade, a study of the health of coral reefs has found.
In the largest analysis of coral reef health ever undertaken, scientists found that between 2009 and 2018 the world lost about 11,700 sq km of coral – the equivalent of more than all the living coral in Australia.
Meanwhile, the report, released by the Global Coral Reef Monitoring Network on Tuesday, found that reef algae, which grows when coral is under stress, soared by 20% between 2010 and 2019.
The report features data collected by more than 300 scientists from 73 countries across 40 years, including 2m individual observations."
