Climate change was responsible for the disappearance of nearly 14% of the world’s corals between 2009 and 2018, the Global Coral Reef Monitoring Network (GCRMN) reported.
In a report released Tuesday, the GCRMN said the state of the world’s coral reefs in 2020 “offers the most accurate scientific panorama to date of the damage caused by rising temperatures to coral reefs around the world.”
Quoted in a statement, the report, which was based on data collected from 12,000 sites in 73 countries, also points to other local pressures such as overfishing, unsustainable coastal development and a decline in the quality of the sea. water.
He thus reveals that “between 2009 and 2018, the world lost nearly 14% of the coral on its coral reefs, which represents nearly 11,700 km2 of coral, a quantity greater than all living coral in Australia” , noting that “although reefs cover less than 1% of the ocean floor, they are home to at least a quarter of all marine life, as well as being crucial habitat and a source of protein (and) medications “.
Calling for global greenhouse gas emissions to be reduced as quickly as possible, the report assures us that “climate change is the greatest threat to global reefs”.
