First report in 13 years shows damaging effect of warming ocean
A global analysis released on Tuesday found that 14 percent of the world's coral reefs were lost between 2009 and 2018, an amount greater than all the coral currently living in Australia's reefs. The report was released by the National Oceanic and Atmospheric Administration (NOAA) and partners including the Global Coral Reef Monitoring Network (GCRMN).
The largest global analysis of coral reef health ever undertaken indicates that rising ocean temperatures resulted in a 14% loss of global corals. The Status of Coral Reefs of the World: 2020offsite link report from NOAA and partners around the world also found indications of coral resilience in some locations, offering hope that coral reefs can recover if immediate steps are taken to curb future ocean warming.
This is the first report since 2008, which fills a significant gap in contemporary understanding of global status and trends in coral reefs. The analysis used data from nearly two million observations from more than 12,000 collection sites in 73 countries over a time span of 40 years (1978-2019), representing the work of over 300 scientists.
