are coral reefs going extinct in 20 years? It is easy, therefore, not to notice the perilous state they’re in: we’ve lost 50% of coral reefs in the past 20 years; more than 90% are expected to die by 2050 according to a presentation at the Ocean Sciences Meeting in San Diego, California earlier this year.
Will coral reefs not exist in 20 years? Over the next 20 years, scientists estimate about 70 to 90% of all coral reefs will disappear primarily as a result of warming ocean waters, ocean acidity, and pollution. Expand that out to 2100 and it’s “looking quite grim,” says Renee Setter, a marine scientist at the University of Hawaii in Manoa.
Will coral reefs be gone by 2050? According to the report, left unchecked, combined local and global pressures will push 90 percent of coral reefs to threatened status (all non-blue colors) in less than 20 years (by 2030) and nearly all reefs will be threatened by 2050.
What will happen to the coral reefs in 2030? By the 2030s, our estimates predict that more than 90 percent of the world’s reefs will be threatened by local human activities, warming, and acidification, with nearly 60 percent facing high, very high, or critical threat levels.
