New research says climate change could devastate nearly all of Earth’s coral reef habitats by 2100.
Among the existing, around 70-90% of coral reefs are likely to disappear in the next 20 years because of warming oceans, acidic water, and pollution, said scientists from the University of Hawaii Manoa.
They made their findings public on last Monday at an ocean sciences conference.
A few ecological activists and coral reef researchers have been working closely on the restoration of coral. They tried to grow live corals in a lab, and then put them back into aquatic environments to restore dying reefs.
But the researchers warned, this may not be adequate to save Earth’s coral reefs.
The new study made cluster on the ocean areas that would be best suited to this type of coral restoration. They also took into consideration factors like acidity, water temperature, human population density and fishing frequency.
After investigating the world’s oceans, they reached a serious remark: “By 2100, few to zero suitable coral habitats will remain.”
Unfortunately, existing ocean parts where coral reefs live today won’t be healthy by 2045. And, the circumstance of these environments is only likely to get worse by 2100, according to the team’s simulations.
Only a few sites will be viable for the restoration of a coral reef by 2100, like portions of Baja California and the Red Sea — even these aren’t suitable territories for reef because they’re close to rivers.
The researchers warned that human-made climate change was the big killer, a small part of the larger threat.
“Cleaning up the beaches and battling pollution are praiseworthy. But, we need to continue those efforts,” Setter said in that release.
“But tackling climate change is really what we need to be advocating for shielding corals.”
Coral reef die-off
Earlier, scientists warned that the world’s reefs are heading for “massive death” as ocean warming and acidification destroy entire swaths of reefs.
The Great Barrier Reef is a case for a large scale of “bleaching” events by above-average water temperatures in the last two decades.
Then, a drastic marine heatwave in 2016 and 2017 has destroyed about half of the corals on the Great Barrier Reef.
The Great Barrier Reef is such habitat for a diverse range of marine life.
Moreover, the extinction could cause ecological collapse as third of all sea species depend on reefs, experts warn.
Also, coral reefs protect the shorelines and coastal infrastructure.
In recent years, activists are in the quest of saving the reefs. Almost nothing will be unless we take drastic action on climate change.
