Great Barrier Reef corals could become the target of mass bleaching, World News


For the fourth time in the seventh year, corals in the Great Barrier Reef may become the target of mass bleaching – the process by which coral reefs release algae from their tissues and turn white. A forecast from the US National Oceanic and Atmospheric Administration (Noaa) showed how heat builds up in various parts of the reef. He further highlighted how high it will be high enough for the corals to start bleaching by the end of January.

Dr David Wachenfeld, chief scientist at the Great Barrier Reef Marine Park Authority, said water temperatures are currently above average “almost everywhere”, with some areas warmer by 2 ° C.

In a Guardian report, he said: “The current situation is not what we want, but in a world with a changing climate, it is not surprising.

A spokesperson said the office’s ocean outlook “indicates increased heat stress on the Great Barrier Reef for the remainder of the year and January 2022, decreasing in February.”

Not only the Great Barrier Reef, but the corals of the Indian Ocean are also threatened with extinction.

Reef systems are at risk of disappearing by 2070, according to a study published in the journal Nature Sustainability.
This can lead to a huge loss of biodiversity, hampering the livelihoods and food sources of many people in neighboring areas.

For this reason, bleaching events are becoming more and more frequent.
