2016 was no doubt one of the most perilous years for Australia’s iconic Great Barrier Reef. Though the year has already left, the unpredictably scorching temperature damaged the entire 700 kilometer (496.4 miles) long aquatic ecology. Now a team of international scientists has warned that, despite all the measures and recovery programs, the damaged coral reefs will never be as pristine as it was earlier.
Various parts of Great Barrier Reef – the iconic World Heritage Ecology of Australia will never recuperate from the harsh impact of unseasonably warm ocean waters, which was caused by the last year’s unexpectedly hiked temperature. As warned by the scientists on Thursday, over the year, the issue of global warming has been intensifying, and gradually more and more World Heritage Sites are coming under rehabilitated danger of temperature hike of oceans.
As stated by the scientists from ARC Centre of Excellence for Integrated Coral Reef Studies, the threat of temperature hike has been there since long. But after last year’s bleaching event, the risk of damage to reefs has taken a step forward, and from the recent spike in sea temperatures, it is confirmed that, if global warming has not been capped, it will soon completely extinct the Great Barrier Reef. As shown in the statistics of ARC Centre of Excellence for Integrated Coral Reef Studies, hot water of oceans around the Great Barrier Reef slaughtered nearly two-thirds of the entire 700 kilometer (496.4 miles) spread of coral reefs last year. In 2016, the temperature of ocean water unexpectedly hiked, and the hot water caused the coral to force out the algae living inside them, and this event is known as Coral Bleaching. As a result of algae expelling, the corals left their colourful look and turned into ashen.
The researchers also warned that the measures like restraining the overfishing near the site and improving the quality of water would also not be able to bring the pristine look of the reefs back. Human being needs to curb the global warming and emission of greenhouse gasses for rescuing the reefs from the harsh impacts of bleaching.
According to Janice Lough, a senior principal research scientist at the Australian Institute of Marine Science, and the lead author of the study, “If given some more time, coral reefs will be able to pull through the insensitive bleaching trauma. But if the problem persists, and the history frequently repeats itself, then the coral reef community will lose their capability to recover from bleaching.”
