Great Barrier Reff is named for its vast size and its role as a natural barrier along the coast of Queensland, Australia. It now faces a menacing threat with a sudden 400 years temperature rise in Great barrier reef ocean.

Over the last decade, it has resulted in more mass bleaching events of the coral. Scientists in Australia who have examined the skeletons of coral and historical data say the evidence is clear: the reef is in danger, and the government has to act now against climate change after 400 years of temperature rise in the Great Barrier Reef Ocean.

The Great Barrier Reef, once an epicentre for aquatic biodiversity, has experienced mass coral bleaching in just the last 9 years. The scientists examined long Coral core samples drilled out of the bodies of centuries-old Coral. These contain chemical clues that reveal how warm the water was during the life of the reef combining this with historical sea temperature records showed that in just the last decade, temperatures around the Great Barrier Reef were the warmest of the past 400 years, the highest surface temperatures.

“These changes – from what we’re seeing so far – appear to be happening too rapidly for the corals to adapt to, so it really threatens the reef as we know it,” said McGregor, a climate researcher at the University of Wollongong.

Although terrible news for the reef-bleached heat, stressed Coral could recover if the current rate of global warming continues and the high temperatures don’t relent, it won’t have a chance to recover.

The evidence points to the slow demise of the Great Barrier Reef. At this point in time, governments and environmental organizations need to step in and recognize a world heritage site at risk. We must move away from fossil fuels as soon as possible and cut back on the use of carbon methane and other heat-trapping gases in the atmosphere.

Action must be taken now to have a fighting chance against climate change. The preservation of this world heritage site is not only crucial for its own survival but also for the health of our global marine environment. The time to act is now to ensure that the Great Barrier Reef can continue to be a beacon of oceanic wonder for future generations.
