Great Barrier Reef Faces Unprecedented Threat from Rising Ocean Temperatures

A recent study reveals that ocean temperatures around the Great Barrier Reef have reached their highest levels in 400 years, largely due to human-induced climate change, Al-Jazeera reported yesterday.

Researchers warn that this iconic ecosystem, spanning 2,400 km (1,500 miles), may not survive unless global warming is curtailed. The study highlights that since 1960, temperatures have increased annually, with significant spikes during mass coral bleaching events, which have occurred five times since 2016.

Co-author Benjamin Henley from the University of Melbourne expressed deep concern, stating, “The world is losing one of its icons.” The reef, home to 600 coral species and 1,625 fish species, contributes approximately $4.2 billion annually to Australia’s economy.

Despite the United Nations’ recommendation to list the reef as an at-risk world heritage site, Australia has resisted, fearing negative impacts on tourism. Scientists emphasize the urgent need for action to protect this vital marine habitat.
