Coral bleaching is bad news for fragile marine ecosystems. Mass bleaching of corals on a wide scale is worse news still. Yet bleaching en masse reefs around the seas are, according to scientists who have surveyed bleaching records of 100 reefs collected between 1980 and 2016 from around the tropics….

As global warming continues to take its toll, corals in the Pacific Ocean are dying off en masse. Reefs in several areas have experienced alarming mass bleaching episodes, leaving large swathes of coral dead or near-dead. Corals are tiny creatures that live in colonies and require algae to provide them…

The increasingly frequent mass bleaching of corals, driven by climate change, has placed the very existence of numerous reefs at risk from Australia all the way to the Indian Ocean. And as water temperatures continue to rise and ocean water continues to acidify owing to global warming, there’s little cause…

First it was the Great Barrier Reef, off Australia, which underwent extreme mass bleaching that placed the very existence of many corals there in jeopardy. Now it’s corals in the Chagos Archipelago, a smattering of 60 small coral atolls, in the Indian Ocean that are likewise experiencing the threat of death by mass bleaching….

When it comes to corals in tropical waters, good news is hard to come by. Battered by global warming and pollution, these fragile creatures, and their ecosystems, are increasingly under threat of mass bleaching worldwide. Australia’s famed Great Barrier Reef may be doomed, and Malaysia’s own stunningly beautiful reefs, which are…

Australia’s Great Barrier Reef is one of the world’s natural wonders and its largest living structure. Now brace yourself: it’s in a “terminal” state of decline. Shocking news? Yes. But not all that unexpected, sadly. Two successive mass bleaching events last year and this year across much of the reef have pushed…

If you want to see the future of fragile marine environments being battered by climate change, look no further than Australia’s world-famous Great Barrier Reef. Last year the corals at the reef underwent an unprecedented mass bleaching episode, which killed off or visibly damaged huge swathes of coral for hundreds of miles….

Malaysia’s stunningly beautiful coral reefs have been at increasing risk of mass bleaching as a result of growing water temperatures. And things, the United Nations warns, are only going to get worse for corals everywhere, Malaysia included. In coming years and decades many reefs will experience not just episodic bleaching once in a while, which is…

Even with the parlous state of wildlife preservation, it is rare to witness the slow but seemingly inexorable death of entire ecosystems in real time right before your eyes. Yet that’s what’s happening to the region’s coral reefs far and wide. Australia’s Great Barrier Reef, a wonder of the planet’s…

Coral bleaching. The very term evokes something ominous – and an ominous development it indeed is. As water temperatures rise, often as a result of climate change-triggered heat waves, corals (fragile creatures as they are) begin to turn white. That’s because warmer water temperatures cause corals to shed the zooxanthellae…
