All is not well in Lakshadweep. Why the island could be in big trouble

India Today  

Lakshadweep renowned for its pristine atolls, breathtaking reefs, and idyllic inhabited islands is currently grappling with an unprecedented crisis as widespread coral bleaching has been recorded due to marine heatwaves. Marine heatwaves are extreme weather events that involve prolonged periods of abnormally high ocean temperatures, often exceeding the 90th percentile of typical regional ocean temperatures based on historical data. The …

Scientists detect coral bleaching in Great Barrier Reef's far north

Hindustan Times  

Australian researchers have found coral bleaching around six islands in the far northern parts of the Great Barrier Reef, after a government agency said last week a major bleaching event was unfolding across the world's most extensive reef ecosystem. Great Barrier Reef Scientists at the James Cook University said on Friday they found only a few relatively healthy areas, mostly …

Hindustan Times  

Corals are marine invertebrates, which are part of the group anthozoans, the largest class of organisms within the phylum Cnidaria, which also includes jellyfish and anemones. “This loss leads to the bleaching effect and, if prolonged, can cause coral mortality,” said Apte, “however, coral bleaching doesn't immediately result in coral death.” Over the last two decades, the Indian Ocean's sea …

Scientists say Florida Keys coral reefs are already bleaching as water temperatures hit record highs

Associated Press  

FORT LAUDERDALE, Fla. — Some Florida Keys coral reefs are losing their color weeks earlier than normal this summer because of record-high water temperatures, meaning they are under stress and their health is potentially endangered, federal scientists said. Surface temperatures around the Keys have been averaging about 91 degrees, well above the normal mid-July average of 85 degrees, said Jacqueline …

Indian-Origin Scientist Helps Develop Technique to Identify Stressed Corals

News 18  

Scientists have developed a novel technique to identify heat-stressed corals. Coral reefs provide habitat which support much of the ocean’s biodiversity and anchor the food chains and ecosystems. Threats to the corals brought by the warming ocean waters include coral bleaching and disease, sea-level rise, unsustainable fishing, a more acidic ocean, damage from vessels, marine debris, invasive species and tropical …

News 18  

Half of the Great Barrier Reef’s corals have died over the past 25 years, scientists said Wednesday, warning that climate change is irreversibly destroying the underwater ecosystem. “They’re typically depleted by 80 or 90 percent compared to 25 years ago,” report co-author and James Cook University professor Terry Hughes told AFP. The ‘big mamas’ “A vibrant coral population has millions …
