Lathering up with sunscreen may protect against cancer — killing coral reefs worldwide, Science Daily 910-20-2015)
That’s the conclusion of a team of international scientists, which includes University of Central Florida professor and diving enthusiast John Fauth. The researchers found that oxybenzone, a common UV-filtering compound, is in high concentrations in the waters around the more popular coral reefs in Hawaii, and the Caribbean. The chemical not only kills the coral, it causes DNA damage in adults and deforms the DNA in coral in the larval stage, making it unlikely they can develop properly. The highest concentrations of oxybenzone were found in reefs most popular with tourists.

Thirsty mangroves cause unprecedented dieback; Australia’s northern coast

Excerpts;

A James Cook University scientist has discovered why there was an unprecedented dieback of mangroves in the Gulf of Carpentaria in early 2016 – the plants died of thirst.

Dr Norman Duke, leader of JCU’s Mangrove Research hub, headed an investigation into the massive mangrove dieback. The findings were published in the Journal of Marine and Freshwater Research (Tuesday 14 March).

The scientists used aerial observations and satellite mapping data of the area dating back to 1972, combined with weather and climate records.

Dr Duke said they found three factors came together to produce the unprecedented dieback of 7400 hectares of mangroves, which stretched for 1000 kilometres along the Gulf coast…

Corals Die as Global Warming Collides with Local Weather in the South China Sea

Excerpts;

In the South China Sea, a 2°C rise in the sea surface temperature in June 2015 was amplified to produce a 6°C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community according to a study published in Scientific Reports this week.

Wind and waves churn the sea, flushing shallow-water coral reefs with seawater from the open ocean to help them stay cool. But according to new research from the Woods Hole Oceanographic Institution (WHOI), when the weather turns still and these natural cooling mechanisms subside, just a few degrees of ocean warming can prove lethal to the corals that live there…

Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study.

Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone – a low-oxygen area that snuffs out marine life – rather than by ocean warming or acidification…
