Coral around the world has been dying at unprecedented rates, largely the result of warming ocean waters due to climate change. Now, the International Coral Reef Society’s scientists have published what they call the “Pledge for Coral Reefs,” a list of 12 actions everyone can take to help protect coral and coral reefs.

“This is an educational tool to remind people that, ‘Wow, when I purchase products with single-use plastic, that affects coral reefs. When I don’t eat sustainably, that affects coral reefs. If I don’t vote, that affects coral reefs. So many environmental and climate change related issues impact coral reefs,” said Andréa Grottoli, professor of earth sciences at The Ohio State University and president of the International Coral Reef Society.

“Each of th...

On a 24-hour boat trip off the coast of Western Australia, Dr. Taryn Foster was seeking out a coral reef treasure known as Scott Reef. It was a familiar place for her, as the research associate at the California Academy of Sciences had gone on dives and conducted coral surveys there as part of her postdoctoral work studying coral.

“There’s no tourists out there,” Foster said. “It’s as untouched as you can get these days.”

But Foster found the condition of Scott Reef had changed wildly from years past. She was about to dive into the coral reefs during the worlds’ 2016 mass bleaching event — one of the longest and most severe coral bleaching events on record.

“In a way, it’s actually quite beautiful...

A British family is leaving their comfortable life in London in order to pursue something more. The Seath family, including Karolina, Barry and their two children, are about to move to an island you probably never heard of in a bid to help replenish and revitalize the area’s coral reef, which have been ravaged by the rising sea temperatures off the coast of Africa’s smallest island.

The island in the Seychelles, measuring just 400 metres long by 300 metres wide, will play host to the family’s land-based coral farm, which will only be the second of its kind in the entire world — the other being on Australia’s Great Barrier Reef.

“We are just a normal husband, wife, and two kids, living the sort of life that most others do… but we felt the need to make a positive change for oursel...

UNESCO should declare the Red Sea’s 4000km of coral reef a Marine World Heritage Site and take additional measures critical for the reef’s survival, urges an international group of researchers led by Karine Kleinhaus, MD, of Stony Brook’s School of Marine and Atmospheric Sciences (SoMAS).

Their article, “Science, Diplomacy, and the Red Sea’s Unique Coral Reef: It’s Time for Action,” appears in Frontiers in Marine Science. Kleinhaus and co-authors argue that while rapid ocean warming due to climate change is predicted to decimate 70 to 90 percent of the world’s coral reefs by mid-century, the coral reef ecosystem in the Red Sea’s Gulf of Aqaba is strikingly resilient to rising sea temperatures.

Corals in the Gulf of Aqaba, at the northernmost portion of the Red Sea, wi...

Reef corals in equatorial regions are going to start moving toward the poles as climate change takes hold, scientists have said. By analyzing the ranges of reefs from the fossil record, researchers are able to build a picture of how these systems respond to climate change—and then project how they might respond under future global warming.

Findings show that, under two climate change scenarios set out by the Intergovernmental Panel on Climate Change (IPCC), reefs are likely to expand their poleward range—in both the Northern and Southern hemispheres—and decline in the regions they currently occupy. This will mean a fundamental change to the locations of reef corals in the future.

The study, published in the journal Royal Society Open Science, examines the fossil record for ho...

Beneath the crystal-clear waters of the Indian Ocean island nation of the Seychelles, a fight is growing to save the coral reefs that shelter a range of creatures, from tiny invertebrates to the sprawling octopus, from climate change.

The fragile reefs act both as a protective barrier for coastlines and an attraction for the tourists who keep the country’s economy going. But the reefs are also one of the first victims of rising ocean temperatures.

The Seychelles in some areas lost up to 90 percent of its coral reefs in 1998 in an environmental event known as bleaching, where coral in warming waters expel the colorful algae that live within their skeletons and, without their nutrients, starve...

When coral reefs come in contact with plastic trash in the ocean, their risk of becoming diseased skyrockets, said an international study. Researchers examined 1,20,000 corals on 159 reefs from Indonesia, Australia, Myanmar and Thailand for the study in journal science we found the chance of disease increased from 4% to 89% when corals were in contact with plastic.

Scientists are still trying to figure out why plastics are so dangerous for coral, which cover about 0.2% of ocean floor but provide habitat for million species of young fish.

As if the devastation in Texas wasn’t enough, Hurricane Harvey’s aftermath has also brought a real threat to the Gulf of Mexico. A massive freshwater plume has poured runoff into the Gulf, temporarily altering the surrounding water’s salinity – and threatening coral reefs.

Harvey dumped some 20 trillion gallons of rain on the Lone Star State, and that record rainfall had to go somewhere. That somewhere is the Gulf of Mexico. Scientists estimate an incredible 13 trillion gallons entered the Gulf in the days immediately following the storm.

The possible negative effects of that much freshwater entering the saltwater ecosystem became apparent on September 28...

Did you know coral reefs pump more than $3.4 billion into the U.S. economy each year? And that’s a conservative estimate! Healthy coral reef ecosystems do everything from supporting millions of jobs to protecting lives and coastal infrastructure. Despite all they do for us, our coral reef ecosystems are threatened. Climate change, pollution from the land, and harmful fishing practices top the list of threats. Fortunately, it’s not too late to protect these resources. Watch our fast-draw video to learn more.
