Excerpts;

The government agency that manages Australia’s Great Barrier Reef has downgraded its outlook for the corals’ condition from “poor” to “very poor” due to warming oceans.

The Great Barrier Reef Marine Park Authority’s condition report, which is updated every five years, is the latest bad news for the 133,360-square-mile colorful coral network off the northeast Australian coast as climate change and coral bleaching take their toll…

Excerpts;

New guidelines drafted by a consortium of concerned experts could enable corals to adapt to changing environments and help restore declining populations in the Caribbean. The guidelines provide a definitive plan for collecting, raising, and replanting corals that maximizes their potential for adaptation…

Beyond Preservation: The Coral Restoration Foundation Bonaire; By Andrew Jalbert (08-01-2018)
When avid scuba diver and famed Jurassic Park author Michael Crichton first visited Bonaire decades ago, he eloquently described the underwater environment as, “a world of riotous, outrageous color.” Years later, Bonaire has seen some changes but his assessment still largely rings true…

Abu Dhabi is replanting mangroves in the fight against climate change

uae-coast-nasa
UAE Coast. The area around Abu Dhabi is rich in mangroves—trees and shrubs able to grow in salty soil and water—that help prevent coastal erosion. Although mangrove forests typically occur in tropical and subtropical environments, the summertime temperatures along the UAE coast (often exceeding 35°C, or 95°F) pose challenges to mangrove survival. Mangrove forests here have grown in recent decades, according to the UAE government, thanks to large-scale re-forestation programs.

Excerpts;

The coastal city of Abu Dhabi is one of the most vulnerable places in the world to the impacts of climate change. It’s threatened by rising sea levels and researchers say it could be too hot to live in by the end of this century if global warming trends continue.

But trees are helping the city fight the climate crisis. Mangroves…

Thirty years of unique data reveal what’s really killing coral reefs

Excerpts;

Coral bleaching is not just due to a warming planet, but also a planet that is simultaneously being enriched with reactive nitrogen from sources like improperly treated sewage, and fertilizers.

Nitrogen loading from the Florida Keys and greater Everglades ecosystem caused by humans is the primary driver of coral reef degradation in Looe Key. These coral reefs were dying off long before they were impacted by rising water temperatures. Elevated nitrogen levels cause phosphorus starvation in corals, reducing their temperature threshold for bleaching…

Excerpts;

The health of coral reefs can be impacted as much by the diversity of fish that graze on them as by the amount of fish that do so, according to a new study. In the paper, the researchers untangle and unveil the powerful effects that biodiversity has on Caribbean coral reefs…
