Coral bleaching on the Great Barrier Reef last year was even worse than expected, while the full impact of the most recent event is yet to be determined.

French oil and gas company Total and other energy majors should abandon plans to drill close to the mouth of Brazil's Amazon because of potential risks to the ecosystem of the area, environmental c

Lamu fishermen on Tuesday told a five-judge bench that the ongoing construction of the multibillion-shilling Lamu Port-South Sudan-Ethiopia Transport (Lapsset) corridor had violated their rights to

Coastal marine food webs could be in danger of collapse as a result of rising carbon dioxide levels, according to our new research.

This time last year, scientists announced the discovery of a reef system at the mouth of the Amazon River — and right from the beginning, they began issuing warnings about companies’ plans to drill

Intensifying climate change remains the biggest threat to coral reefs around the world, with rising sea surface temperatures driving widespread bleaching events, according to the Climate Council’s latest report.

Degradation of coastal water quality in the form of low dissolved oxygen levels (hypoxia) can harm biodiversity, ecosystem function, and human wellbeing. Extreme hypoxic conditions along the coast, leading to what are often referred to as “dead zones,” are known primarily from temperate regions. However, little is known about the potential threat of hypoxia in the tropics, even though the known risk factors, including eutrophication and elevated temperatures, are common.

During 2015–2016, record temperatures triggered a pan-tropical episode of coral bleaching, the third global-scale event since mass bleaching was first documented in the 1980s. Here we examine how and why the severity of recurrent major bleaching events has varied at multiple scales, using aerial and underwater surveys of Australian reefs combined with satellite-derived sea surface temperatures. The distinctive geographic footprints of recurrent bleaching on the Great Barrier Reef in 1998, 2002 and 2016 were determined by the spatial pattern of sea temperatures in each year.

Tropical cyclones and sea level rise cause major problems including beach erosion and damage to infrastructure in coastal areas. Inexpensive but effective plans for coastal protection will be needed by small island nations and developing countries. Natural breakwater formed by reefs is more cost-effective in coastal protection than the construction of artificial defenses. It provides a habitat for marine organisms and societal benefits including marine products, tourism, and education.

There were startling colours here just a year ago, a dazzling array of life beneath the waves. Now this Maldivian reef is dead, killed by the stress of rising ocean temperatures.
