World’s biggest coral survey confirms sharp decline in Great Barrier Reef after heatwave

The latest report from Australia’s tropical marine research agency shows hard corals on the Great Barrier Reef have been hit hard by an extreme marine heatwave.

High coral cover amid intense heatwaves and bleaching? Here’s how both can be true on the Great Barrier Reef

One of the most serious marine heatwaves on record hit the Great Barrier Reef last summer. Now a new report shows that coral cover was high before the impacts of cyclones and mass bleaching.

O branqueamento dos corais causado pelo aquecimento dos oceanos exige uma resposta global

O primeiro evento de branqueamento global ocorreu em 1998 e o quarto está em andamento. Até que reduzamos as emissões que provocam o aquecimento global, a pressão sobre os recifes de coral só vai aumentar

Global coral bleaching caused by global warming demands a global response

The first global bleaching event was in 1998 and the fourth is now under way. Until we curb the emissions driving global warming, the pressure on coral reefs will continue to increase.
