What is killing the Great Barrier Reef?

What caused the bleaching of the Great Barrier Reef?
Bleaching is caused by global warming, but this is the reef’s first bleaching event during a La Niña weather pattern, which is associated with cooler Pacific Ocean temperatures, the Great Barrier Reef Marine Authority said in its annual report released late Tuesday that found 91% of the areas surveyed were affected.
What has happened to the Great Barrier Reef?
The Reef is highly vulnerable. In the past three decades, it has lost half its coral cover, pollution has caused deadly starfish outbreaks, and global warming has produced horrific coral bleaching. Coastal development also looms as a major threat.
What are the four major threats to the Great Barrier Reef Marine Park?
Climate change is the greatest threat to the Great Barrier Reef, threatening its very existence.
- Coral Bleaching. The Reef has suffered three mass coral bleaching events in just five years due to heat stress caused by climate change.
- Water quality.
- Crown of Thorns Starfish.
- Coastal development.
How long until the Great Barrier Reef dies?
The Great Barrier Reef is at a critical tipping point and could disappear by 2050.
Is the Great Barrier Reef still alive?

How much of the Great Barrier Reef is bleached 2020?
90%

Is the Great Barrier Reef doomed?
