Briefings

A global assessment indicates that every shallow-water coral reef ecosystem in Australia faces an extremely high risk of collapse by 2075, primarily driven by projected ocean warming. This finding highlights a critical window for intervention, as reefs are already under significant stress from climate change impacts.

Key points

• Every shallow-water coral reef ecosystem in Australia faces an extremely high risk of collapse by 2075.
• The primary driver of this risk is projected ocean warming.

Context

This assessment represents a global evaluation of coral reef health across Australia, identifying 2075 as the critical deadline for potential ecosystem failure due to thermal stress.

Limitations

The evidence covers only shallow-water ecosystems in Australia and relies on projected warming scenarios rather than historical data or specific local measurements.
