In the 20th century, global sea level rose faster than at any other time in the past 3,000 years. Its expected to rise even further by 2100, as human-induced climate change intensifies.

Scientists from the University of Sydney have dug deep – literally – to understand how reefs have responded to dramatic changes in the past.. Using fossil reef cores extracted from beneath the Great ...

We refer to this reef as the "proto-Great Barrier Reef". Once a shallow-water barrier reef system, it now exists in a fossilised form at roughly 50 metres water depth and is now the home to deeper ...

Although the Great Barrier Reef survived sea level rise roughly 11,000 years ago, the world was very different back then. Coral reefs faced less stress from human impacts. And ocean temperatures ...

"It had a similar morphology and mix of coral reef communities to the modern Great Barrier Reef. The types of algae and corals, and their growth rates, are comparable.

Learning from the 'proto–Great Barrier Reef' The 15 to 20-meter cores underpinning this research comprise a mix of fossil coral, algae and sediments.

Fossil evidence indicates the Great Barrier Reef survived rapid sea-level rise events 13,000–10,000 years ago by maintaining upward growth rates of 4–6 mm yr −1, within the limits of sea ...

UNESCO’s comments confirm what experts already know: despite substantial money and effort, threats to the Great Barrier Reef aren’t going away.

Unsustainable fishing practices damage the Great Barrier Reef. UNESCO’s draft decision noted progress in eliminating gillnet fishing, which is on track for the target of 2027.

In balanced reef systems with healthy shark populations, COTS outbreaks are typically less severe and less frequent. The Great Barrier Reef Marine Park Authority has documented stronger coral recovery ...

What's happening? As reported by ScienceDaily, the study has unearthed long-term and persistent changes in the biodiversity of the Great Barrier Reef in Australia. This change is linked to increases ...

The Great Barrier Reef ecosystem faces many pressures with some, such as coral bleaching and cyclones, becoming more intense and frequent in recent decades. Extreme heat stress resulted in six mass ...
