"The earth has reached its first catastrophic tipping point linked to greenhouse gas emissions, with warm water coral reefs now facing a long-term decline and risking the livelihoods of hundreds of millions of people, according to a new report.
The report from scientists and conservationists warns the world is also “on the brink” of reaching other tipping points, including the dieback of the Amazon, the collapse of major ocean currents and the loss of ice sheets.
But some experts have questioned the report’s claims about the fate of coral reefs, with one saying while they are in decline there is evidence they could remain viable at higher temperatures than suggested.
Tipping points are recognised by scientists as moments when a major ecosystem reaches a point where severe degradation is inevitable.
The world’s coral reefs are home to about a quarter of all marine species but are considered one of the most vulnerable systems to global heating."
