Thanks to the dire condition of the Earth's coral reefs, the planet has now reached its first tipping point for human-caused climate change, according to a new report by scientists in Europe.
The second Global Tipping Points Report, released Oct. 13, said warm-water coral reefs – on which nearly 1 billion people and a quarter of all marine life depend – are "passing their tipping point."
According to the report, widespread coral dieback is taking place and – unless global warming is reversed – extensive reefs as we know them will be lost, although small refuges may survive and must be protected.
What is a 'tipping point'?
A “tipping point” occurs when a small change tips a system into a new state, causing significant and long-term transformation. With the climate, these points of no return are specific moments when the planet has warmed so much that certain effects become irreversible.
