The planet is said to be facing a “global cascade of tipping points” that could heavily disrupt human societies and ecosystems unless nations slash their greenhouse gas emissions, according to an article in “Nature”.
The authors identified several “large-scale discontinuities” in the climate system that may be underway and which could trigger further warming.
The scientists said, "if damaging tipping cascades can occur and a global tipping point cannot be ruled out, then this is an existential threat to civilisation.”
