Earth 'decades away' from tipping point which triggers climate change apocalypse
Earth may only be decades away from a climatic tipping point that triggers runaway global warming and threatens the future of humanity, scientists have warned. The threshold will be reached when average global temperatures are only around 2C higher than they were in pre-industrial times, new research suggests. They are already 1C higher and rising. Feedback mechanisms acting ‘like a row of dominoes’ will then spin the world into a ‘Hothouse Earth’ state of uncontrollable climate change.
