Point of no return: a hellish ‘hothouse Earth’ getting closer, scientists say

Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware The world is closer than thought to a “point of no return” after which runaway global heating cannot be stopped, scientists have said.Continued global heating could trigger climate tipping points, leading to a cascade of further tipping points and feedback loops, they said. This would lock the world into a new and hellish “hothouse Earth” climate far worse than the 2-3C temperature rise the world . The climate would also be very different to the benign conditions of the past 11,000 years, during which the whole of human civilisation developed.
