BERLIN, Sept 13 (Reuters) - The Earth's life-support systems are facing greater risks and uncertainties than ever before, with most major safety limits already crossed as a result of planet-wide human interventions, according to a scientific study released on Wednesday. The authors said crossing the boundaries did not represent a tipping point where human civilisation would just crash, but could bring irreversible shifts in the Earth's support systems. "We can think of Earth as a human body, and the planetary boundaries as blood pressure. Over 120/80 does not indicate a certain heart attack but it does raise the risk," Richardson said. "It is a complete failure ...and it's a large risk... We're still following a pathway that takes us unequivocally to disaster."

The scientists analyzed nine interlinked “planetary boundaries,” which they define as thresholds the world needs to stay within to ensure a stable, livable planet. A ‘stark warning’Crossing planetary boundaries does not mean the world has reached a disastrous tipping point. As humanity crosses planetary boundaries, our “bank balance” is going down, she said. The significance of the planetary boundaries model is that it doesn’t analyze climate and biodiversity in isolation, the report authors said. This report is the third update on the planetary boundaries framework.
