As reported by the Guardian, scientists just published a warning that Earth is approaching a point of no return. A new study in the journal One Earth shows multiple climate systems — the Greenland ice sheet, the West Antarctic ice sheet, boreal permafrost, the Amazon rainforest — are all much closer to collapse than previously thought. “Research shows that several Earth system components may be closer to destabilising than once believed,” the researchers urged. “While the exact risk is uncertain, it is clear that current climate commitments are insufficient.”
