Section 3 of 5Detecting Tipping Points Before They Happen
Early warning signals are measurable changes in system behavior that indicate a tipping point is approaching. These signals appear before the actual transition, giving us a chance to prevent irreversible changes. Scientists use various methods to detect these signals across different Earth systems.
The Challenge
Many tipping points have unknown thresholds, and early warning signals can be subtle. However, combining multiple detection methods increases our ability to identify approaching transitions.
