Climate Tipping Points: The Point of No Return
Understanding the critical thresholds where small changes trigger irreversible shifts in Earth's climate system
Your Progress
Section 1 of 5What are Climate Tipping Points?
Climate tipping points are critical thresholds where a small change can trigger a large, often irreversible shift in the climate system. Like a ship tipping over the edge of a waterfall, once these points are crossed, the system may not return to its previous state, even if the original forcing is reduced.
These tipping points exist in ice sheets, ocean currents, forests, and other Earth systems. The danger is that they can create feedback loops - changes in one system trigger changes in others, potentially leading to abrupt and potentially catastrophic climate shifts.
Why Tipping Points Matter
Understanding tipping points is crucial because they represent points of no return. Once crossed, they can make it nearly impossible to meet climate goals like limiting warming to 1.5°C or 2°C.

The Danger Zone
We're approaching multiple tipping points simultaneously. Crossing even one could trigger a cascade of changes that make climate goals nearly impossible to achieve.
