Greenland Ice Sheet and climate tipping points
As the ice sheet loses height, its surface encounters warmer air, amplifying melt and potentially committing Greenland to long-term disintegration.
Explore this system in the interactive atlasWhy it matters
What could change
Up to roughly 7 metres of eventual global mean sea-level rise if the ice sheet were lost.
Scientific caution
What remains uncertain
Crossing a threshold would commit long-term change; it would not make the ice sheet disappear suddenly.
Tipping element and tipping point
The tipping element is the part of the climate system described on this page. A tipping point is a critical threshold at which that system could begin moving toward a fundamentally different state. The evidence does not imply a simple, instantaneous planetary switch.

Overshooting the critical threshold for the Greenland ice sheet
Bochow et al. · Nature
Two ice-sheet models place an abrupt-loss threshold between 1.7°C and 2.3°C, while showing that rapid cooling after overshoot can limit loss.Climate tipping point interactions and cascades: a review

Connected tipping elements
These links represent potential interactions, not certain or equally strong causal relationships.
Atlantic Meridional Overturning Circulation
Freshening and warming of the North Atlantic can weaken deep-water formation and the salt-advection feedback that sustains the circulation.
CryosphereWest Antarctic Ice Sheet
Much of the ice rests on bedrock below sea level. Retreat into deeper basins can become self-sustaining once grounding lines destabilize.
MediatorArctic Winter Sea Ice
Summer sea ice is not generally expected to tip under anthropogenic forcing, but winter ice may have multiple states and sea-ice loss can amplify other transitions.
