West African Monsoon and climate tipping points
Land-ocean temperature contrasts and feedbacks may reorganize Sahel rainfall, but models disagree on whether change would be abrupt and in which direction.

What could change
Major implications for agriculture, water security, ecosystems, and livelihoods across the Sahel and Gulf of Guinea.
Scientific caution
What remains uncertain
The historical ‘Green Sahara’ transition demonstrates nonlinearity, but its relevance to near-future anthropogenic change is unsettled.
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.

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.
MediatorEl Niño–Southern Oscillation
ENSO is a powerful source of global climate variability that can transmit and intensify stress across rainforests, monsoons, coral reefs, and polar ice.
