Boreal Forest and climate tipping points
Heat, drought, insects, and fire may accelerate southern forest loss faster than tree cover can expand into the tundra to the north.
Explore this system in the interactive atlasWhy it matters
What could change
Biome contraction, ecological reorganization, carbon loss, and altered surface reflectivity and hydrology.
Scientific caution
What remains uncertain
A continent-wide abrupt threshold is less established than interacting regional transitions and disturbance feedbacks.
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.

Northern expansion is not compensating for southern range loss in North American boreal forests
Rotbarth et al. · Nature Communications
Satellite observations show that slow northern gains did not offset faster southern tree-cover losses from 2000 to 2019.Exceeding 1.5°C global warming could trigger multiple climate tipping points
Armstrong McKay et al. · Science
Synthesizes threshold ranges, transition timescales, and impacts for sixteen proposed tipping elements.Possible interactions
Connected tipping elements
These links represent potential interactions, not certain or equally strong causal relationships.
Northern Permafrost
Ice-rich ground can collapse abruptly into thermokarst landscapes, while thaw exposes ancient carbon to decomposition and greenhouse-gas release.
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.
