Arctic forests face new survival threat as warming shifts stress from hunger to thirst

A study of Siberian larch forests reveals that climate warming has fundamentally altered what kills these trees—switching from nitrogen starvation to drought stress as permafrost thaws. For industries dependent on boreal forests and carbon markets betting on Arctic reforestation, this shift signals unpredictable forest die-off patterns and calls into question adaptation strategies built on older climate assumptions.
