A new study has revealed that black spruce trees, a key species of trees from the boreal forests, are starting to lose their resilience and capacity to regenerate in the face of increasingly frequent Arctic wildfires caused by climate change. If this trend continues, the Arctic forests might face significant ecological shifts, resulting in a loss of biodiversity and an acceleration in permafrost melting.  In North America’s boreal forests, the soils on which black spruce trees grow consist of highly flammable peat moss and lichens. Although the...
