Recent acceleration of biomass burning and carbon losses in Alaskan forests and peatlands
Climate change has increased the area affected by forest fires each year in boreal North America 1,2. Increases in burned area and fire frequency are expected to stimulate boreal carbon losses 3–5. However, the impact of wildfires on carbon emissions is also affected by the severity of burning. How...
