| Open AccessSubstantial and increasing global losses of timber-producing forest due to wildfires
Wildfires have caused widespread and increasingly severe losses within timber-producing forests in recent decades, according to maps of logging activity and wildfires.

Siberian carbon sink reduced by forest disturbances
Carbon sequestration by Siberian forests has been low over the past decade due to disturbances that have decreased live biomass and increased dead wood, according to passive microwave observations.

Enhanced dust emission following large wildfires due to vegetation disturbance
Enhanced dust emissions are associated with more than half of the global large wildfire events occurring between 2003 and 2020, according to analyses of satellite measurements of aerosol abundance following more than 150,000 global wildfires.

Pyrogenic carbon decomposition critical to resolving fire’s role in the Earth system
Vegetation plays an important role in the aggregate carbon balance of fires, according to a 1901 to 2010 land surface model study that, assuming steady state, shows potentially greater pyrogenic carbon production than legacy losses at global scale, due mostly to grassland adaptations to fire.

Fire effects on the persistence of soil organic matter and long-term carbon storage
Fires reduce plant biomass, which should deplete soil carbon stocks, but a review of recent literature shows that fires also slow decomposition rates and increase soil organic matter stability, offsetting aboveground biomass carbon losses.

Dry corridors opened by fire and low CO2 in Amazonian rainforest during the Last Glacial Maximum
Lower CO2 and more-frequent fires may have supported grassland expansion in the Amazon during the Last Glacial Maximum, according to vegetation modelling using a range of boundary conditions tested against existing pollen records.

Fire enhances forest degradation within forest edge zones in Africa
Fire exacerbates forest degradation in the forest edge zones in Africa, increasing the carbon deficit caused by forest fragmentation, according to analyses of high-resolution satellite data on forest cover and biomass.

Up in smoke
Where there is smoke, there are radiative feedbacks. With wildfires becoming a growing problem in the Anthropocene, we need to better understand the influence of fire on the climate system.

Marine organic carbon burial increased forest fire frequency during Oceanic Anoxic Event 2
A global carbon cycle perturbation during Oceanic Anoxic Event 2 was probably due to elevated oxygen levels leading to a transient increase in wildfire activity, according to a record of plant biomarkers tracking fire frequency in western North America.

The complexities of wildfires
Wildfires are a natural part of many ecosystems, but they can become destructive and less predictable, especially when the system is perturbed. Human activities and climate change lead to interactions with fire dynamics that need our attention.

Burning questions about ecosystems
Cumulative wildfires or prescribed burning produce different outcomes for the vegetation, suggest two long-term analyses of fire-affected ecosystems. Climate change and land management practices are altering how ecosystems function.

Long-term impacts of wildfire and logging on forest soils
Fires and logging alter soil composition and result in a significant reduction of soil nutrients that lasts for decades after the disturbance, suggests an analysis of soil samples across a multi-century sequence in mountain ash forests.

Fire evolution split by continent
Boreal forest fires tend to be more intense and lethal in North America than Eurasia. Differences in tree species composition explain these differences in fire regime, and lead to contrasting feedbacks to climate.

Influence of tree species on continental differences in boreal fires and climate feedbacks
Boreal forest wildfires in North America are more intense and destructive than in Eurasia. Differences in species-level adaptations to fire are primary drivers of these differences in fire regimes.

Global vulnerability of peatlands to fire and carbon loss
The amount of carbon stored in peats exceeds that stored in vegetation. A synthesis of the literature suggests that smouldering fires in peatlands could become more common as the climate warms, and release old carbon to the air.

Extinction promoted fire
The extinction of megafauna in Australia roughly coincided with shifts in vegetation and fire regimes. Sediment geochemistry shows that the vegetation shift followed the extinction, indicating that the loss of browsers promoted fire and altered plant composition.
