Anthropogenic climate change may result in novel disturbances to Arctic tundra ecosystems. Understanding the natural variability of tundra-fire regimes and their linkages to climate is essential in evaluating whether tundra burning has increased in recent years. Historical observations and charcoal records from lake sediments reveal a wide range of fire regimes in Arctic tundra, with fire-return intervals varying from decades to millennia. Analysis of historical data shows strong climate–fire… Expand

Figures from this paper

Arctic and boreal paleofire records reveal drivers of fire activity and departures from Holocene variability.
The lack of widespread, prolonged fire synchrony suggests regional heterogeneity limited simultaneous fire-regime change across the authors' study areas during the Holocene, which implies broad-scale resilience of the boreal forest to extensive fire activity, but does not preclude novel responses to 21-century changes.

Sedimentary charcoal proxy records of fire in Alaskan tundra ecosystems
Abstract Extensive burning of Arctic tundra landscapes in recent years has contradicted the conventional view that fire is a rare, spatially limited disturbance in tundra. These fires have beenExpand
Climatic thresholds shape northern high‐latitude fire regimes and imply vulnerability to future climate change
Boreal forests and arctic tundra cover 33% of global land area and store an estimated 50% of total soil carbon. Because wildfire is a key driver of terrestrial carbon cycling, increasing fireExpand
Long-term effects of fire on Arctic tundra vegetation in Western Siberia
Summary Wildfires are a naturally rare phenomenon in subarctic tundra ecosystems. Climate change triggers feedback loops that probably increase fire frequency and extent in those regions. Fire canExpand
Arctic landscape dynamics: modern processes and pleistocene legacies
The Arctic Cryosphere (AC) is sensitive to rapid climate changes. The response of glaciers, sea ice, and permafrost-influenced landscapes to warming is complicated by polar amplification of globalExpand
Summer warming explains widespread but not uniform greening in the Arctic tundra biome
The hypothesis that summer warming stimulated plant productivity across much, but not all, of the Arctic tundra biome during recent decades is supported. Expand
Temperature-controlled tundra fire severity and frequency during the last millennium in the Yukon-Kuskokwim Delta, Alaska
Wildfire is an important disturbance to Arctic tundra ecosystems. In the coming decades, tundra fire frequency, intensity, and extent are projected to increase because of anthropogenic climateExpand
The morphology of experimentally produced charcoal distinguishes fuel types in the Arctic tundra
Wildfires in the Arctic tundra have become increasingly frequent in recent years and have important implications for tundra ecosystems and for the global carbon cycle. Lake sediment–based records areExpand
Divergent shrub-cover responses driven by climate, wildfire, and permafrost interactions in Arctic tundra ecosystems.
Estimation of shrub-cover change in 114 study sites across four burned and unburned upland and lowland tundra ecosystems in northern Alaska offers new insights into the land-atmosphere interactions as climate warming and burning intensify in high latitudes. Expand
Circumpolar spatio-temporal patterns and contributing climatic factors of wildfire activity in the Arctic tundra from 2001–2015
Recent years have seen an increased frequency of wildfire events in different parts of Arctic tundra ecosystems. Contemporary studies have largely attributed these wildfire events to the Arctic'sExpand


Variability of tundra fire regimes in Arctic Alaska: millennial‐scale patterns and ecological implications
Tundra fires have important ecological impacts on vegetation, wildlife, permafrost, and carbon cycling, but the pattern and controls of historic tundra fire regimes are poorly understood. We useExpand
The footprint of Alaskan tundra fires during the past half-century: implications for surface properties and radiative forcing
Recent large and frequent fires above the Alaskan arctic circle have forced a reassessment of the ecological and climatological importance of fire in arctic tundra ecosystems. Here we provide aExpand
Spatiotemporal patterns of tundra fires: late-Quaternary charcoal records from Alaska
Abstract. Anthropogenic climate change has altered many ecosystem processes in the Arctic tundra and may have resulted in unprecedented fire activity. Evaluating the significance of recent firesExpand
Tundra burning in Alaska: Linkages to climatic change and sea ice retreat
[1] Recent climatic warming has resulted in pronounced environmental changes in the Arctic, including shrub cover expansion and sea ice shrinkage. These changes foreshadow more dramatic impacts thatExpand
Frequent Fires in Ancient Shrub Tundra: Implications of Paleorecords for Arctic Environmental Change
Paleoecological data suggest that greater fire activity will likely accompany temperature-related increases in shrub-dominated tundra predicted for the 21st century and beyond, which will have broad impacts on physical and biological systems as well as on land-atmosphere interactions in the Arctic.

Climate-Driven Effects of Fire on Winter Habitat for Caribou in the Alaskan-Yukon Arctic
It is projected that the Porcupine caribou herd could be expected to experience a greater reduction in lichen-producing winter habitats than the Central Arctic herd that wintered primarily in the arctic tundra, given the more likely climate trajectory. Expand
Carbon loss from an unprecedented Arctic tundra wildfire
The magnitude of ecosystem C lost by fire, relative to both ecosystem and biome-scale fluxes, demonstrates that a climate-driven increase in tundra fire disturbance may represent a positive feedback, potentially offsetting Arctic greening and influencing the net C balance of the tundRA biome.

Simulating the effects of climate change on fire regimes in Arctic biomes: implications for caribou and moose habitat
Wildfire is the primary ecological driver of succession in the boreal forest and may become increasingly important within tundra ecosystems as the Arctic warms. Migratory barren-ground caribouExpand

This paper reviews the current status of using remote sensing and process-based modeling approaches to assess the contemporary and future circumpolar carbon balance of Arctic tundra, including the exchange of both carbon dioxide and methane with the atmosphere, and indicates that ArcticTundra will be a small sink for carbon over the next century.

Identification of unrecognized tundra fire events on the north slope of Alaska
[1] Characteristics of the natural fire regime are poorly resolved in the Arctic, even though fire may play an important role cycling carbon stored in tundra vegetation and soils to the atmosphere.Expand
