Drivers and Impacts of the Record-Breaking 2023 Wildfire Season in Canada
The 2023 wildfire season in Canada was unprecedented in its scale and intensity, spanning from mid-April to late October and across much of the forested regions of Canada. Here, we summarize the main causes and impacts of this exceptional season.
A Wildfire Progression Simulation and Risk-Rating Methodology for Power Grid Infrastructure
As the frequency and intensity of power line-induced wildfires increase due to climate-, human- , and infrastructure-related risk drivers, maintaining power system resilience and reducing environmental impacts become increasingly crucial.
Biogeographic patterns of daily wildfire spread and extremes across North America
Introduction: Climate change is predicted to increase the frequency of extreme single-day fire spread events, with major ecological and social implications.
Carbon emissions from the 2023 Canadian wildfires
The 2023 Canadian forest fires have been extreme in scale and intensity with more than seven times the average annual area burned compared to the previous four decades. Here, we quantify the carbon emissions from these fires from May to September 2023 on the basis of inverse modelling of satellite carbon monoxide observations.
Trees have similar growth responses to first-entry fires and reburns following long-term fire exclusion
Managing fire ignitions for resource benefit decreases fuel loads and reduces the risk of high-severity fire in fire-suppressed dry conifer forests. However, the reintroduction of low-severity wildfire can injure trees, which may decrease their growth after fire.
Untrammeling the wilderness: restoring natural conditions through the return of human-ignited fire
Historical and contemporary policies and practices, including the suppression of lightning-ignited fires and the removal of intentional fires ignited by Indigenous peoples, have resulted in over a century of fire exclusion across many of the USA’s landscapes.
A fire-use decision model to improve the United States’ wildfire management and support climate change adaptation
The US faces multiple challenges in facilitating the safe, effective, and proactive use of fire as a landscape management tool. This intentional fire use exposes deeply ingrained communication challenges and distinct but overlapping strategies of prescribed fire, cultural burning, and managed wildfire.
Rare and highly destructive wildfires drive human migration in the U.S.
The scale of wildfire impacts to the built environment is growing and will likely continue under rising average global temperatures. We investigate whether and at what destruction threshold wildfires have influenced human mobility patterns by examining the migration effects of the most destructive wildfires in the contiguous U.S. between 1999 and 2020.
From flexibility to feasibility: identifying the policy conditions that support the management of wildfire for objectives other than full suppression
Background. Intentional management of naturally ignited wildfires has emerged as a valuable tool for addressing the social and ecological consequences of a century of fire exclusion in policy and practice. Policy in the United States now allows wildfires to be managed for suppression and other than full suppression (OTFS) objectives simultaneously, giving flexibility to local decision makers.
