New Federal Wildfire Plan Is Ambitious – but the Forest Service Needs More Money and People to Fight the Growing Risks
As foresters who have been working on wildfire and forest restoration issues in the Sierra Nevada for over a quarter of a century, the main lesson we gather from how wildfires have burned is that fuels reduction and forest restoration projects are our best tools for mitigating wildfire impacts amid a changing climate, and not nearly enough of them are being done.

Controlled Burning of Natural Environments Could Help Offset Carbon Emissions
Planting trees and suppressing wildfires do not necessarily maximize the carbon storage of natural ecosystems. A new study has found that prescribed burning can actually lock in or increase carbon in the soils of temperate forests, savannahs and grasslands.

Increasingly Frequent Wildfires Linked to Human-Caused Climate Change: Study
New research strengthens the case that climate change has been the main cause of the growing amount of land in the western U.S. that has been destroyed by large wildfires over the past two decades.

Eight Worst Wildfire Weather Years on Record Happened in the Last Decade
The world’s eight most extreme wildfire weather years have occurred in the last decade. Lower humidity and higher temperatures are driving extreme weather that makes wildfires more frequent and intense.

Human-Caused Climate Change Increases Wildfire Activity
The western United States has experienced a rapid increase of fire weather as the vapor pressure deficit (VPD) increases in the area during the warm season. New research shows that two-thirds (approximately 68 percent) of the increase in VPD is due to human-caused climate change.

Harnessing Science and Technology for Battling Wildfires
Catastrophic wildfires in Europe have become a far too common headline and this year has been no exception as the world once again bore witness to parts of the continent burning. While southern Europe is no stranger to the devastation and loss they leave in their wake, countries in central and northern Europe – areas that were previously not prone to wildfires – are now also experiencing them. Harnessing science and technology, researchers are proving that there is more than one way to fight and respond to fire.

Loss of Fire Lookouts Spurs Questions About Historic Preservation
For decades, fire lookout towers have served as a bridge between the human eye and the surrounding scenery. These former staples of American landscapes are now facing rapid extinction. Decades after their prime, fire lookout towers occupy a precarious position between use and extinction.

Big Fires Demand a Big Response: How 1910’s Big Burn Can Help Us Think Smarter about Fighting Wildfires and Living with Fire
The aftermath of 1910 Big Burn in Northwestern U.S., the Rockies, and parts of British Columbia, led to bold decision-making in forest and fire management techniques and directives. Now, more than a century later, the 21st century’s big burns are a signal that things have gone terribly wrong.

Evaluating Wildfire Hazard
Severe wildfire disasters are often the product of numerous factors coalescing — vegetation, drought, a lack of firefighting resources, and many others. Identifying which factors are the most important is not always a simple task for local leaders assessing their community’s risk for damaging wildfires.

Past Fires May Help in Predicting, Reducing Severity of Future Wildfires in Western U.S.
Researchers analyzed 106 fires that burned in the Klamath Mountains in northwestern California and southwestern Oregon between 2002 and 2018, and concluded that previous fires may hold the key to predicting and reducing the severity of future wildfires in the western United States.

Keeping First Responders Safe by Detecting Cyanide Poisoning after Fires
When first responders rush to a burning building to subdue the fire and save lives, it is not just the flames that are dangerous and potentially lethal, but also toxic fumes like cyanide that are released when certain materials are incinerated. These fumes, mixed with smoke, are so toxic that even in very low quantities may pose more risk than the fire itself. Chemists at DHS S&T have invented a test to indicate possible toxic cyanide exposure at the fire scene.

DOD Imagery Information Aids Wildland Firefighters
With continuing significant fire activity in the western United States this year, the Department of Defense (DoD) is delivering requested personnel, equipment, and facilities, to assist our Federal, State, and local partners fighting wildland fires. One of the tools provided by the DoD is the Firefly system pilot program (Firefly), a capability from the National Geospatial-Intelligence Agency (NGA).

Emberometer Gauges Threat of Wildfire-Spreading Embers
Wildfire fronts spread not only on the ground, but also from above, as the fire launching volleys of glowing embers, also known as firebrands, into the air. These specks of burning debris can glide for up to about 24 miles before landing. They cause up to 90 percent of home and business fires during wildfires.
