Estuaries are one of the most valuable biomes on Earth, and megafires -- like Australia's 2019/20 Black Summer fires -- represent an emerging threat to estuarine and coastal ecosystems, with the extent and proximity of the wildfire influencing the impact on estuaries.

A new paper by dozens of wildfire experts across the nation highlights the need for a more strategic and interdisciplinary approach to pursuing wildfire research and protecting vulnerable communities.

Researchers have developed the first long-term climatology of dry lightning -- lightning which occurs with less than 2.5mm of rainfall -- in central and northern California.

New research linking air pollution data from federal monitors in the Sacramento area of California, including during significant fires, is showing ill effects of pollution exposure among children, a new study suggests.

With fires raging from California to Alaska, the 2022 wildfire season is off to a violent start. It's an ominous sign of what promises to be another record-breaking fire season in the U.S. Roughly 2 million acres burned last month. And major fires are currently scorching Idaho, Utah and California, threatening tens of thousands of Americans' homes and livelihoods. Many of those at risk are lower-income Americans who face canceled homeowners insurance policies and rising premiums, according to new research.

Sea ice and wildfires may be more interconnected than previously thought, according to new research.

In recent years the plumes of smoke crawling upward from Western wildfires have trended taller, with more smoke and aerosols lofted up where they can spread farther and impact air quality over a wider area. The likely cause is climate change, with decreased precipitation and increased aridity in the Western U.S. that intensifies wildfire activity.

Researchers have augmented a physics-based numerical model to investigate and predict areas susceptible to debris flows. This augmented model eventually could be used in an early warning system for people living in high-risk areas, enabling them to evacuate before it's too late. Information from model simulations also could be used to design new infrastructure -- such as diversion bars that deflect fast-moving water away from homes and roads -- for high hazard zones.

A team of investigators devised a new methodology to enable predictions of how plant growth and water quality would change in the wake of wildfires.

New research refining the amount of sunlight absorbed by black carbon in smoke from wildfires will help clear up a long-time weak spot in earth system models, enabling more accurate forecasting of global climate change.

Cats injured in California wildfires are at risk of forming deadly blood clots, according to new research.

The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state's climate-change solution arsenal may be in jeopardy, as new research reports that trees in California's mountain ranges and open spaces are dying from wildfires and other pressures -- and fewer new trees are filling the void.

The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and low-severity fire treatments had the largest impact on reducing the worst effects of the fire, according to a research team.

A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.

New research highlights how the risk of wildfire is rising globally due to climate change -- but also, how human actions and policies can play a critical role in regulating regional impacts. The study shows that anthropogenic climate change is a 'push' factor that enhances the risk of wildfires globally.

New research reveals that wildfires may have been a key contributor to the total collapse of land ecosystems during Earth's worst mass extinction event over 250 million years ago.

Intense heat in the southwestern United States broke records last summer partly because it hit in tandem with an unusually severe drought, finds a new study measuring for the first time how the two extreme weather events dangerously interacted in real time.

A new study examines the context surrounding the fires and offers insight into the historical role of large, high-severity fires -- and the future of wildfires -- west of the Cascades.

Increasing frequency and size of wildfires in the United States over the past several decades affect everything from human life and health to air quality, biodiversity, and land use. The US dairy industry is not exempt from these effects. The Western states, where wildfires are especially prevalent, are home to more than two million dairy cows that produce more than 25% of the nation's milk. A new report examines how dairy cattle in the Western United States may be affected by unique air pollutants from wildfire smoke.

While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of Earth's systems without the influence of humans for hundreds of millions of years.
