Aerosol pollution, greenhouse gases must be reduced simultaneously to keep forest fires in check      (via sciencedaily.com)     Original source 

If we want cleaner air, fewer forest fires, and less severe climate change, a new study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.

How wildfires change soil chemistry      (via sciencedaily.com)     Original source 

Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.

Improved wildfire smoke model identifies areas for public health intervention      (via sciencedaily.com)     Original source 

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.

Wildfires in wet African forests have doubled in recent decades      (via sciencedaily.com)     Original source 

Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.

Anthropologist documents how women and shepherds historically reduced wildfire risk in Central Italy      (via sciencedaily.com)     Original source 

Fire management lessons from the past could help to improve resilience as the Mediterranean faces increased fire risk from climate change. How traditional land management practices once greatly reduced fuel for wildfires, and how these practices were forgotten, in part due to historical politics of classism and sexism.

CO2 worsens wildfires by helping plants grow      (via sciencedaily.com)     Original source 

By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.

Fires pose growing worldwide threat to wildland-urban interface      (via sciencedaily.com)     Original source 

Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.

Unintended consequences of fire suppression      (via sciencedaily.com)     Original source 

A new study reveals how fire suppression ensures that wildfires will burn under extreme conditions at high severity, exacerbating the impacts of climate change and fuel accumulation.

2020 extreme weather event that brought fires and snow to western US      (via sciencedaily.com)     Original source 

The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event.

Cooler, wetter parts of Pacific Northwest likely to see more fires, new simulations predict      (via sciencedaily.com)     Original source 

Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier.

Discovering the physics behind 300-year-old firefighting methods      (via sciencedaily.com)     Original source 

Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber's Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.

Targeted household cleaning can reduce toxic chemicals post-wildfire      (via sciencedaily.com)     Original source 

Wildfires create compounds called polycyclic aromatic hydrocarbons (PAHs), which are formed in the combustion process at high temperatures. These compounds are highly toxic. New research examined how long harmful chemicals found in wildfire smoke can persist and the most effective ways to remove them with everyday household cleaners.
