Natural Nitrogen Emissions Are Rising in California
Wildfires and soil microbes are releasing more nitrogen oxides in California as the climate gets warmer and drier.
How Wildfires and Weather Affect Portugal’s Public Health
Researchers dug into data to examine the effects of wildfires, pollutants, and meteorological factors on mortality and cardiovascular health in the Iberian country.
Wet Conditions Delay Wildfire Detection
When accompanied by a considerable amount of rainfall, ignition of wildfire by lightning over forested land may not be detected until days later.
Lightning-Caused Wildfires are 80 Percent More Likely Under Dry Vegetation
Mimicking a randomized control trial of wildfires, scientists use satellites to uncover the key role of vegetation dryness in wildfire risk, aiding wildfire management and preparedness in California.
Where Does Fire Retardant Fall in a Forest? Ask a Satellite
Knowing where fire retardant lands once it’s dropped from a plane is hard to pin down. A new remote sensing approach offers clues.
As Wildfires Grow, So Could Methane Emissions
Wildfires that wreaked havoc on California in 2020 filled the atmosphere with a potent greenhouse gas.
Using Cave Formations to Investigate Ancient Wildfires
From sediment cores to speleothems, environmental archives are helping us to understand the history of wildfires.
Climate Change, Megafires Crush Forest Regeneration
High-intensity fires in western states kill mature trees and their seeds while warmer, drier conditions stress seedlings. But forest managers can still intervene to change this trajectory.
Wildfire Smoke Destroys Ozone
Smoke aerosols from large wildfires are the perfect reaction surface for chlorine chemicals, speeding their transformation from ozone-friendly forms to reactive ones.
