Fungi have evolved unique strategies to digest charcoal and other pollutants, including gene duplication and horizontal gene transfer. These discoveries could lead to new methods for cleaning up contaminated environments.
A new study published in Environmental Science & Technology found that exposure to wildfire smoke during the third trimester may raise the risk of autism diagnoses in children. Mothers who were exposed to more than 10 days of wildfire smoke had a 23% higher risk of their child being diagnosed with autism by age 5.
Researchers at Harvard John A. Paulson School of Engineering and Applied Sciences quantify the role of climate change in wildfires and air quality, finding that 60-82% of total burned area in western US forests is directly attributable to warming temperatures and drier conditions caused by climate change.
A new computer model, GeoFlame VISION, uses AI and satellite imagery to produce a dynamic wildfire risk map for the entire US. The model shows that California's eastern, southwestern, and northwestern parts are at high risk due to Santa Ana winds.
Human-driven climate change makes wildfires in parts of South America and Southern California much larger and more destructive. Climate models warn that severe heatwaves and droughts will make extreme wildfires more frequent and intense worldwide.
A recent study found that UK heatwaves have led to unseasonable drying of vegetation, bypassing natural ecological processes that limit the spread of wildfires. The extreme heat conditions increased the risk of wildfire incidents, with a 500% increase in 999 calls and 14 major incidents during the 2022 heatwave.
The NSF-funded project aims to understand and reduce grassland fire risk by studying fuel variability and response to prescribed fire. The team will develop mapping tools to estimate wildfire risk, enabling land managers to plan and reduce the risk of devastating grassland fires.
