Wildfire modeling helps predict fires in Colombia

A new wildfire model helps predict where and when wildfires will start in the Aburrá Valley of Colombia. This research, presented earlier this month at the 2019 American Geophysical Union Fall Meeting in San Francisco, is helping local cities avoid the devastating environmental and health impacts of fires.

Wildfire residue may contribute to climate change

Wildfires leave behind large swathes of blackened earth when they raze a landscape. That charred material contains a host of molecules that could continue to release carbon dioxide into the atmosphere days and weeks after the fire has gone out, according to new research.

Climate change may push Santa Ana fire season into winter months

Climate models predict a narrowing of the Santa Ana season in tandem with the wet season in Southern California over the next century, which could leave vegetation dry and fire-prone as winds peak in December and January, according to a new study.

AGU Applauds the Fourth National Climate Assessment

In 1990, President Ronald Reagan initiated the U.S. Global Change Research Program, and Congress mandated that a report be released at least every four years outlining what climate change – past, present, and future – means for the United States. In the decades since, four of  the National Climate Assessments have been released and AGU members have played a role in each one as authors and as contributors of their …

Robust Investment in Natural Hazards Research is Essential to Our Safety and Security

Tomorrow, 13 October, is International Day for Disaster Reduction, created by the United Nations in 1989 to promote risk-awareness and natural disaster reduction. Now, as then, the need for proactive action is clear to help save lives and reduce devastating economic losses. Since 13 October last year, the United States has seen flooding from Tropical Storm Lane in Hawaii and Hurricane Florence in North and South Carolina, the latter causing …

Smoke from wildfires has cooling effect on water temperatures

Smoke generated by wildfires can cool river and stream water temperatures by reducing solar radiation and cooling air temperatures, according to a new study in California’s Klamath River Basin. A new study published in Water Resources Research, a journal of the American Geophysical Union, suggests smoke-induced cooling has the potential to benefit aquatic species that require cool water to survive because high summer water temperatures are a major factor contributing to population declines, and wildfires are more likely to occur during the warmest and driest time of year.

Seismometer readings could offer debris flow early warning

Instruments designed to record earthquakes revealed information about debris-flow speed, the width of the flow and the size of boulders carried by the January 2017 mudslide in Montecito, California, and the location of the event, suggesting that the current generation of seismometers in the field could be used to provide an early warning of an incoming debris flow to residents in mudslide-prone areas.

Increasing heat drives off clouds that dampen California wildfires

Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once common low-lying morning clouds that shade many southern coastal areas of California, leading to increased risk of wildfires.

Increases in wildfire-caused erosion could impact water supply and quality in the West

A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study.
