Much of the western U.S. remains in the grip of an unrelenting drought. This dryness has coincided with record-breaking wildfires, intense and long-lasting heat waves, and western reservoirs Lake Mead and Lake Powell now at their lowest levels ever recorded.

Following 2020 and 2021鈥攖he fifth and fourth hottest years on record in the United States respectively鈥2022 is on track to become one of the 10 hottest years worldwide. The western U.S. has also seen some of its most devastating wildfires in the past three years, including the Marshall Fire on Dec. 30, 2021, the most destructive fire in Colorado state history.

精品SM在线影片 researchers offer insight into everything from how a changing climate will impact water supplies, crops and landscapes to how best to protect homes and our health from fire and smoke.

Wildfire Research

Promoting public impact: The Marshall Fire grants

Six grants and one sponsorship have been awarded by the Office for Outreach and Engagement to support community-engaged scholarship connected to the Marshall Fire. The grants are in partnership with the Research & Innovation Office and the Natural Hazards Center.

The CIRES Earth Lab has confirmed a palpable change in fire dynamics already suspected by many: Large fires have not only become more common, they are also spreading into new areas, impacting land that previously did not burn.

Forest fires can have a significant long-term effect on the amount of water flowing in nearby rivers and streams. With forest fires on the rise in the western U.S., that phenomenon is increasingly influencing the region鈥檚 water supply as well as the risk for flooding and landslides.

Historically, night is the critical time for slowing a speeding fire, and nature's wildfire brakes are failing. According to CIRES Earth Lab research, nighttime fires have become more intense, as hot, dry nights are more commonplace.

精品SM在线影片 researchers from across campus have pivoted to study the aftermath of the Marshall Fire, hoping to learn from a tragedy in their own backyard and help prepare the country for the next 鈥渃limate fire.鈥

If you really listen, survivors and emergency responders will tell you what they need

Survivors may face what sociologist Lori Peek calls "the long tail of disaster-related trauma." She argues these survivors need mental health resources and support from friends and family long after the television cameras are gone.

Fire Safety Tips

While many wildfires are caused by lightning strikes, others are human caused (e.g., careless cigarette disposal, fireworks, camp fires). Please use extreme caution when enjoying the outdoors, within the city of Boulder and in the surrounding areas. Make a plan to immediately leave the area if threatened by a wildfire and follow instructions from firefighting and emergency management officials.

Fireworks pose a significant fire risk. The possession or discharge of fireworks, firecrackers or skyrockets is prohibited in the city of Boulder and Boulder County. Violations of law are enforced under the CU Student Code of Conduct and can result in sanctions such as probation, fines or educational courses.

If you find yourself in possession of fireworks, you can turn them into any of the local Boulder fire departments鈥撯搉o questions asked! The fire department will dispose of the fireworks in a responsible manner for you.听
