According to researchers, dry weather, unusually warm temperatures, and widespread use of fireworks are significantly increasing the chance of wildfires throughout the U.S. in advance of the July 4 holiday. They warn that even a tiny spark can ignite very large wildfires in areas that are suffering from drought.

Millions of Americans will celebrate Independence Day this year as it is the 250th anniversary of our nation, thus fireworks will be displayed in many cities across the nation and held at many residential locations. The western half of the U.S., the southeast U.S., and the Great Plains region of the country are currently experiencing moderate to exceptional drought conditions, while many of the surrounding areas also continue to experience above-normal temperatures.

Fireworks are considered to be one of the most prevalent forms of human-started wildfires on Independence Day. The National Fire Protection Association reported that there were approximately 32,000 fires caused by using fireworks in 2023. Historically, July 4 has always recorded the largest amount of human-caused wildfire ignitions compared to any other day of the year. Between 1992 and 2020, there were approximately 15,000 wildfires reported as a result of the use of fireworks on Independence Day.

A combination of three factors is necessary for wildfires to occur: dry vegetation, favorable weather conditions for fires to spread, and an ignition source. Fireworks used during the celebration of Independence Day become an ignition source in many cases. The fire may start because of hot weather, low moisture levels, and wind.

Several states and city governments prohibit the use of fireworks in places where there is a high risk of wildfire occurrence. People are urged to participate in professional fireworks shows or switch to some alternatives like drone light shows in case such measures are introduced.

Moreover, fireworks are dangerous to people not only because they may cause wildfires. According to statistics, 9,700 people suffered from fireworks-related injuries in 2023 in the US. Hand, face, and ear burns are typical injuries caused by fireworks, and one out of three victims is a child.

Scientists suggest that forbidding people to set up consumer fireworks on hot days will result in fewer preventable wildfires and reduced pressure on firefighters who work during one of the busiest periods.
