[citation needed] In some regions, such as the western United States, wildfires are responsible for an increase in burn ...
In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues. Different flame types of a Bunsen burner depend on oxygen supply.

The longer fire seasons are due to the increased heat and length of summer and spring, which are the most common seasons for wildfires. [20] These longer seasons also start earlier due to the loss of snowpack during the winter causing less moisture in summer soil making it better fuel for wildfires.
