Why are there so many fires in the West?
Heat and Drought Particularly warm and dry seasons predispose areas with existing fuel to added fire risk. From late 2019 into early 2020 the Western U.S. experienced record dry weather and the summer saw some record-breaking temperatures.
Why are there so many wildfires on the West Coast?
The land gets most of its moisture in the fall and winter months, and the vegetation spends most of spring and summer drying out, essentially fueling and spreading fires. The third key reason that explains why California is constantly ablaze is because of the U.S.’s ability to fight past fires.
Why are fires so frequent in the shrublands?
Plants have adapted to fire caused by the frequent lightning that occurs in the hot, dry summers.
Why are wildfires occurring in certain locations?
Common causes of wildfires include lightning, human carelessness, arson, volcano eruption, and pyroclastic cloud from active volcano. Heat waves, droughts, and cyclical climate changes such as El Niño can also have a dramatic effect on the risk of wildfires.
