ELI5: Why does California burst into flames every summer?
gpt
It's quite hot and dry there. The climate dries out lots of the underbrush, making it easy fuel.

Areas like that are also supposed to naturally burn. Forest fires are actually quite beneficial as they clear out the underbrush, fertilize the ground, and actually cause some species of trees to start growing (the fire is a vital step in their reproduction). However, many people stop fires from happening so the dry underbrush builds up for years. When it finally does catch there's several years worth of material there and the fires get large and out of control.
