What is the climax of "There Will Come Soft Rains"?

"There Will Come Soft Rains" is a science fiction short
story by Ray Bradbury whose title is taken from a poem of the same name by Sara
Teasdale. The story tells of the nuclear destruction of Allendale, California and a
single house which stands shortly after the debacle. The house is automated: It calls
out the time of the day, prepares food for the inhabitants (now dead), and has robotic
devices which clean the home. The climax of the story comes when the house, which has
survived the nuclear blast, is accidentally set ablaze when a falling tree limb breaks
through a window, knocking over a flammable solvent. The house tries to save itself,
automatically shutting windows and setting off water sprinklers, but nature's fury
proves too powerful for the human technology inside.
