A Change of Climate is a novel by English author Hilary Mantel, first published in 1994 by Viking Books.

[3] A Change of Climate is set in Norfolk in 1980, and concerns Ralph and Anna Eldred, parents of four children, whose family life threatens to disintegrate in the course of one summer, when memories which they have repressed fiercely for twenty years resurface to disrupt the purposive and peaceful lives they have tried to lead since a catastrophic event overtook them early in their married life.

The action of the novel moves back to the late 1950s, when they worked for a missionary society in a dangerous and crowded South African township, and then follows the couple to Bechuanaland, where in the loneliness of a remote mission station an unspeakable loss occurs.

The novel is about the possibility or impossibility of forgiveness, the clash of ideals and brutality, and the need to acknowledge that lives are broken before they can begin to be mended.

In Botswana in 1977 she read law reports about medicine murders and the theft of children; later she heard of an 'apparently happily married couple who suddenly split up after doing all the hard work of bringing up a family'.
