Runaway climate change describes a scenario in which the climate system passes a threshold or tipping point, after which internal positive feedback effects cause the climate to continue changing, even absent further external forcings. The runaway climate change continues until it is overpowered by negative feedback effects which cause the climate system to restabilise at a new state.
The phrase "runaway climate change" is used to describe a theory in which positive feedbacks result in rapid climate change. It is used in the popular media and by environmentalists with reference to concerns about rapid global warming. Some astronomers use the similar expression runaway greenhouse effect to describe a situation where the climate deviates catastrophically and permanently from the original state - as happened on Venus. It is rarely used in relation to climate change events in climatological literature.

“Ghosts, we hope, may be always with us—that is, never too far out of the reach of fancy. On the whole, it would seem they adapt themselves well, perhaps better than we do, to changing world conditions—they enlarge their domain, shift their hold on our nerves, and, dispossessed of one habitat, set up house in another. The universal battiness of our century looks like providing them with a propitious climate ...”
—Elizabeth Bowen (1899–1973)
“All photographs are there to remind us of what we forget. In this—as in other ways—they are the opposite of paintings. Paintings record what the painter remembers. Because each one of us forgets different things, a photo more than a painting may change its meaning according to who is looking at it.”
—John Berger (b. 1926)
