Runaway climate change Wikipedia: 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 the feedback effects run out, possibly at a new climate state. The phrase “runaway climate change” is used to describe…

Scientists have been examining this problem intensely over recent years, as Europe, America, and Asia have all been subject…
