claim: "...the largest of all the positive or temperature-amplifying feedbacks in  the UN’s arsenal is the water-vapor feedback.
evidences.evidence_id: Climate change feedback:128
evidences.article: Climate change feedback
evidences.evidence: Since water vapor is a greenhouse gas, the increase in water vapor content makes the atmosphere warm further; this warming causes the atmosphere to hold still more water vapor (a positive feedback), and so on until other processes stop the feedback loop.

evidences.article: Climate change feedback
evidences.evidence: The main positive feedback in global warming is the tendency of warming to increase the amount of water vapor in the atmosphere, which in turn leads to further warming.

evidences.evidence: The main reinforcing feedbacks are the water vapour feedback, the ice–albedo feedback, and probably the net effect of clouds.

evidences.evidence_id: Greenhouse gas:181
evidences.article: Greenhouse gas
evidences.evidence: Because water vapor is a greenhouse gas, this results in further warming and so is a "positive feedback" that amplifies the original warming.

evidences.evidence_id: Runaway greenhouse effect:19
evidences.article: Runaway greenhouse effect
evidences.evidence: An increase in temperature from greenhouse gases leading to increased water vapor (which is itself a greenhouse gas) causing further warming is a positive feedback, but not a runaway effect, on Earth.
