claim: Increased CO2 makes more water vapor, a greenhouse gas which amplifies warming
evidences.evidence_id: Carbon dioxide:192
evidences.article: Carbon dioxide
evidences.evidence: Increases in atmospheric concentrations of CO 2 and other long-lived greenhouse gases such as methane, nitrous oxide and ozone have correspondingly strengthened their absorption and emission of infrared radiation, causing the rise in average global temperature since the mid-20th century.

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: Polar amplification:33
evidences.article: Polar amplification
evidences.evidence: That’s important because water vapor is a greenhouse gas just like carbon dioxide and methane.
