claim: at the end of recent ice ages, the concentration of carbon dioxide in the atmosphere started to rise only after temperatures began to climb.
evidences.evidence_id: Carbon dioxide in Earth's atmosphere:5
evidences.article: Carbon dioxide in Earth's atmosphere
evidences.evidence: Concentrations of CO 2 in the atmosphere were as high as 4,000 parts per million (ppm, on a molar basis) during the Cambrian period about 500 million years ago to as low as 180 ppm during the Quaternary glaciation of the last two million years.

evidences.evidence_id: Carbon dioxide in Earth's atmosphere:6
evidences.article: Carbon dioxide in Earth's atmosphere
evidences.evidence: Reconstructed temperature records for the last 420 million years indicate that atmospheric CO 2 concentrations peaked at ~2000 ppm during the Devonian (∼400 Myrs ago) period, and again in the Triassic (220–200 Myrs ago) period.

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: Ice age:0
evidences.article: Ice age
evidences.evidence: An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.
