• What role does carbon dioxide play in climate change on Earth?
• What is the evidence that points to carbon dioxide emissions playing a significant role in climate change on Earth?

Increases in atmospheric concentrations of carbon dioxide (CO2) and other long-lived greenhouse gases such as methane, nitrous oxide and ozone have strengthened their absorption and emission of infrared radiation, causing the rise in average global temperature since the mid-20th century. Carbon dioxide is of greatest concern because it exerts a larger overall warming influence than all of these other gases combined.^[1]

As noted above, "Carbon dioxide is of greatest concern [of the various greenhouse gases] because it exerts a larger overall warming influence than all of these other gases combined."
