Claim: Carbon dioxide is a non-condensable atmospheric gas like nitrogen and oxygen

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The gaseous products of complete reaction are typically carbon dioxide, steam, and nitrogen.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The most common gases in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.9%).

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Natural gas (also called fossil gas) is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Like landfill gas, biogas is mostly methane and carbon dioxide, with small amounts of nitrogen, oxygen and hydrogen.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide in Earth's atmosphere is a trace gas, currently (mid 2018) having a global average concentration of 409 parts per million by volume (or 622 parts per million by mass).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Atmospheric carbon dioxide plays an integral role in the Earth's carbon cycle whereby carbon dioxide is removed from the atmosphere by some natural processes such as photosynthesis and deposition of carbonates, to form limestones for example, and added back to the atmosphere by other natural processes such as respiration and the acid dissolution of carbonate deposits.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon fixation is a biochemical process by which atmospheric carbon dioxide is incorporated by plants, algae and (cyanobacteria) into energy-rich organic molecules such as glucose, thus creating their own food by photosynthesis.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide hydrate is a snow-like crystalline substance composed of water ice and carbon dioxide.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: After water vapour (concentrations of which humans have limited capacity to influence) carbon dioxide is the most abundant and stable greenhouse gas in the atmosphere (methane rapidly reacts to form water vapour and carbon dioxide).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is a greenhouse gas that increases radiative forcing and contributes to global warming along with ocean acidification.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: While transparent to visible light, carbon dioxide is a greenhouse gas, absorbing and emitting infrared radiation at its two infrared-active vibrational frequencies (see the section "Structure and bonding" above).
