Claim: In addition, [climate models] ignore the fact that enriching the atmosphere with CO2 is beneficial

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: These include carbon dioxide (chemical formula: CO 2), methane (CH 4), nitrous oxide (N 2O), and a group of gases referred to as halocarbons.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The reason for this is that human activities are adding CO2 to the atmosphere faster than natural processes can remove it (see carbon dioxide in Earth's atmosphere for a complete explanation).

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Human activity since the Industrial Revolution has increased the amount of greenhouse gases in the atmosphere, leading to increased radiative forcing from CO2, methane, tropospheric ozone, CFCs, and nitrous oxide.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: However, this excludes the balancing fluxes of CO 2 into the atmosphere from the geological reservoirs, which have slower characteristic rates.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: As the planet warms, it has been predicted that soils will add carbon dioxide to the atmosphere due to increased biological activity at higher temperatures, a positive feedback (amplification).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Unanimous agreement was found among the models that future climate change will reduce the efficiency of the land and ocean carbon cycle to absorb human-induced CO. As a result, a larger fraction of human-induced CO will stay airborne if climate change controls the carbon cycle.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "How the oceans absorb carbon dioxide is critical for predicting climate change".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: <poem>Models consistently suggest that SRM would generally reduce climate differences compared to a world with elevated GHG concentrations and no SRM; however, there would also be residual regional differences in climate (e.g., temperature and rainfall) when compared to a climate without elevated GHGs...

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Some climate change denial groups say that because CO 2 is only a trace gas in the atmosphere (roughly 400ppm, or 0.04%, 4 parts per 10,000) it can only have a minor effect on the climate.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: It should in principle, however the atmosphere is very complicated and one cannot simply argue that just because CO is a greenhouse gas it causes warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Most climate models include the radiative effects of greenhouse gases such as carbon dioxide.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: This article is about climate change scenarios.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The CO2 fertiliser effect has been greatly overestimated during Free-Air Carbon dioxide Enrichment (FACE) experiments where results show increased CO2 levels in the atmosphere enhances photosynthesis, reduce transpiration, and increase water use efficiency (WUE).
