Claim: The statement that so-called greenhouse gases,  especially CO2, contribute to near-surface atmospheric warming is in  glaring contradiction to well-known physical laws relating to gas and  vapour, as well as to general caloric theory.'

Passage: In 2000, Hansen advanced an alternative view of global warming over the last 100 years, arguing that during that time frame the negative forcing via aerosols and the positive forcing via carbon dioxide (CO 2) largely balanced each other out, and that the 0.74±0.18 °C net rise in average global temperatures could mostly be explained by greenhouse gases other than carbon dioxide, such as methane and chlorofluorocarbons.

Passage: It said that Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The Intergovernmental Panel on Climate Change said the likelihood was 90 percent to 99 percent that emissions of heat-trapping greenhouse gases like carbon dioxide, spewed from tailpipes and smokestacks, were the dominant cause of the observed warming of the last 50 years.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The spatial and temporal fingerprint of warming can be traced to increasing greenhouse gas concentrations in the atmosphere, which are a direct result of burning fossil fuels, broad-scale deforestation and other human activity."

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The changes in temperature have been associated with increasing concentrations of atmospheric carbon dioxide (CO 2) and other GHGs in the atmosphere."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: As stated by the Intergovernmental Panel on Climate Change (IPCC), the largest contributor to global warming is the increase in atmospheric carbon dioxide (CO) since 1750, particularly from fossil fuel combustion, cement production, and land use changes such as deforestation.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Rennie 2009: "Claim 1: Anthropogenic CO2 can't be changing climate, because CO2 is only a trace gas in the atmosphere and the amount produced by humans is dwarfed by the amount from volcanoes and other natural sources.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: If it's greenhouse gas causing the warming the rate of warming should be higher in the troposphere than on the surface.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: If it's greenhouse gas causing the warming the rate of warming should be higher in the troposphere than on the surface.

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: 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: In the 1998 paper, "CO2-induced global warming: a skeptic's view of potential climate change" Idso said: "Several of these cooling forces have individually been estimated to be of equivalent magnitude, but of opposite sign, to the typically predicted greenhouse effect of a doubling of the air’s CO2 content, which suggests to me that little net temperature change will ultimately result from the ongoing buildup of CO2 in Earth's atmosphere.
