Claim: contrary to the hypothesis that rising temperature is caused by increasing CO2.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: 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.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Not only do increasing carbon dioxide concentrations lead to increases in global surface temperature, but increasing global temperatures also cause increasing concentrations of carbon dioxide.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Singer argues, contrary to the scientific consensus on climate change, that there is no evidence that global warming is attributable to human-caused increases in atmospheric carbon dioxide, and that humanity would benefit if temperatures do rise.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Singer argues there is no evidence that the increases in carbon dioxide produced by humans cause global warming, and that if temperatures do rise it will be good for humankind.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In the scientific literature, there is an overwhelming consensus that global surface temperatures have increased in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "How do we know more CO2 is causing warming?".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "The artificial production of carbon dioxide and its influence on temperature".

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.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Intergovernmental Panel on Climate Change (IPCC) reports that increased quantities of the greenhouse gas carbon dioxide within the atmosphere will "very likely" lead to higher average temperatures on a global scale (global warming).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Global warming is the result of increasing atmospheric carbon dioxide concentrations which is caused primarily by the combustion of fossil energy sources such as petroleum, coal, and natural gas, and to an unknown extent by destruction of forests, increased methane, volcanic activity and cement production.

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: Carbon dioxide is the primary greenhouse gas that is contributing to recent climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.
