Claim: There isn’t yet any empirical evidence for their claim that greenhouse gases even cause temperatures to increase.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Increases in greenhouse gases, such as by volcanic activity, can increase the global temperature and produce an interglacial period.

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): 1
Passage: During the late 20th century, a scientific consensus evolved that increasing concentrations of greenhouse gases in the atmosphere cause a substantial rise in global temperatures and changes to other parts of the climate system, with consequences for the environment and for human health.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Increases in ambient temperatures and changes in related processes are directly linked to rising anthropogenic greenhouse gas (GHG) concentrations in the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: While ‘climate change’ can be due to natural forces or human activity, there is now substantial evidence to indicate that human activity – and specifically increased greenhouse gas (GHGs) emissions – is a key factor in the pace and extent of global temperature increases.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is no convincing scientific evidence that human contribution to greenhouse gases is causing dangerous global warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate models forced by natural factors and increased greenhouse gases and aerosols reproduce the observed global temperature changes; those forced by natural factors alone do not.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The warming has not been globally uniform.

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: 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): 0
Passage: Media coverage of global warming has had effects on public opinion on climate change, as it mediates the scientific opinion on climate change that the global instrumental temperature record shows increase in recent decades and that the trend is caused mainly by human-induced emissions of greenhouse gases.
