Claim: There is no empirical evidence that increasing greenhouse gases are the primary cause of Global Warming

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: Scientists have determined that the major factors causing the current climate change are greenhouse gases, land use changes, and aerosols and soot.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Cumulative anthropogenic (i.e., human-emitted) emissions of CO 2 from fossil fuel use are a major cause of global warming, and give some indication of which countries have contributed most to human-induced climate change.

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: There is a scientific consensus that climate is changing and that greenhouse gases emitted by human activities are the primary driver.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Retrieved 2010-08-28. the leading international network of climate scientists has concluded for the first time that global warming is 'unequivocal' and that human activity is the main driver, 'very likely' causing most of the rise in temperatures since 1950 Stevens, William K. (2007-02-06).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: US National Academy of Sciences: "In the judgment of most climate scientists, Earth's warming in recent decades has been caused primarily by human activities that have increased the amount of greenhouse gases in the atmosphere.

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: 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: 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: 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.
