Claim: Many lines of evidence, including simple accounting, demonstrate beyond a shadow of a doubt that the increase in atmospheric CO2 is due to human fossil fuel burning.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: While CO 2 absorption and release is always happening as a result of natural processes, the recent rise in CO 2 levels in the atmosphere is known to be mainly due to human (anthropogenic) activity.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The introduction includes this statement: There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Human activities, primarily the burning of fossil fuels (coal, oil, and natural gas), and secondarily the clearing of land, have increased the concentration of carbon dioxide, methane, and other heat-trapping ("greenhouse") gases in the atmosphere...There is international scientific consensus that most of the warming observed over the last 50 years is attributable to human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
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): 0
Passage: Network of African Science Academies: "A consensus, based on current evidence, now exists within the global scientific community that human activities are the main source of climate change and that the burning of fossil fuels is largely responsible for driving this change."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A consensus, based on current evidence, now exists within the global scientific community that human activities are the main source of climate change and that the burning of fossil fuels is largely responsible for driving this change...

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: One argument is that of global warming occurring due to human-caused emission of greenhouse gases, particularly carbon dioxide produced by the burning of fossil fuels.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: [clarification needed] This increase is the result of human activities by burning fossil fuels, deforestation and forest degradation in tropical and boreal regions.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Modern climate change is driven by the human emissions of greenhouse gas from the burning of fossil fuel driving up global mean surface temperatures.

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: Humans have drastically added to the amount of carbon dioxide () in the atmosphere through the burning of fossil fuels and the process of deforestation.
