Claim: more than 100 per cent of the warming over the past century is due to human actions.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The view that human activities are likely responsible for most of the observed increase in global mean temperature ("global warming") since the mid-20th century is an accurate reflection of current scientific thinking.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Human-caused increases in greenhouse gases are responsible for most of the observed global average surface warming of roughly 0.8 °C (1.5 °F) over the past 140 years.

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 global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases.

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: Most of the global warming since the mid-20th century is very likely due to human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
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): 0
Passage: Some of the main human activities that contribute to global warming are:

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Global warming refers to the warming caused by human technology since the 19th century or earlier.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The dominant cause of the warming since the 1950s is human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: GHG emissions due to anthropogenic (human) activity are the dominant cause of observed global warming (climate change) since the mid-20th century.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Since the mid-20th century, most of the observed warming is "likely" (greater than 66% probability, based on expert judgement) due to human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Recent scientific assessments find that most of the warming of the Earth's surface over the past 50 years has been caused by human activities (see also the section on scientific literature and opinion).
