Claim: Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.

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: 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): 1
Passage: Human activities (primarily greenhouse gas emissions) are the primary cause.

Passage: AIBS Position Statements "Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
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: 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: European Science Foundation in a 2007 position paper states: There is now convincing evidence that since the industrial revolution, human activities, resulting in increasing concentrations of greenhouse gases have become a major agent of climate change ... On-going and increased efforts to mitigate climate change through reduction in greenhouse gases are therefore crucial.

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: 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.

Passage: American Physical Society Climate Change Policy Statement, November 2007 "Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate.

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: GHG emissions due to anthropogenic (human) activity are the dominant cause of observed global warming (climate change) since the mid-20th century.
