Claim: The Petition Project features over 31,000 scientists signing the petition stating "there is no convincing scientific evidence that human release of carbon dioxide will, in the forseeable future, cause catastrophic heating of the Earth's atmosphere".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
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): 1
Passage: In November 2017, a second warning to humanity signed by 15,364 scientists from 184 countries stated that "the current trajectory of potentially catastrophic climate change due to rising greenhouse gases from burning fossil fuels, deforestation, and agricultural production – particularly from farming ruminants for meat consumption" is "especially troubling".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Evidence from the geological record is consistent with the physics that shows that adding large amounts of carbon dioxide to the atmosphere warms the world and may lead to: higher sea levels and flooding of low-lying coasts; greatly changed patterns of rainfall; increased acidity of the oceans; and decreased oxygen levels in seawater.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: 7–10 "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.

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: The petition contained the names of "around 300 eminent scientists and other qualified individuals", and called on the United States and other nations to “change course on an outdated international agreement that targets minor greenhouse gases,” starting with carbon dioxide.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate change denialism is the prime example, where a handful of scientists, allied with an effective PR machine, are publicly challenging the scientific consensus that global warming is real and is due primarily to human consumption of fossil fuels.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The film features scientists and others who are sceptical that global warming is caused by human activity.

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: How many really "reject or doubt" the scientific consensus for man-made global warming?

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Science education is under attack… by climate change deniers, who ignore a mountain of evidence gathered over the last fifty years that the planet is warming and that humans are largely responsible.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Boucher's review concludes: "Movies like Cowspiracy aren’t believable, not only because of how they twist the science, but also because of what they ask us to believe: that the fossil fuel industry—the ExxonMobils of the world—aren’t the main cause of global warming... and that thousands of scientists have covered up the truth about the most important environmental issue of our time.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The human cost associated with denying climate change science is one that concerns many governments.
