Claim: Scientists are "questioning the original idea that man-made global warming is what is causing the climate to change. "

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: It is "extremely likely" that this warming arises from "human activities, especially emissions of greenhouse gases" in the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The New York Times reported that "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".

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.

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).

Passage: Attribution of the temperature change to natural or anthropogenic (i.e., human-induced) factors is an important question: see global warming and attribution of recent climate change.

Passage: When then presidential candidate Rick Perry suggested that scientists were frequently questioning "that manmade global warming is what is causing the climate to change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Scientists attribute extreme weather to man-made climate change.

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: A common argument used to dismiss the significance of human-caused climate change is to allege that scientists showed concerns about global cooling which did not materialise, and there is therefore no need to heed current scientific concerns about global warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes.

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."
