Claim: The amount of warming caused by the anthropogenic increase in atmospheric CO2 may be one of the most misunderstood subjects in climate science.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: "How do we know more CO2 is causing warming?".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Their effects, together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century'".

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: It is likely that anthropogenic (i.e., human-induced) warming, such as that due to elevated greenhouse gas levels, has had a discernible influence on many physical and biological systems.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The surprising effect of this is that the global warming potential of CO is three times that of CO 2.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Most of the climatic warming over the last 50 years is likely to have been caused by increased concentrations of greenhouse gases in the atmosphere.

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: Rennie 2009: "Claim 1: Anthropogenic CO2 can't be changing climate, because CO2 is only a trace gas in the atmosphere and the amount produced by humans is dwarfed by the amount from volcanoes and other natural sources.

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: As stated by the Intergovernmental Panel on Climate Change (IPCC), the largest contributor to global warming is the increase in atmospheric carbon dioxide (CO) since 1750, particularly from fossil fuel combustion, cement production, and land use changes such as deforestation.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Media coverage of global warming has had effects on public opinion on climate change, as it mediates the scientific opinion on climate change that the global instrumental temperature record shows increase 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): 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: The term "climate change" is often used to refer specifically to anthropogenic climate change (also known as global warming).
