Claim: Research has found a human influence on the climate of the past several decades ...

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: According to the Intergovernmental Panel on Climate Change (IPCC), it is "extremely likely" that human influence was the dominant cause of global warming between 1951 and 2010.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Like the warming "signal" that has gradually emerged from the "noise" of natural climate variability, the scientific evidence for a human influence on global climate has accumulated over the past several decades, from many hundreds of studies.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This report explicitly endorses the IPCC view of attribution of recent climate change as representing the view of the scientific community: The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Human influence on the climate system is clear.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The available evidence suggests very strongly that human activities have already begun to make significant changes to the earth's climate, and that the long-term risk of delaying action is greater than the cost of avoiding/minimising the risk."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is a clear human influence on the climate It is extremely likely that human influence has been the dominant cause of observed warming since 1950, with the level of confidence having increased since the fourth report.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Decades of scientific research have shown that climate can change from both natural and anthropogenic causes.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The balance of evidence suggests a discernible human influence on global climate (considerable progress since the 1990 report in distinguishing between natural and anthropogenic influences on climate, because of: including aerosols; coupled models; pattern-based studies) Climate is expected to continue to change in the future (increasing realism of simulations increases confidence; important uncertainties remain but are taken into account in the range of model projections) There are still many uncertainties (estimates of future emissions and biogeochemical cycling; models; instrument data for model testing, assessment of variability, and detection studies) The Third Assessment Report (TAR) was completed in 2001 and consists of four reports, three of them from its Working Groups: Working Group I: The Scientific Basis Working Group II: Impacts, Adaptation and Vulnerability Working Group III: Mitigation Synthesis Report A number of the TAR's conclusions are given quantitative estimates of how probable it is that they are correct, e.g., greater than 66% probability of being correct.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: ... there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: "From new estimates of the combined anthropogenic forcing due to greenhouse gases, aerosols, and land surface changes, it is extremely likely (>95%) that human activities have exerted a substantial net warming influence on climate since 1750."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report concluded, "It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Multiple lines of evidence support attribution of recent climate change to human activities:

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Media coverage of climate change 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.
