Claim: "[T]he influence of  so-called greenhouse gases on near-surface temperature - is not yet  absolutely proven.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: "The artificial production of carbon dioxide and its influence on temperature".

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: Before the Industrial Revolution, naturally occurring amounts of greenhouse gases caused the air near the surface to be warmer by about 33 °C (59 °F) than it would be in their absence.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The presence of N2, CH4, and H2 in the atmosphere contribute to a greenhouse effect, increasing the surface temperature by 21K over the expected temperature of the body with no atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: During the late 20th century, a scientific consensus evolved that increasing concentrations of greenhouse gases in the atmosphere cause a substantial rise in global temperatures and changes to other parts of the climate system, with consequences for the environment and for human health.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The warming has not been globally uniform.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Intergovernmental Panel on Climate Change, Third Assessment Report, says: "While the radiative forcing due to greenhouse gases may be determined to a reasonably high degree of accuracy... the uncertainties relating to aerosol radiative forcings remain large, and rely to a large extent on the estimates from global modelling studies that are difficult to verify at the present time".

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: If it's greenhouse gas causing the warming the rate of warming should be higher in the troposphere than on the surface.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: If it's greenhouse gas causing the warming the rate of warming should be higher in the troposphere than on the surface.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The current trajectory of global greenhouse gas emissions does not appear to be consistent with limiting global warming to below 1.5 or 2 °C.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: On a planet with an atmosphere that can restrict emission of longwave radiation to space (a greenhouse effect), surface temperatures will be warmer than a simple planetary equilibrium temperature calculation would predict.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate models forced by natural factors and increased greenhouse gases and aerosols reproduce the observed global temperature changes; those forced by natural factors alone do not.
