Claim: We’re not sure because we don’t have enough data, for long enough, to separate signal from noise,” said Eric J. Steig, a scientist at the University of Washington who has studied temperature trends in Antarctica.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In a study released in 2009, historical weather station data was combined with satellite measurements to deduce past temperatures over large regions of the continent, and these temperatures indicate an overall warming trend.

Passage: One of the paper's authors, Eric Steig of the University of Washington, stated "We now see warming is taking place on all seven of the earth’s continents in accord with what models predict as a response to greenhouse gases."

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A study by Eric Steig published in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica is slightly positive at >0.05 °C (0.09 °F) per decade from 1957 to 2006.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Using the long-term temperature trends for the earth scientists and statisticians conclude that it continues to warm through time.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Research published in 2009 found that overall the continent had become warmer since the 1950s, a finding consistent with the influence of man-made climate change: "We can't pin it down, but it certainly is consistent with the influence of greenhouse gases from fossil fuels", said NASA scientist Drew Shindell, another study co-author.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is evidence from one study that Antarctica is warming as a result of human carbon dioxide emissions, but this remains ambiguous.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Detection of a climate signal does not always imply significant attribution.

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: Although all the datasets show the expected tropospheric amplification at seasonal and annual timescales it is still debated whether or not the long term trends are consistent with the expected moist adiabatic lapse rate amplification due to difficulty of producing homogenized datasets, some satellite temperature reconstruction are consistent with the expected amplification while others are not.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The cause of the cooling trend is not known with certainty.

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: Scientist seek periods that are in some sense analogous or informative to current climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: [1] In their latest study (September 20, 2007) NASA researchers have confirmed that Antarctic snow is melting farther inland from the coast over time, melting at higher altitudes than ever and increasingly melting on Antarctica's largest ice shelf.
