Claim: Prof Adam Scaife, a climate modelling expert at the UK’s Met Office, said the evidence for a link to shrinking Arctic ice was now good: ‘The consensus points towards that being a real effect.’”

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Scaife and his team have made recent advances in long range weather forecasting and have uncovered a signal to noise paradox in climate models that makes them better at predicting the real climate than they are at predicting themselves.

Passage: In response to the incident, 1,700 British scientists signed a joint statement circulated by the UK Met Office declaring their "utmost confidence in the observational evidence for global warming and the scientific basis for concluding that it is due primarily to human activities".

Passage: Ben Keene, the atlas's editor, commented: "In the last two or three decades, global warming has reduced the size of glaciers throughout the Arctic and earlier this year, news sources confirmed what climate scientists already knew: water, not rock, lay beneath this ice bridge on the east coast of Greenland.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The American Meteorological Society (AMS) statement adopted by their council in 2012 concluded: There is unequivocal evidence that Earth's lower atmosphere, ocean, and land surface are warming; sea level is rising; and snow cover, mountain glaciers, and Arctic sea ice are shrinking.

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."

Passage: The Arctic Climate Impact Assessment (ACIA) is a study describing the ongoing climate change in the Arctic and its consequences: rising temperatures, loss of sea ice, unprecedented melting of the Greenland ice sheet, and many impacts on ecosystems, animals, and people.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: This relationship has been documented through observation evidence and model responses to sea ice loss according to the 2017 Wiley Periodicals Article, Amplified Arctic warming and mid latitude weather: new perspectives on emerging connections.

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.

Passage: Ice–albedo feedback plays an important role in global climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report states that greenhouse gas forcing is predominantly responsible for the decline in Arctic sea ice extent.

Passage: Studies published in 2017 and 2018 identified stalling patterns of rossby waves, in the northern hemisphere jet stream, to have caused almost stationary extreme weather events, such as the 2018 European heatwave, the 2003 European heat wave, 2010 Russian heat wave, 2010 Pakistan floods - these events have been linked to global warming, the rapid heating of the Arctic.

Passage: "A controversy over leaked e-mails exchanged among global warming scientists is part of a 'smear campaign' to derail next month's United Nations climate summit in Copenhagen, one of the scientists, meteorologist Michael Mann, said Tuesday...Climate change sceptics 'don't have the science on their side any more, so they've resorted to a smear campaign to distract the public from the reality of the problem and the need to confront it head-on in Copenhagen' said Mann"; Feldman, Stacy (25 November 2009).
