Claim: “‘Those eruptions happened relatively early in our study period, which pushed down temperatures in the first part of the dataset, which caused the overall record to show an exaggerated warming trend,’ Christy said.

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

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This was once quite controversial: From the beginning of the satellite record in late 1978 into 1998 it showed a net global cooling trend, although ground measurements and instruments carried aloft by balloons showed warming in many areas.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Part of the cooling trend seen by the satellites can be attributed to several years of cooler than normal temperatures and cooling caused by the eruption of the Mount Pinatubo volcano.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Since the data correction of August 1998 (and the major La Niña Pacific Ocean warming event of the same year), data collected by satellite instruments has shown an average global warming trend in the atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: From November 1978 through March 2011, Earth's atmosphere has warmed at an average rate of about 0.14 C per decade, according to the UAHuntsville satellite record.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: IPCC AR4 WG1 Ch9 2007, p. 690: "Recent estimates indicate a relatively small combined effect of natural forcings on the global mean temperature evolution of the second half of the 20th century, with a small net cooling from the combined effects of solar and volcanic forcings."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Evidence for warming accumulated.

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: Some media reports have used alarmist tactics to challenge the science related to global warming by comparing it with a purported episode of global cooling.

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: In recent studies, geologists claim that global warming is one of the reasons for increased seismic activity.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: During the Climatic Research Unit email controversy (also known as "Climategate") in 2009 in the lead-up to the UN Climate Change Conference in Copenhagen, the Times wrote in an editorial "these revelations of fudged science should have a cooling effect on global-warming hysteria and the panicked policies that are being pushed forward to address the unproven theory."

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: There is a decline in stratospheric temperatures, interspersed by warmings related to volcanic eruptions.
