Claim: When the exact same group of 'experts' who claimed it was global cooling in 1977 now claim it's global warming you can easily see why I am skeptical

Passage: Trend sceptics or deniers (who deny there is global warming), [and] argue that no significant climate warming is taking place at all, claiming that the warming trend measured by weather stations is an artefact due to urbanisation around those stations ("urban heat island effect").

Passage: Many such people prefer to call themselves skeptics and describe their position as climate change skepticism.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The current scientific consensus on climate change is that the Earth underwent global warming throughout the 20th century and continues to warm.

Passage: John Wallace of the University of Washington agreed with Lindzen that progress in climate change science had been exaggerated, but said there are "relatively few scientists who are as skeptical of the whole thing as Dick [Lindzen] is".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A common argument used to dismiss the significance of human-caused climate change is to allege that scientists showed concerns about global cooling which did not materialise, and there is therefore no need to heed current scientific concerns about global warming.

Passage: The dismissive are convinced global warming is not happening.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Spencer R. Weart's history of "The Discovery of Global Warming" states that: "While neither scientists nor the public could be sure in the 1970s whether the world was warming or cooling, people were increasingly inclined to believe that global climate was on the move, and in no small way.

Passage: How many really "reject or doubt" the scientific consensus for man-made global warming?

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: During the 1970s, scientific opinion increasingly favored the warming viewpoint.

Passage: The Great Global Warming Swindle is a polemical documentary film that suggests that the scientific opinion on climate change is influenced by funding and political factors, and questions whether scientific consensus on global warming exists.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Several media pieces have claimed that since the even-at-the-time-poorly-supported theory of global cooling was shown to be false, that the well-supported theory of global warming can also be dismissed.
