Claim: Postma disproved the greenhouse effect.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: One reason for the difference between the two values is due to the greenhouse effect, which increases the average temperature of the Earth's surface.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Simultaneously, the clouds enhance the greenhouse effect, warming the planet.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: It was demonstrated experimentally (R. W. Wood, 1909) that a (not heated) "greenhouse" with a cover of rock salt (which is transparent to infrared) heats up an enclosure similarly to one with a glass cover.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The consensus theory of the scientific community is that the resulting greenhouse effect is a principal cause of the increase in global warming which has occurred over the same period, and a chief contributor to the accelerated melting of the remaining glaciers and polar ice.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The ice age continues until the reduction in weathering causes an increase in the greenhouse effect.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The greenhouse effect is a process by which thermal radiation from a planetary atmosphere warms the planet's surface beyond the temperature it would have in the absence of its atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Release of greenhouse gases from thawed permafrost to the atmosphere increases global warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Rennie 2009: "Claim 1: Anthropogenic CO2 can't be changing climate, because CO2 is only a trace gas in the atmosphere and the amount produced by humans is dwarfed by the amount from volcanoes and other natural sources.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: At a meeting of the American Geophysical Union (December 17, 2008), scientists detailed evidence in support of the controversial idea that the introduction of large-scale rice agriculture in Asia, coupled with extensive deforestation in Europe began to alter world climate by pumping significant amounts of greenhouse gases into the atmosphere over the last 1,000 years.

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

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The effect of combustion-produced carbon dioxide on the global climate, a special case of the greenhouse effect first described in 1896 by Svante Arrhenius, has also been called the Callendar effect.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Additionally, the global warming induced thawing of the permafrost, which stores about two times the amount of the carbon currently released in the atmosphere, releases the potent greenhouse gas, methane, in a positive feedback cycle that is feared to lead to a tipping point called runaway climate change.
