Claim: Postma's model contains many simple errors; in no way does Postma undermine the existence or necessity of the greenhouse effect.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Since it is absurd to have no logical method for settling on one hypothesis amongst an infinite number of equally data-compliant hypotheses, we should choose the simplest theory: "Either science is irrational [in the way it judges theories and predictions probable] or the principle of simplicity is a fundamental synthetic a priori truth."

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Thus, complex hypotheses must predict data much better than do simple hypotheses before researchers reject the simple hypotheses.

Passage: Minimum description length Minimum message length – Formal information theory restatement of Occam's Razor Newton's flaming laser sword Philosophical razor – Principle or rule of thumb that allows one to eliminate unlikely explanations for a phenomenon Philosophy of science – The philosophical study of the assumptions, foundations, and implications of science Simplicity "Ockham's razor does not say that the more simple a hypothesis, the better."

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In the 25 papers with quantitative comparisons, complexity increased forecast errors by an average of 27 percent.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Population genetics must either model this complexity in detail, or capture it by some simpler average rule.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Climate models forced by natural factors and increased greenhouse gases and aerosols reproduce the observed global temperature changes; those forced by natural factors alone do not.

Passage: Insertion of bugs into climate models?

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Intergovernmental Panel on Climate Change, Third Assessment Report, says: "While the radiative forcing due to greenhouse gases may be determined to a reasonably high degree of accuracy... the uncertainties relating to aerosol radiative forcings remain large, and rely to a large extent on the estimates from global modelling studies that are difficult to verify at the present time".

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Though the model showed no significant changes to the climate in areas other than the Tropics, this may not be the case since the model has possible errors and the results are never absolutely definite.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: It should in principle, however the atmosphere is very complicated and one cannot simply argue that just because CO is a greenhouse gas it causes 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: For coupled atmosphere-ocean global climate models (e.g. CMIP5) the climate sensitivity is an emergent property : it is not a model parameter, but rather a result of a combination of model physics and parameters.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Since orbital variations are predictable, any model that relates orbital variations to climate can be run forward to predict future climate, with two caveats: the mechanism by which orbital forcing influences climate is not definitive; and non-orbital effects can be important (for example, Human impact on the environment principally increases in greenhouse gases result in a warmer climate).
