Global warming and the economy

"The National Oceanic and Atmospheric Administration reported that October in the US was marked by 63 record snowfalls and 115 lowest-ever temperatures. Over the past few years, similar signs of colder than usual weather have been recorded all over the world, causing many people to question the still fashionable, but now long outdated, global warming alarmism. Yet individual weather events or spells, whether warmings or coolings, tell us nothing necessarily about true climate change. . .

Introduction of a carbon dioxide tax to prevent (imaginary) warming, euphemistically disguised as an emissions trading scheme, is a politician's, ticket clipper's and mafia chief's dream. . ." Australian, Jan. 20, 2009

"The IPCC’s assertion that a dangerous human influence is being exerted on climate change rested in 2001 on three main arguments. These were (i) that the thermometer-based ground-temperature record shows unprecedented warming; (ii) the claim, after the Mann et al. (1998) ‘hockey stick’model of climate change, that late 20th century temperatures rose to an unnatural level and at an unnatural rate; and (iii) the implication, based on a radiative-balance model of atmospheric processes, that deterministic computer models can predict climate 50 or 100 years ahead.

Regarding (i), the ground temperature curve now shows no statistically significant warming since 1995, and cooling since 2002. Regarding (ii), the work of Mann et al. has been shown to be deeply statistically flawed (McIntyre and McKitrick 2003). Which leaves GCM computer models as the sole remaining argument for dangerous human-caused warming. ‘How are they travelling’, you ask? ‘Not at all well’ is the answer. . ." from "Knock, Knock: Where is the Evidence for Dangerous Human-Caused Global Warming?" by Robert M.
