"Because there is considerable uncertainty in current understanding of how the climate system varies naturally and reacts to emissions of greenhouse gases and aerosols, current estimates of the magnitude of future warming should be regarded as tentative and subject to future adjustments (either upward or downward)." -- Climate Change Science - An Analysis Of Some Key Questions, p1 (Committee on the Science of Climate Change, National Research Council) ISBN 0-309-07574-2.
"In sum, a strategy must recognize what is possible. In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the prediction of a specific future climate state is not possible." -- Final chapter, Draft TAR 2000 (Third Assessment Report), IPCC (Intergovernmental Panel on Climate Change).
"At this point in the debate, it is intellectually dishonest and borders on fraudulent to continue to maintain that there is any reasonable basis to fear a coming climate apocalypse. Yet the scientific establishment continues to grind out tortured "studies" to prove black is white. Those involved in this charade are doing lasting damage to science and the reputations of scientists. Hell, you are no different than the worst lawyers - you will say whatever people want you to say so long as you are paid." -- Fred Palmer, president of the Greening Earth Society.
Global warming is NOT caused by humans. If you believe it is your are factually impaired.
