Best summary I’ve seen yet for demolishing the theory of anthropogenic (manmade) global warming (AGW).

Fact-based climate debate
By Lee C.Gerhard,
IPCC Expert Reviewer
It is crucial that scientists are factually accurate when they do speak out, that they ignore media hype and maintain a clinical detachment from social or other agendas. There are facts and data that are ignored in the maelstrom of social and economic agendas swirling about Copenhagen.
Greenhouse gases and their effects are well-known. Here are some of things we know:
– The most effective greenhouse gas is water vapor, comprising approximately 95 percent of the total greenhouse effect.
– Carbon dioxide concentration has been continually rising for nearly 100 years. It continues to rise, but carbon dioxide concentrations at present are near the lowest in geologic history.
– Temperature change correlation with carbon dioxide levels is not
statistically significant.
– There are no data that definitively relate carbon dioxide levels to
temperature changes.
– The greenhouse effect of carbon dioxide logarithmically declines with
increasing concentration. At present levels, any additional carbon dioxide can have very little effect.
We also know a lot about Earth temperature changes…
