So, how do we argue the global warming point?
Just deal in facts:
The reality is a doubling of atmospheric CO2 concentration over current levels, that the IPCC "story line" pretends, even if true, could not induce significant temperature change whatever its source.
Mankind's impact is only 0.28% of Total Greenhouse effect
" There is no dispute at all about the fact that even if punctiliously observed, (the Kyoto Protocol) would have an imperceptible effect on future temperatures -- one-twentieth of a degree by 2050. "
Dr. S. Fred Singer, atmospheric physicist
Professor Emeritus of Environmental Sciences at the University of Virginia,
and former director of the US Weather Satellite Service;

Climate Catastrophe, A spectroscopic Artifact?
Climatic temperature change, OTOH, generally gives rise to changes in atmospheric CO2 concentration through changes of biomass, warming of ocean with release of CO2 from solution with rising temperatures.
Climatic temperature is predominantly a consequence of Solar heating/cooling arising from variation of solar radiance,

plus astronomical & geophysical events affecting surface & atmospheric albedo.

Globally Averaged Atmospheric Temperatures
This chart shows the monthly temperature changes for the lower troposphere - Earth's atmosphere from the surface to 8 km, or 5 miles up. The temperature in this region is more strongly influenced by oceanic activity, particularly the "El Niño" and "La Niña" phenomena, which originate as changes in oceanic and atmospheric circulations in the tropical Pacific Ocean. The overall trend in the tropospheric data is near zero, being +0.04 C/decade through Feb 2002. Click on the chart to get the numerical data.

Seems as though there is room for substantial doubt as to any negative effect human created CO2, Methane etc. may have on our Climate future.
At least these folks believe so:
Petition Project: http://www.oism.org/pproject/s33p357.htm
During the past 2 years, more than 17,100 basic and applied American scientists, two-thirds with advanced degrees, have signed the Global Warming Petition.
Specifically declaring:
"There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate."
Signers of this petition so far include 2,660 physicists, geophysicists, climatologists, meteorologists, oceanographers, and environmental scientists (select this link for a listing of these individuals) who are especially well qualified to evaluate the effects of carbon dioxide on the Earth's atmosphere and climate.
Signers of this petition also include 5,017 scientists whose fields of specialization in chemistry, biochemistry, biology, and other life sciences (select this link for a listing of these individuals) make them especially well qualified to evaluate the effects of carbon dioxide upon the Earth's plant and animal life.
Nearly all of the initial 17,100 scientist signers have technical training suitable for the evaluation of the relevant research data, and many are trained in related fields.
