Maybe many of the monovillage problems are summed up in, "I don't disagree with the fact that the world has been slightly warming over the last 130+ years, or do I disagree that CO2 has an impact on it."
Which may be your ignorance problem, because as we have learned more and more about Global warming, its not simply about CO2 levels anymore. Because its a complex interaction of factors, and to some extent we have simply reached a certain temperature point which triggers the the release of massive amounts of methane formerly trapped in arctic permafrost. What is also clear is the fact we have changed the circulation of Ocean currents, and we do not know exactly what that will do.
To some extent, the global warming deniers assume the rise in temperature we are experiencing now is simply linear and reversible, while Global warming alarmist point out we can reach irreversible tipping points that cause the earth's climate to turn decidedly worse and unable to support much of any life. After all, in times past, the Earth has released massive amounts of sea floor methane hydride, and the following 100,000 years is hell on Earth. And that is only one such tipping point scenario out of many possible.
If nothing else, we are playing Russian Roulette with our future. Some of us may be wreck less gambler types, and others may be nervous Nellies, but when its a world wide wager, why should one group claim more rights than the other.
