Perfectly correct, however, the Anthropogenic Global Warming disciples do use fuzzy logic. Their basic premise is that Global Warming is occurring; no denying that it is, CO2 levels are going up, no denying that they are and most of the new CO2 is from fossil fuels, it is. Ergo; fossil fuel generated CO2 increase is causing Global Warming. They make the mistake of assuming a correlation means a cause. Then they extrapolate and predict all manner of catastrophes; extinctions and all manner of things. However, 6000 years ago global temperatures were some 6 to 8 degrees higher than now; this was known as the Climatic Optimum and there is ample evidence for it. So if mass extinction and wordlwide disruption of ecosystems are going to occur in the future due to an increase of 2 degrees surely it must have occurred in the past with the warming of the Climatic Optimum? There is absolutely no evidence that this did occur and the alarmist claims that it will occur in the future are without foundation.
