Is a significant contributory factor in Global Warming human activity?
No it is not a significant factor, but it is a contributory factor. The amounts of CO2 and SOX’s release by a major volcanic eruption far surpasses the output by man’s activity. As to the amount of increasing CO2 in ice cores which the “believers” like to hold forth, that presumes that the amount of CO2 in the atmosphere is the same value over the entire globe at any given time. A change in prevailing winds, a cold period or a warm period, proximity to open water, volcanic eruptions, plankton blooms, etc. can result in radically different CO2 content within a given area compared to the rest of the global CO2 content. Unlike most gases, CO2 is more soluble in warm than in cold and is therefore greatly affected by precipitation rates and temperatures. So to leap to GLOBAL WARMING being documented by ice cores is like blind men describing an elephant — each will have his own interpretation of the same facts. At best it is a theory (but not the only one) to explain increased CO2 in ice co
