Alarmists point to CO2 readings from Mauna Loa - Are they right?

Bob never ceases to put a smile on my face. Sitting on top of a volcano is the place to find where there is no CO2 contamination from volcanoes. It may be true but it is pretty funny. CO2 concentrations have never been demonstrated to drive climate change. Changing temperatures seems to drive CO2 concentration changes. I am sure that adding CO2 to the atmosphere will have some effect though it is probably very minor, potentially beneficial, and incidental to the the actual warming trends.
