macrae, I think we are all aware of the greenhouse effect, and accept that CO2 levels are rising.
However this doesn't help explain previous warming periods and ice ages where the data collected indicates that the warming preceded rising CO2 levels. Now if you have links to scientific data that prove the opposite, ie. that rising CO2 levels preceded rising temperatures I would appreciate it if you can post them here.
