So what we have here is a fruit loopy anonymous poster on a message board claiming that he knows more than all the scientists on this planet. As for #'s 1 and two;
The Carbon Dioxide Greenhouse Effect
The American Institute of Physics is the largest Scientific Society on this planet. And it and every other Scientific Society, as well as all the National Academies of Science and the major Universities state that AGW is real, and a clear and present danger.
The amount of land at the poles is a factor in the ice ages, but more important factors are the GHGs in the atmosphere and the Milankovic Cycles. There have been vast geological periods when there was land covering the South Pole, and there was no continental ice sheets there.
The two primary drivers of climate are the amount of energy the sun recieves from the sun, and the amount it retains. The latter is controlled by the Earth's albedo, and the amount of GHGs in the atmosphere. Land distribution, Milankovic Cycles, effect the distribution of the heat and cold on earth, but are not primary drivers.
CO2, being the primary GHG, not the strongest one, that is water vapor, but the primary one. CO2 controls the amount of water vapor in the atmosphere. All the physicists state that.
