We weren't around 600,000 years ago to drive that sort of climate change. Other factors were in play... such as wobbling of the Earth's orbit. You're comparing apples to oranges. To quote the article you posted from skepticalscience.com (which refutes your position)... "A 2012 study by Shakun et al. looked at temperature changes 20,000 years ago (the last glacial-interglacial transition) from around the world and added more detail to our understanding of the CO2-temperature change relationship. They found that: The Earth's orbital cycles triggered warming in the Arctic approximately 19,000 years ago, causing large amounts of ice to melt, flooding the oceans with fresh water. This influx of fresh water then disrupted ocean current circulation, in turn causing a seesawing of heat between the hemispheres.The Southern Hemisphere and its oceans warmed first, starting about 18,000 years ago. As the Southern Ocean warms, the solubility of CO2 in water falls. This causes the oceans to give up more CO2, releasing it into the atmosphere."
