Looks at the CO2 levels in the atmosphere in the last two glacial/interglacial cycles. In the ramping up of the decay of the ice sheets the CO2 rose about 50-60 ppm per 300 years and never went up above 300 ppm. We have raised it by 100 ppm in less than 100. Same with temperature.

Everyone knows climate changes. the problem is the rate of change. In the last glacial/interglacial cycles the CO2 of the atmosphere never rose above 300ppm and the rate of change was less than 50ppm every 200 years. Not we have raised the CO2 of the atmosphere by 100 ppm in less than 100 years

Why are you posting reconstructions of deep time like it has any relevance? The data points in that graph are tens of millions of years apart and reconstruct cycles far larger than the ones active today. Not to mention the the planet was under completely different tectonic and oceanic regimes.
