So tell me in the past 2 million years have there been any 200 year periods where the temps were warmer than they are today?
Yes, there have been. About 120 thousand years ago, the CO2 stood at 300 ppm for a couple thousand years, and the temperatures were warmer, and the sea level about 3 to 6 meters higher.
It takes time for the environment to react to the input of heat that the GHGs are creating. However, the speed at which the globe is reacting at present exceeds the speed with which it reacted in prior geological times to rapid GHG input. The times just pror to some very serious extinction events.
