That is .625 millionths of the age of the earth.  Our species will be extraordinarily lucky if we don’t make ourselves extinct in the next 4000 years… certainly past the next ice age.  Mother Nature will have all but eradicated evidence of us having been here within 4000 years after that. If my prediction is true, our total dwell time on earth will be about 1.9 millionths of the age of the earth… after we have been erased.

We should note that during the last 3 interglacial (warm) periods, the average high temperatures were higher than in the present (Holocene) interglacial period. Indeed the Klein Graph is so insignificant, that we cannot represent it with a visible line.

Political expediency informs the ignorant that we are overheating the earth.  HOWEVER, look at the real trend of our current interglacial period.  Real science indicates that the descent into another glacial period has begun.

Let us bring into context the CO₂ concentrations of the glacial periods of the last 8K (eight hundred thousand) years.  Please note that CO₂ concentrations were higher than the present in the Sangamon and in the Yarmouth I and II interglacial periods. (To be sure, mankind was lighting only campfires and the occasional forest fire.)

Despite the misrepresentation of “consensus”, AGW is NOT an accepted theory among REAL scientists.
