About 400,000 years of data, extracted from the Antarctic Vostok ice-core, were submitted to statistical analyses.  The results suggest that the duration and thermal stability of the current interglacial are significantly larger than those of the four previous ones are.  Hence, the results could not be contributed to natural variables.  This could support the hypothesis that the current interglacial period changed some time ago into a glacial period, while artificial global warming has compensated for that natural global cooling.  During a glacial period, the average global atmospheric temperature could decrease with about 10.0 °C.  This would reduce the global food supply; threaten the global infrastructure; and force billions of people to migrate back towards the equator.  Therefore, artificial global warming could be the solution for natural glacial cooling.  Further research of this topic is crucial.
