Searching for the Logic of Ignoring Earth’s Global Physical Conditions

Knowledge deficiencies and ignorance content relating to critical physical conditions of earth in glacial-interglacial cycles areanalyzed from the point of view of whether human societies are capable of adapting and dealing with radical climate change indistant future. Amplified Milankovitch theory and canopied earth theory of glacial-interglacial cycles provide conflicting signals,one seeing the current interglacial lengthened by human-induced climate change giving the human societies ample time to preparefor the next glacial and the other seeing the arrival of the next glacial to be independent of human activities and thus posing asupreme risk to unprepared human societies. Foundational analysis indicates little difference between the ancient and modernhumans reacting to glacial-interglacial cycles. Both, preoccupied with daily requirements of life fail to prepare to address theirknowledge deficiencies of global physical conditions and thus expose individuals and societies to immense risk without adaptivepossibilities.
