Climate change and global warming leads to endosymbiotic archaeal growth and alteration in brain structure and function. The endosymbiotic archaea have got magnetoperception and quantal perception of low level of EMF producing brain changes resulting in frontal cortical atrophy and cerebellar dominance. This produces the syndrome of epidemic cerebellar cognitive disorder with adult onset autism like presentation. This results in impulsive behaviour and surrealistic experience. The adult onset cerebellar cognitive disorder with autistic presentation leads to social withdrawal and agarophobia. This results in lack of social communication, empathy, compassion and affection leading to an epidemic of loneliness. The endosymbiotic neuronal archaeal overgrowth leads to a cerebellar cognitive affective disorder and adult onset autistic phenotype. There is lack of social communication, empathy, compassion and affection. This is replaced by selfishness, greed and a culture of evil. This results in a civilization of tribe adult onset autistic phenotypes without any social skills or civil responsibility. A culture of greed, selfishness and irrationality dominates the world.
