Human metabolism and climate change can modulate brain function and the organization of the social-cultural-political-linguistic world. Autistic savantic and psychopathic qualities help to define modern leadership. There is a singular lack of morality and ethics with pointed dedication to achieve selfish nationalistic and personal goals. The modern leadership is characterized by lack of conscience and amorality. 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 cerebellar dominance leads to impulsive behaviour contributing to aggression, violence, terrorism and criminality. Metabolism can regulate the socio-political-cultural-linguistic world.
