Islam and child marriage are inter connected, CO2 has nothing to do with either.
Only in the mind of a liberal could there be ANY interconnection between “global warming” (which may or may not be somehow connected to the levels to carbon dioxide in the atmosphere) and child marriage. Child marriage is a perversion of the tribal prerogatives to maintain order forcefully, by directing that this be done to appease certain tensions among the factions of the tribe. Arranged marriages of pre-adolescents are not a mark of high civilization.
