this is not a question of whether global warming is real or not.
This is a question to all of those people who 'dispute' it.

Generally, most movements in life have to come from somewhere; that is, there is a context in which they arise. For instance, the 'civil rights' movements came from the oppression of the blacks in this country. But some other people say that this movement was a result of efforts by a group of 'liberal' bankers; who were not able to control the system of the south where there was this 'segregation'.

Whatever; its the point that matters, not the specifics.

So, if global warming is a scam of global proportions, then where does it eminate from? What historical context has given rise to this global warming; and if such, who are the ones leading the charge?
