So what caused global warming during the middle ages?
Warmers don't like to talk much about what the climate has been like over the course of the earth's history. One look at the climate history of the earth and the hand wringing hysterics of modern warmers is brought into sharp relief. Below is a graph that shows what the climate history of the earth looks like and where we are right now in relation to that past. As you can see the earth is, at present, quite cold when compared to its history which is to be expected since we are still in the fairly early stages of coming out of a deep ice age. Anyone with half a brain should be able to look at this graph and predict a long warming/cooling peiod with the overall trend being towards warming till such time as it is so warm that no ice exists on the earth......anywhere. The pattern has repeated over and over and over and there is no reason to suspect that it is not in the process of repeating again.
The high priests of AGW are perfectly aware of what the earth's climate history looks like and as such are perfectly aware of what the future climate is likely to be like. In the days of old, high priests, sorcers, magicians, prognosticators, shamans, conjurers, soothsayers, etc., posessed certain knowledge that the average person among the great unwashed didn't. Knowledge such as the ability to predict a lunar or solar eclipse, knowledge of the natural signs that were indicative of how productive the coming growing season may or may not be, knowledge of seasonal floods or droughts, etc.
Those old high priests used that knowledge to gain entrance into the places of power and to not only exert influence over the great unwashed, but to exert influence over the kings, queens, princes,
maharajah, and various royalty, aristocracy, and nobility upon whom their living, and very lives depended. They used this knowledge to extract fear, respect, and sacrifice from everyone within their sphere of influence and to convince them that they must change the way they lived their lives to avoid catastrophy. Sound familiar? Sadly, that is precisely the template being used at present by the high priests of anthropogenic climate change. They are taking advantage of the poor state of education here, and around the world and using knowledge that most people aren't aware of to extract fear, respect, and above all, sacrifice from everyone within their sphere of influence.
Had you lived in the time of the pharohs and were you able to show the great masses of people a seasonal chart describing the floods of the nile with decadal and longer patterns, how much respect do you believe the high priests who supposedly appeased the gods of the floods would have been able to command. If you could have distributed a chart showing past lunar and solar eclipses and accurately predicting those in the future, how much power could the shamans of the day have grabbed if everyone could predict an eclipse?
So hear is a chart showing what the climate of the earth has looked like back through the murky mists of time. Take a good look at it and tell me if you see anything scary there or a pattern that might indicate that the rise of man has somehow caused the climate to deviate from its eternal cycle. Tell me how a thinking person could look at this, taking note of where we are, at present, on the graph and put any creedence at all in the absolutely bogus claims being made by climate science. Ask PLC if he sees anything there that might cause him to think that man is causing anything within the climate that might be reasonably called unprecedented.
