You said that before but never supported you claim or contended with the fact that the Industrial revolution probably accounted for temp rising. i.e. we were putting co2 into the atmosphere in this period. The little ice age was only a localised event - not an ice age really.
Had the warming trend been associated with an impact of the little ice age you would believe that temp would rise to pre little ice age levels and not many times greater as we have now.
If you want to argue that Co2 is increasing because temp is increasing and not the other way around what do you base this belief on.
Note: science is pretty much unanimous on the point that greenhouse gasses cause warming - even the climate change sceptics know that this is true.
My friend your arrogance precedes your ignorance the chart has been posted for you to see, go back and have a look, atmospheric CO2 yearly increases fall in line with Earth heating up and natural sinks emitting more CO2 into the atmosphere.
The trend doesn't follow mans emissions which are too small to make any difference.
NO medieval warm period was GLOBAL and your arrogance precedes your ignorance.
The Medieval warm period was global.
You believe in science by consensus well then here you go.
You wont hear about these papers on sceptical science....

You put a lot of focus on the medieval period being real when it is in fact in significant doubt, either way it likely has not a lot to do with global warming.
In a nut shell there was once close to consensus that both the medieval warm period and the little ice age were both localised events, there were good reasons for this belief at the time.
More recently there has been evidence that there were warm and cool periods in the southern hemisphere as well as the northern. This has tended to swing the argument back to a position that they may have been global events.
The problem that still exists is that the time lines for these events seem to have been different. i.e the warn and cool periods in the northern hemisphere did not occur at the same time as in the south. This puts a question make back on the whole topic. However the causes are known and irrelevant to what we see today. Just more mud in the water to distract from the science.
