Why is it that you laugh at whatever I post even though it's backed by serious research and analysis, yet you post a graph depicting current temperatures are higher than the peak Medieval Warming Period without specifying an original author? Then you use the same graph to blame the industrial revolution back in the late 1700s/early 1800s in England for the global warming. Again without any references to studies alluding to such an idea. No amount of "LOL"'s here would be sufficient to make my point. Please post references so I can study them. I'm eager to do so.
