At this point, SZ with all due respect, I have to figure that if you have put up the 'evidence,' (like the bit about the medieval warming period only affecting Europe) I figure that it is automatically suspect. I have to check it all out, especially when you do not (as you did not with the graph you provided) give any references or sources.
And you did NOT pay attention to the video, quite obviously....
But here...among other problems, try this:
Global Warming Bombshell
From an author who states, IN THE ARTICLE TO WHICH THIS IS A LINK, he states:
If you are concerned about global warming (as I am) and think that human-created carbon dioxide may contribute (as I do), then you still should agree that we are much better off having broken the hockey stick. Misinformation can do real harm, because it distorts predictions. Suppose, for example, that future measurements in the years 2005-2015 show a clear and distinct globalcooling trend. (It could happen.) If we mistakenly took the hockey stick seriously–that is, if we believed that natural fluctuations in climate are small–then we might conclude (mistakenly) that the cooling could not be just a random fluctuation on top of a long-term warming trend, since according to the hockey stick, such fluctuations are negligible. And that might lead in turn to the mistaken conclusion that global warming predictions are a lot of hooey. If, on the other hand, we reject the hockey stick, and recognize that natural fluctuations can be large, then we will not be misled by a few years of random cooling.
A phony hockey stick is more dangerous than a broken one–if we know it is broken. It is our responsibility as scientists to look at the data in an unbiased way, and draw whatever conclusions follow. When we discover a mistake, we admit it, learn from it, and perhaps discover once again the value of caution.
The thing is, Mann's 'hocky stick' HAS been proven to be inaccurate, and as for whether 'that' is the 'hockey stick graph..."
Here is Mann's "hockey stick" graph.
Hmnn. I can see that graph when I upload it, but I can't see it when I look at the post once submitted.
Try this (I hope)

Amazing how much it looks like the one you put up....and for which, again, you provide NO reference or source.
