Those same scientists produced the data that made this possible. The same predictions they've been making since the 70s, the same ones Al Gore et al. built a financial empire on... did not come true, and are woefully wrong.

Pay attention to both scales. Did humans have greater climate change ability than we have now, in the past, but then suddenly stopped? Notice the range labeled "mini ice age" covers a time period during an extended period of abnormally low solar activity (with the Spörer and Maunder minimums happening during this period).

Edit: Also, sorry, I couldn't find better URLs for these images, Google isn't cooperating today.

Again I'm no expert, but some Googling states that the medieval was indeed possibly hotter at some places on Earth but that this was due to difference in solar radiation and absence of vulcanic eruptions, factors that are not in play today.

On a more personal note, if a scientific consensus is not it, what kind of information would be able to convince you that man made global warming is real?
