Midieval Warm Period

Are we warmer now than in the Midieval Warm Period?  Or, is it colder?  I've found a chart from the IPCC that shows it was warmer then than now:

So, if that has changed, what data changed, or was it massaged because it was incorrect?  Help me out here!  I don't know what to believe.  Is global warming getting out of control, or are we slowly returning to a warmer temperature that we are supposed to be at?

How can I get my hands on the raw data for all this?
