Here's a fun chart.

While that's undoubtedly a cute chart, it's extraordinarily misleading. Let's look at a more detailed chart compiled from several sources:

1000_Year_Temperature_Comparison.png


From here

This image is a comparison of 10 different published reconstructions of mean temperature changes during the last 1000 years. More recent reconstructions are plotted towards the front and in redder colors, older reconstructions appear towards the back and in bluer colors. An instrumental history of temperature is also shown in black. The medieval warm period and little ice age are labeled at roughly the times when they are historically believed to occur, though it is still disputed whether these were truly global or only regional events. The single, unsmoothed annual value for 2004 is also shown for comparison.
 
I'm afraid neither one of those charts are valid. Since this is no longer a discussion of the topic, thread closed.
