Find a graph from someone who's not outright lying to you. GISP2 uses 1950 as "present", so that chart actually ends in 1855. Basically none of the anthropogenic rise in temperatures is viable on your graph. Also, conflating temperature anomalies in Greenland with global mean surface temperature isn't going to work well. Current temperatures are well above those in the periods you mention.

Here's the Marcott reconstruction:

Compare with GISSTEMP, which uses a similar baseline:

The Earth has warmed more over the last hundred years (+1.0C) than it cooled in the four thousand before that (-0.6C).
