I cut this one out of a script to a paleontology-reading I had.
It's not the best either, because the image was pretty small in the script and I stretched the image a bit to enlarge the area which interests us. Unfortunately there is no good y-axis marking in this one aswell, but atleast we have some absolute values to go by and not just relative values as in the other graph.
note, that the time axis is variable, as indicated - the various lines are different results you get from analysis of several ice cores - the black line is the absolute average of those ice cores - there is a small line through the holocene period marking the 14.1°C degrees global average temperature, which we see as the (current) climate optimum
edit: ah screw that graph - I found a better one - the one you had, but in a form which is useful
as we can see the data for 2004 is far above what the average curve says (and above the average of the climatic optimum 8-4 thousend years before - the 14.1°C from the other graph) - the other lines again are results from the different ice cores which were taken - unfortunately I don't know what time the "recent proxies" graph covers, but it made sense, if it was the last 200 years
