Very nice!

Rather detracting from the value of the image is the fact that the
vertical extent of the colored bars is not explained in any detail. It
"feels like" some sort of uncertainty measure (older years indeed do
have wider bars) but the source of the data and the analysis
represented by the bars should be explained somewhere accessible from
the page. It would be dramatically more useful that way.

That said, the image itself is a very nice illustration of Tufte-esque
principles, and it makes the actual situation (right, the actual
warming trend) much more cognitively accessible than does the usual
time series.

I have said as much on my blog, by the way.
