Re: Willis Eschenbach (#12),
Willis and Bernie -
I enlarged the image and get three impressions:
1.) Looking at other years and the data traces vs the smoothed out curve, it appears that this asymmetry is common on this graph.
2.) It does not appear that the data line (grey) extends up past the top of the image.
3.) It does appear that the data line (grey) has more width above the line than below, so I speculate that the data line above the black line represents more data points above than below. The negative spikes are sharper, implying single points, whereas the positive spikes are more rounded.

My overall impression is that there are simply more positive values than negative ones, implying the positive spikes are multiple data points; i.e., there is some kind of a dwell on the positive side.

It is too indistinct to tell for sure, but that is my impression.

The data, of course, are the data. I am just adding to the discussion (way after the earlier comments) about the image.

This stuff is practically Greek to me, but thank you Steve for finding the problem. I am currently experiencing a heated argument with another poster on another website concerning Global warming and the validity of the IPCC report and its followers and their agendas, etc. Whilst I am a mere average citizen, he is a reporter for a newspaper in Canada and his ego knows no bounds. I wish some of you smart guys could come and put him to sleep. It would help. Thanks for the interesting comments.
