ICR's Aardsma wrote that article over the objections of two men who were familiar with Barry Setterfield's work and saw the Aardsma was condensing the graph so much as to erase data point differences, among other things. When this was shown to him, he disregarded the comments and submitted his article to ICR anyway.
Responses to Aardsma were published in Galilean Electrodynamics, authored by Lambert Dolphin, a physicist, and Alan Montgomery, a statistician. In the meantime, Setterfield has also responded to the nonsense on Talk Origins. The links are below:

One note, Aineo, in Einstein's equation E=mc^2, it was shown in the 1987 paper that m is proportional to 1/c^2, so that with all changes in c, energy is conserved. http://www.setterfield.org/report/report.html#4b
The data shows that this is, in fact, the case, and not simply a theory pulled out of thin air. Again I would refer you to the charts here:

God bless.
