I think it would be prudent for us to take a step back and note that this revelation of what has been denoted as "data change" is relatively recent, and has not yet had enough time to be properly addressed by the parties involved, or rather normal people doing normal research. After looking at the two different data sets for the adjusted data, it's obvious that there is a discrepancy. Also one can note the addition of data sets that were not previously included.
Anyways, i'd like to see how this plays out over the next couple of months, considering conspiracy theorists are usually not on the forefront of experts' concerns. Also, considering how the first two graphs are placed to be deceptively misleading, it would not be a surprise to see these claims fall flat on their faces, just as those who jumped at "Climategate" did.
