Earth itself is telling us there’s nothing to worry about in doubled, or even quadrupled, atmospheric CO2"

Readers may recall Pat Franks’s excellent essay on uncertainty in the temperature record. He emailed me about this new essay he posted on the Air Vent, with suggestions I cover it at WUWT, I regret it got lost in my firehose of daily email. Here it is now. – Anthony

In my recent “New Science of Climate Change” post here on Jeff’s tAV, the cosine fits to differences among the various GISS surface air temperature anomaly data sets were intriguing. So, I decided to see what, if anything, cosines might tell us about the surface air temperature anomaly trends themselves. It turned out they have a lot to reveal.
As a qualifier, regular tAV readers know that I’ve published on the amazing neglect of the systematic instrumental error present in the surface air temperature record It seems certain that surface air temperatures are so contaminated with systematic error – at least (+/-)0.5 C — that the global air temperature anomaly trends have no climatological meaning. I’ve done further work on this issue and, although the analysis is incomplete, so far it looks like the systematic instrumental error may be worse than we thought. J But that’s for another time.
The conservation and restoration of archaeological sites is the process of professionally protecting an archaeological site from further damage and restore it to a previous state. Archaeological sites require an extra level of care in regards to their conservation and restoration. Archaeology, even with thorough documentation, is a destructive force. This is because once a site has been even partially excavated, it cannot be put back the way it was, so to keep getting information from the site, it must be conserved to current best standards.
