Greenland Ice Sheet

Tim Cullen has come up with two more posts on how the ice cores were calculated - which will not please the defenders of the faith ... see .. and the the great greenland snow job 08 (an no doubt he has not finished yet). I don't pretend to know if his criticism is valid or not but it is interesting to know a bit about how such calculations are made. Simply picking out pieces of odd data and criticising that is not of course enough to rest a case for bunkum.

radioactive decay rates

At face value this new paper at Astroparticle Physics 55 (2014) seems to be a case of circling the wagons, a sort of confirmation of the consensus view. Readers may like to make up their own minds by going to the press release - see

Stretching the Dark Age

At ... the Greek Bronze Age ended 100 years earlier than thought according to a Bayesian averaging of C14 dates undertaken in a recent study. It was a fairly comprehensive exercise by the sound of it - but there was perhaps a nefarious undercurrent at the same time as it was designed to fit in with the chronology advocated by those who would date the Thera eruption to the low growth tree ring event (and ice core acidity anomaly) around 1625BC.

Volcanic Fingerprints

Each volcanic eruption gives birth to a unique signature in the composition of the ash and in the glass shards that lodge within soil. Even eruptions from the same volcano have different chemical elements, even down to the shape of the shards. A volcano in Alaska that blew in the 9th century AD has a distinctly high chlorine content and this has helped identify its fingerprint across Europe and northern N America - see The research was done at Queens University Belfash.

Calendars and Sea Levels

Yes, back to another post at ... which on this occasion takes a look at Illig, Niemitz, and Hunnivari, who have each produced a different version of an AD revision to that of Gunnar Heinsohn. I'm not sure to what extent the arguments are valid but here we go - starting with Zoltan Hunnivari, who was unable to find a suitable eclipse to fit the prodigy seen on the death of Augustus Caesar in AD14. This supposes that such a prodigy did occur and even if it did that it was an eclipse (or rather an annular eclipse).

Ice cores, tree rings, radiocarbon ... in the News

Doug Keenan refers Bob Porter to an article in the Journal of Geophysics Research 117 (2012), 'Holocene tephras highlight complexity of volcanic signals in Greenland ice cores' at NewChronology [at] yahoogroups [dot] com


At ... Tim Cullen introduces the concept of catastrophic outliers in dendro constructs that are artefacts of the smoothing process within calibration of tree rings and C14. It is a remarkable insight into what may or may not be what happened during the construction of the modern dating system so faithfully relied upon by archaeologists, historians, and various others - including anthropologists (in the previous post).

Bristlecone pines and Time

At .. Tim Cullen gives an opinion on the process involved where the C14 model was wedded to the bristlecone pine dendrochronology, an odd sort of marraige of convenience in that C14 was rocking after revelations that dates produced by the methodology not as reliable as claimed - and did not meet the requirements of the orthodox Egyptology. It is now well known that there have been a series of plateaus in C14 that mess up the reliability of the methodology at those points in time.

Mankind in Amnesia

The headline to this was decided because at the end of the piece he has a picture of Velikovsky's book jacket, Mankind in Amnesia. Andrew Fitts, a recently joined member of the society, is particularly interested in this aspect of Velikovsky's work - which we will all find out about in the course of time. The link is again to a posting by Tim Cullen at ... and is a lovely post that will resonate with Velikovskians, whatever their favoured subject.

Gaps in tree rings sequences

Tim Cullen appears to continue to be impressed by Gunnar Heinsohn's articles at (and another one has been posted over the last couple of days). Hence, in this look at the dendrochronology process he is looking for the possibility of an error in the region of 700 years of time being taken out of the first millennium AD. Therefore, he has an agenda. I'm not knocking it - just saying. What he has discovered is that there are two gaps in the sequences - one in the first millennium BC (at the point of the C14 curve) and the other in the first millennium AD.
