Hi Marco, all  - 

The lack of results from the new Europen Greenland ice
cores is disturbing, given the gross physical remains
from impacts of fragments of Comet Encke, the
contemporary text accounts of climate collapses, and
the tree ring evidence.

Which archeological excavation was that, Marco? What
were the results?

Actually, no atmospheric burst are necessary,
particularly in the case of comets, where there
already is a dust stream.

Yes, it should, and it is - in the tree rings.  The
question now is why it is not in the ice cores.

Could this be due to processsing errors, in other
words errors in technique?  They have reported that
isotopes were being used to measure sunspot activity
as well, and could this have thrown off the dust
measurements? 

I am waiting for further information on how the ice
cores were processed, and the release of the raw data.

good hunting,
EP
