Abstract

Climate deterioration at around the time of the Bronze Age/Iron Age
transition has for long been argued to have resulted in upland
abandonment in northern and western Britain, and recent research has
provided evidence that a major climate downturn from 850 cal BC caused
settlement abandonment in western Europe and potentially worldwide.

THAT is pure bull*** for a starter!


It
is, however, unclear to what extent only ?marginal? sites were
affected, due to the lack of any systematic attempt to view the
evidence for settlement and land-use change across a range of
landscape types with differing sensitivities to environmental change.

Aha..... so if the effect on "marginal" settlements are unknown, how
can a claim even be posed to say anything caused "settlement
abandonment in western Europe and potentially worldwide"!

This paper addresses this issue by an evaluation of 75 pollen
sequences spanning the late Bronze Age and early Iron Age in Britain
to assess whether climatic deterioration was sufficient to cause
widespread land abandonment. The results provide no evidence for
wholesale land-use change at this time; the overall picture is one of
continuity of land use or even increased agricultural activity. There
are, however, hints of regional variability, with a greater tendency
to abandonment of upland areas in Wales, and signs of woodland
regeneration in agriculturally productive areas of lowland central
southern England. The latter pattern may reflect a combination of
rising ground-water levels affecting local land-use in the immediate
vicinity of the mires which provide the source of the pollen data,
against a backdrop of regional-scale social and economic changes at
the Bronze Age-Iron Age transition.

I draw your attention to this statement:
http://www.ipcc.ch/pub/wg1TARtechsum.pdf

"A report accepted by Working Group I of the IPCC but not approved in
detail" - that is to say they have received the report as worthy of
discussion.

IPPCC = Intergovernmental Panel on Climate Change

So it is a "religion" we are looking at once more! They too have
resorted to showing a "graph" from 1860 on to "demonstrate" the so
called "global warming" - something just after the end of the little
ice age.... aha.... and this is the most common ploy used to "prove"
their "case".

Your response might make more sense if I could see how it relates to
the article I cited.
