A narrative of climate states as represented through cultural use and re-use of stone in local societies

As a climate physicist  - I’m conscious we can use the evidence in the environment around us to help attribute and understand how we adapt to environmental changes. The stones in our vicinities, their use and the geo weathering over long time periods gives us clues to older indigenous societies and the choices made in their cultural epochs.  In this discussion I’ll discuss how society changes over the past 2000 years can be a) assessed using formal methods of signal analysis using paleo and instrumental data record, b) interpreted through the clues provided by stone use/ re-use and weathering evidence and c) known alterations to the climate dynamics in given localities. Examples will be drawn from the localities influenced by long term Pacific and Atlantic climate processes, and the interpretation of how society choices have functioned through their use of stone will be debated.
