modern climate observations, which likewise we are in no position to change.

climate variability, and that in order to understand
climate change along the Antarctic Peninsula, we need to understand the broader
climate connections with the rest of the planet.

In this second article we re-examine related events concerning the 1850/1880 CRU / Giss temperature records, and then pay particular attention to the reliability of those readings that have become the basis of our
modern climate industry, examine those who carried out the original
observations, and look at the circumstances under which data was collected.
But the
modern range of estimates is based on more lines of evidence and better methodology (analyzing recent
observations, better models, and investigations into pre-human
climate conditions), which give about the same picture for now.
I came to this domain not through any
climate route but from the
observation that cultural mechanisms dominate, and my aim is to make these mechanisms clearer as they occur in many domains (with CC as a great example, because most of it's life is played out in
