Antarctic Land Surface Temperature (part 5)
In this article I take a look at GHCN-M land surface temperature records for Antarctic bases and unearth evidence of BADWARM (Base Development Warming)
In part 4 of this series we took a look at data collection at Orcadas base, this offering the longest running land surface temperature series for Antarctica. Although nice and shiny and supportive of the alarmist narrative, we discovered a few hidden secrets and came to the conclusion that data collection at Orcadas since 2005 is rather poor in comparison to that undertaken 1903 – 2004, being loaded with observation bias owing to equipment failure during the coldest months of the year. We also noted zero warming from 1904 – 1980, after which there is a sudden notable trend estimated at +2.19°C per century (p=0.02). Questions were raised about base development affecting measurement (urban heat island effect) among other things, as well as accuracy of measurement itself in such extreme conditions.
Measurement of land surface temperature down at the coldest spot on Earth is obviously fraught with difficulties, but these are glossed over if the alarmist narrative is supported. Back in part…
