Climate hypocrites - My letter in today's Australian., page-33

That graph has been flogged around like a beaten-up rag doll for many years now.Been de-bunked many times.
Many of the data points were collected from Aerodromes which have since developed into Airports.Concrete structures,bitumen carparks which act as a heat sink.
Data from less developed Equatorial regions were not included in the study as it did not support the narrative.
Globally the period between 1860-1880 was colder than normal.I note that many climate change graphs start from 1880 onwards.
Historically,I would be much more concerned with the prospect of Global cooling.
