Reliable? CRU, NASA, BEST, NOAA Land Temp Data Conflict By Up To 90% (0.8°C), Spawning ‘Large Uncertainty’

 
A new paper documents “remarkably different” land temperatures from one instrumental data set to another. In some regions there is as much as an 0.8°C conflict in recorded temperature anomalies for CRU, NASA, BEST, and NOAA. The relative temperature trend differences can reach 90% when comparing instrumental records. Consequently, the uncertainty in instrumental temperature trends — “0.097–0.305°C per decade for recent decades (i.e., 1981–2017)” —  is as large or larger than the alleged overall warming trend itself for this period.

In a just-published audit of the IPCC-preferred HadCRUT temperature data set, Dr. John McClean identified 70 problems that seriously compromise the reliability and accuracy of this IPCC-preferred instrumental record dating back to 1850.

Joanne Nova provides a summary of the main points from the paper, McLean’s Ph.D thesis.
