WUWT
I had naively assumed that after the publication of Menne (2009),
that USHCN trends published after 2009 would remain fixed because data
had been quality controlled for all known changes in location and
instrumentation and further homogenized whenever Menne’s algorithm
assumed a changing trend might not be natural. Anthony Watts, myself and many others have questioned the distortions created by homogenization and have warned about resulting warming biases. .......The bizarre consequences of USHCN’s monthly homogenization adjustments
are seen by comparing changes in Death Valley’s maximum temperature
trends over the past 2 years (solid black line). Adjustments were
inflicted despite the fact the data had been quality controlled and
adjusted several years before. ......By what possible logic, would 2 years of additional data suddenly
reverse a cooling trend since the 30s and create a warming trend? I
suggest we need to ask Congress for a full investigation. (Hat tip to
Miesler) .......Although there is no excuse for the lies, distortions and rudeness
posted by Mielser or Slandering Sou, I must sympathize to a limited
degree. Their delusions have been supported by bad science from the
USHCN and elsewhere, and when skeptics reveal the truth, it surely
drives them mad."
