Again I ask:
WHY DO WE NOT SEE THIS SORT OF INFORMATION IN WHAT IS
SUPPOSED
TO BE THE ENVIRONMENT MRB?
Anyone else think that the lack of technical/scientific posts in
Environment,
Economics and Finance and
Health and Welfare is dragging down the SEO ranking, the visibility, of OzPolitic?
Even Food could do a lot more.
Well talking about Berkley Earth, which is not scientific and expecting quality from it, is itself unscientific.
You see a GLOBAL temperature needs input from around the GLOBE. Now we know Sea Surface temperatures, prior to 2004, Argo buoys were "mostly made up", according to Phil Jones, formerly of CRU Anglia.
now Berkley Earth have this to say -
" This file contains a detailed summary of the changes in Earth's global average surface temperature estimated by combining the new high-resolution Berkeley Earth land-surface temperature field with a reinterpolated version of the HadSST4 ocean temperature field. "

monthly.txt[/url]
And BEST Berkley Earth says "The Berkeley Earth project provides a set of historical temperature products consisting of estimates of the monthly mean of average, maximum and minimum surface air temperature anomaly over land (Rohde et al., 2013a,b), as well as a pair of blended land-ocean products (Cowtan et al., 2015, supporting information) which provide near global coverage by combining land air temperatures with the HadSST3 sea surface temperature reconstruction (Kennedy et al., 2011a,b)."
So estimates of anomalies and averages. What could possibly go wrong?

Also NH stations have dropped from 3000 in 1950 to about 2000 today. SH stations have only dropped from 800 max to 600.
