COMPARING SURFACE TEMPERATURE RECORDS WITH THE SATELLITE RECORD

The following article is available here by Warwick hughes. I have reproduced it, as it is rather disjointed on the original site. What is interesting here is not only that there is now such a difference between the trends for the land and satellite data, but how the land data has been continually altered as each new data set has been compiled.

"Half a decade back you could make the case that trends 1979-2005 in the old land only CRUTem2 were not too different from University of Alabama at Huntsville AMSU satellite based lower troposphere trends."

LAND ONLY SURFACE TEMPERATURE RECORDS COMPARED WITH SATELLITE TEMPERATURES. (All trends in Degrees C per decade.)


1979 - 2005

             UAH AMSU     CRUTem2    CRUTem3     CRUTem4

Global         0.16                0.17              0.24               0.28

N Hem        0.23                0.25              0.33               0.35

S Hem        0.03                0.10              0.15               0.14

1979 – 2010

Global        0.18                                     0.22               0.27

N Hem       0.24                                     0.32               0.34

S Hem       0.06                                     0.12               0.13


"The introduction of the UKMet Office dominated CRUTem3 in 2006 saw the land trends 1979-2005 blow out and the just introduced CRUTem4 of Dr Phil Jones et al has increased the warming trend 1979-2010 again over the earlier CRUTems and satellites."

So the next time somebody says to you, “…well anyway the satellite temperature trends agree with the surface…”..

You should ask them to check the numbers because it simply is not so anymore.
