CRUT4 warms the USA by ~0.3 degrees C in 1997 compared to CRUT3
April 8th, 2012 by Warwick HughesWhile working on my benchmarking study on April 5th, 2012 – I noticed a clearcut step change in 1997 between CRUT3 and CRUT4 over much of north America.
I have portrayed this in map form to understand better what the CRU team has done in the various grid boxes.
It seems that for most of the USA grid boxes CRUT4 is warmer by one division on the temperature anomaly scale (0.3 degrees C). But note the grid box for Los Angeles has warmed by 3 divisions or ~1 degree C.
I am intrigued that the CRUT team makes such large adjustments over the USA – home to so many climate researchers. In 2006 I found amazing agreement over the USA between HadCRUT2 and satellite lower troposphere temperature data. I assumed that was one area of the globe where the CRUT team had little “wriggle-room” to adjust data. Not so it seems.
Anyway, I will do more on the subject later but wanted to get this surprising result out there. Who was it said something like – “…the future is known – it is the past that changes…”

The publications at Principia Scientific International show why carbon dioxide has absolutely no effect on climate, so sensitivity is zero. See, for example, my peer-reviewed paper Radiated Energy and the Second Law of Thermodynamics on the site.
I am proud to be an active member of PSI and, as such, I am in daily email contact with many of these main stream scientists, including professors and PhD’s in various disciplines such as physics, applied mathematics, chemistry, climatology and astro physics. The numbers are approaching 40, including well known new members just announced.
What I write are not just my theories. We are all in agreement that standard physics and empirical results back us up.
