Making a muckle out of a mickle
My heading above is in Scots. It means making something big out of something little. Its the expression that leapt to mind when reading "More errors identified in contrarian climate scientists' temperature estimates" from diehard Warmist, Prof. John Abraham. He has been refuted many times so I see no point in reproducing his effusion, let alone fisking it. His modus operandi is to present as established fact Warmist beliefs, with no supporting references to substantiate them. He has to do that. Most of them are at best controversial if not outright false.
Like most Warmists he has to clutch at any straw that might support his beliefs. And he has found a recent paper that appears to have given him an erection. I reproduce the abstract below.
The paper is not even about global temperatures. It is about the Arctic only. It reports minor disagreements in the way the satellite data for the Arctic is presented. It does not address the fact that the various methods concerned give global temperatures that correlate around .90 and that the disagreements in reported temperatures are in hundredths of a degree. But, most importantly, all the measurements show the same trend -- temperatures flatlined for many years with the only rise coinciding with the recent El Nino weather oscillation. Naught for the comfort of Warmists there.
A Comparative Analysis of Data Derived from Orbiting MSU/AMSU Instruments
R. Eric Swanson
Spencer and Christy of the University of Alabama in Huntsville (UAH) recently introduced a new method to process MSU/AMSU satellite brightness temperature data with their version 6 (v6) data. A comparison of UAH v6 north polar lower stratospheric (TLS) data with that from Remote Sensing Systems (RSS) is presented, indicating a possible bias between 1986 and 1988. Comparing UAH and NOAA Center for Satellite Applications and Research (NOAA) TLS data produces a similar result. An additional analysis utilizing midtropospheric (TMT) data also found a similar bias. Comparing the NOAA TMT data for the May 2016 release against UAH and RSS TMT evidenced another excursion, dated at the middle of 2005, that was corrected in later releases. These comparisons reinforce the concerns expressed by other analysts regarding the merging procedure for UAH v6, repeating similar concerns regarding the earlier UAH v5 products. Any biases in the UAH, RSS, or STAR products would impact the trends calculated for these products and could explain the differences between these trends. Biases in the UAH series would also impact the UAH TLTv6 lower-troposphere product, which is a linear combination of the UAH TMT, tropopause temperature (TTP), and TLS series.
