Demand Investigation of the UAH Shooting!

Guest opinion by Leo Goldstein Like everyone here, I am outraged by the terrorist attack of Dr. John Christy’s office at the University of Alabama (UAH) that followed the so-called “March for Science” (the MfS) where third-sort actors and copywriters pretended to be scientists. I share Dr. Roy Spencer’s frustration about the unwillingness of the…

25 Years of Monitoring Global Temperatures from Satellites and an Interview with Christy and Spencer of UAH

Guest Post by Bob Tisdale It’s been 25 years since Spencer and Christy of the University of Alabama at Huntsvillle published their 1990 paper Precise Monitoring of Global Temperature Trends from Satellites.  The abstract reads (my boldface): Passive microwave radiometry from satellites provides more precise atmospheric temperature information than that obtained from the relatively sparse…

RSS and UAH “Meteorological Annual Mean” (December to November) Global Temperatures Fall Far Short of Record Highs in 2014…

…And what we might expect from the GISS, NCDC and UKMO products. Guest Post by Bob Tisdale Alarmists from around the globe are awaiting the global temperature product update from GISS, which should be released sometime around the 15th of this month. As a separate listing, see the data page here, GISS provides the annual-average…

UAH Global Temperature Anomaly Down by .12C in February

UAH Global Temperature Update for February 2014: +0.17 deg. C (Note, my original headline number was unintentionally misleading, using a percentage to illustrate the drop rather that the absolute number. While the calculation was correct, it gave an impression of overall magnitude across the entire scale rather than the month to month change. It has…
