Facing an accelerating implosion of faith in the anthropogenic (man-made) global warming (AGW) theory due in part to satellite data showing more than 18 years of no warming — the great “pause” or “hiatus,” as some put it — one of the satellite data sets has now been adjusted to show a slight increase in temperatures over the last two decades. Global-warming theorists on the government dole celebrated the news, speculating that it might herald the end of skepticism over their controversial theory and even what particularly rabid warmists refer to as “climate denial.” However, experts and scientists warned climate alarmists to cool it — especially because the “adjusted” data is now significantly different than other, unmanipulated temperature data sets. There appear to be big problems with the adjustments, too, experts in satellite temperature data said.
The adjusted data set in question comes from Remote Sensing Systems (RSS), satellites put into orbit by NASA but now overseen by chief RSS climate scientist Carl Mears in Santa Rosa, California. The new numbers, which were recently adjusted, purport to show about 0.125 degrees Celsius of warming every 10 years. That is radically more than the 0.078 Celsius per decade — a statistically insignificant figure — that the RSS data set showed before being “adjusted.” The new numbers from RSS also show radically higher temperature increases than other satellite data, such as the numbers from the University of Alabama at Huntsville’s data set (UAH). Examining the alleged warming over the tropics, for example, the new adjusted RSS data shows a rate of warming almost five times larger than UAH data, analysts said.
Scientists at UAH, including Dr. Roy Spencer, former senior climate scientist at NASA, compared the new RSS results with the data collected by UAH satellites. In comments on his own website and at climate-focused outlets, Spencer said there had been “spurious warming” added into the new RSS data — a problem that UAH data does not have. He blamed the spurious warming in the adjusted RSS data set on the RSS scientists failing to correct for discrepancies between more accurate temperature data-gathering instruments and data gathered by older, poorly calibrated instruments that have drifted from their original orbit. “I suspect Carl Mears [with RSS] grew tired of global warming ‘denialists’ using the RSS satellite data to demonstrate an 18-year ‘pause,’” Spencer was quoted as saying by the Daily Caller. “So, now that problem is solved.”
