Pause retroactively erased?! Even Warmed Up Satellite Temperature Data Isn’t Close To What Climate Models Predicted
Newly updated satellite-derived temperature data shows much more warming in the bulk atmosphere than previous data, but shows the Earth’s atmosphere is still cooler than most climate models predicted.
“It’s not that big a change, and it’s still controversial and new,” Chip Knappenberger, a climate scientist at the libertarian Cato Institute, told The Daily Caller News Foundation. “It’s still not coming close to explaining the discrepancy between the models and the observations.”
A new version of Remote Sensing Systems (RSS) satellite data, run by climate scientists Carl Mears Frank Wentz out of Northern California, shows much more warming than other satellite and weather balloon measures of the mid-troposphere.
RSS data now shows 0.125 degrees Celsius of warming per decade — a great deal more than the 0.078 degrees per decade it previously showed. NASA’s top climate scientist even suggested this could mean the end of the more than 18-year “pause” in the RSS data.
Skeptics took notice of the change to the RSS warming trend and pointed out that Mears and Wentz did not correct for discrepancies between two different National Oceanic and Atmospheric Administration satellites relied on to collect data which is then converted into temperature readings.
“We’ve looked at their new results versus our data, and it does appear that the new warming they’ve ‘found’ is just spurious warming in the old (poorly-calibrated, and orbit time-drifting) NOAA-14 MSU instrument, which they leave in the data analysis,” Roy Spencer, a climatologist at the University of Alabama in Huntsville, told TheDCNF.
“We remove that spurious warming since it disagrees with the newer (better calibrated, non-drifting) NOAA-15 AMSU instrument flying at the same time,” Spencer said.
Mears also wrote on his website he was getting a lot of questions from those worried “denialists” were using his satellite data to cast doubt on global warming, which has some skeptics worried he’s looking for an excuse to find warming.
“I suspect Carl Mears grew tired of global warming ‘denialists’ using the RSS satellite data to demonstrate an 18-year ‘pause,’” Spencer said. “So, now that problem is solved.”
Spencer went into further detail about why he thinks Mears’ new data is adjusting good data upwards to meet bad data in a blog post Friday.
Mears, however, argued the “spurious warming” in the new data is from overlapping satellite coverage of the atmosphere. Even if they wanted to make the correction Spencer argues for, Mears says it doesn’t make much of a difference in the overall trend.
