Scientists Balk at ‘Hottest Year’ Claims: Ignores Satellites Showing 18 Year ‘Pause’

17th Jan 2015

UK Guardian: ‘Hottest Year’ Claim: 2014 officially the ‘hottest year’ on record US government scientists say – ‘Nasa and Noaa scientists report 2014 was 0.07F (0.04C) higher than previous records…The global average temperatures over land and sea surface for the year was 1.24F (0.69C) above the 20th century average, the National Oceanic and Atmospheric Administration (Noaa) and Nasa reported. The scientists said 2014 was 0.07F (0.04C) higher than the previous records set in 2005 and 2010.’

But scientists and climate skeptics are countering that the claims of “hottest year” are based on immeasurable temperature differences that are based on hundredths of a degree differences.

Climate Depot’s Marc Morano issued this statement: “There are dueling datasets. Surface temperature records and satellite records and they disagree. The satellites were set up to be “more accurate” than the surface records. See: Flashback: 1990 NASA Report: ‘Satellite analysis of upper atmosphere is more accurate, & should be adopted as the standard way to monitor temp change.’

Any temperature claim of “hottest  year” based on surface data is based on hundredths of a degree hotter than previous “hottest years”. This immeasurable difference is not even within the margin of error of temperature gauges. The claim of the “hottest year” is simply a political statement not based on temperature facts. “Hottest year” claims are based on minute fractions of a degree while ignoring satellite data showing Earth is continuing the 18 plus year ‘pause’ or ‘standstill’. See: The Great Pause lengthens again: Global temperature update: The Pause is now 18 years 3 months (219 months)

Claiming 2014 is the “hottest year” on record based on hundredths of a degree temperature difference is a fancy way of saying the global warming ‘pause’ is continuing.”

End Morano statement. (Morano was former staff of U.S. Senate Environment & Public Works Committee)

Even former NASA global warming chief scientist  James Hansen, the leading proponent of man-made global warming in the U.S., conceded in 2011 that the “hottest year” rankings are essentially meaningless. Hansen explained that 2010 differed from 2005 by less than 2 hundredths of a degree F (that’s 0.018F). “It’s not particularly important whether 2010, 2005, or 1998 was the hottest year on record,” Hansen admitted on January 13.

Climatologist Dr. Judith Curry, former chair of the school of earth and atmospheric sciences at Georgia Institute of Technology, had this to say about 2014 being the ‘hottest year’: “The ‘warmest year’ is noticeably missing in the satellite data sets of lower atmospheric temperatures,” Curry wrote on January 16. Curry predicts another decade of a global warming ‘pause’ or ‘hiatus’. “I’ve made my projection – global surface temperatures will remain mostly flat for at least another decade,” she eexplained

“With 2014 essentially tied with 2005 and 2010 for hottest year, this implies that there has been essentially no trend in warming over the past decade. This ‘almost’ record year does not help the growing discrepancy between the climate model projections and the surface temperature observations,” Curry told the Washington Post.

Curry continued: “Berkeley Earth (temperature analysis) sums it up well with this statement: ‘That is, of course, an indication that the Earth’s average temperature for the last decade has changed very little.’

Climatologist Dr. Pat Michaels, mocked the notion of the “hottest year.”  

“Whether or not a given year is a hundredth of a degree or so above a previous record is not the issue. What IS the issue is how observed temperatures compare to what has been forecast to happen,” Michaels said.

Michaels continued: “John Christy and Richard McNider, from University of Alabama (Huntsville) recently compared climate model projections to observed lower atmospheric temperatures as measured by two independent sources: satellites and weather balloons. They found that the average warming predicted to have occurred since 1979 (when the satellite data starts) is approximately three times larger than what is being observed.”

Climatologist Dr. John Christy, professor of atmospheric sciences, University of Alabama-Huntsville, noted satellites do not agree with “warmest year” claims.

“The satellite and balloon data of the deep atmosphere have 2014 in a cluster of warmish years well below the hottest two of 1998 and 2010″, Christy said.

“With the government agencies reporting that the surface temperature as highest ever, we have a puzzle. The puzzle is even more puzzling because theory (i.e. models) indicate the opposite should be occurring – greater warmth in the deep atmosphere than the surface. So, there are just many very basic and fundamental aspects of the global climate we have yet to comprehend.”

Climatologist Dr. Roger Pielke Sr., professor of atmospheric science, Colorado State University downplayed the accuracy of the surface temperature record.

“There remain significant uncertainties in the accuracy of the land portion of the surface temperature data, where we have found a significant warm bias. Thus, the reported global average surface temperature anomaly is also too warm.”

“More generally, we need to move beyond just assessing global warming, but examine how (and if) key atmospheric and ocean circulations, such as El Nino, La Nina, the Pacific Decadal Oscillation, etc. are changing in their intensity, structure and frequency. These are the climate features that determine if a region has drought, floods, and so forth, not a global average surface temperature anomaly,” Pielke added.

Meteorologist Dr. Ryan Maue of Florida State University ridiculed the same “hottest year” rankings in 2010 and NASA’s Hansen’s admission that it “was not particularly important” which year was declared the “hottest.” “Well, then stop issuing press releases which tout the rankings, which are subject to change ex post facto,” Maue demanded in a January 14, 2011 commentary at
