UAH, RSS, NOAA, UW: Which Satellite Dataset Should We Believe?

Reposted from Dr. Roy Spencer’s Blog April 23rd, 2019 by Roy W. Spencer, Ph. D. This post has two related parts. The first has to do with the recently published study of AIRS satellite-based surface skin temperature trends. The second is our response to a rather nasty Twitter comment maligning our UAH global temperature dataset…

Australia Surface Temperatures Compared to UAH Satellite Data Over the Last 40 Years

Reposted from Dr. Roy Spencer’s Blog April 3rd, 2019 by Roy W. Spencer, Ph. D. Summary: The monthly anomalies in Australia-average surface versus satellite deep-layer lower-tropospheric temperatures correlate at 0.70 (with a 0.57 deg. C standard deviation of their difference), increasing to 0.80 correlation (with a 0.48 deg. C standard deviation of their difference) after…

Evidence that humans are responsible for global warming hits ‘gold standard’ certainty level

An article from Apple news notes: OSLO – Evidence for man-made global warming has reached a “gold standard” level of certainty, adding pressure for cuts in greenhouse gases to limit rising temperatures, scientists said on Monday. “Humanity cannot afford to ignore such clear signals,” the U.S.-led team wrote in the journal Nature Climate Change of…

January 2016 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

Guest Post by Bob Tisdale UPDATE: All graphs with UAH lower troposphere temperature data have been updated from beta version 6.4 to 6.5. Thanks, Nick Stokes. This means Figure 4 and Figures 6 through 9 have been revised. # # # The GISS Land-Ocean Temperature Index jumped upwards more than 0.2 deg C from September…

May 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

Guest Post by Bob Tisdale This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through May 2015 and HADCRUT4 and NCEI (formerly NCDC) through April 2015—and of the two suppliers of satellite-based lower troposphere temperature data (RSS and UAH) through May 2015. INITIAL NOTES: I’m…
