Bombshell study: Temperature Adjustments Account For ‘Nearly All Of The Warming’ In Government Climate Data

Guest essay by Michael Bastasch A new study found adjustments made to global surface temperature readings by scientists in recent years “are totally inconsistent with published and credible U.S. and other temperature data.” “Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever –…

Can Temperature Adjustments Right a Wrong?

Guest Post by John Goetz Adjustments to temperature data continue to receive attention in the mainstream media and science blogs. Zeke Hausfather wrote an instructive post on the Climate Etc. blog last month explaining the rationale behind the Time of Observation (TOBS) adjustment. Mr. Hausfather pointed to the U.S. Climate Reference Network (CRN) as a…

USHCN Monthly Temperature Adjustments

Guest Essay By Walter Dnes There have been a number of posts on USHCN temperature adjustments, including 1, 2, 3, 4, 5 and 6. They have focused primarily on annual adjustments. Whilst looking into the USHCN adjustments, I noticed that each of the 12 months is adjusted differently. Here is a plot of average USHCN temperature adjustments, for each month…

Why Automatic Temperature Adjustments Don't Work

The automatic adjustment procedure is almost guaranteed to produce spurious, artificial warming, and here’s why. Guest essay by Bob Dedekind Auckland, NZ, June 2014 In a recent comment on Lucia’s blog The Blackboard, Zeke Hausfather had this to say about the NCDC temperature adjustments:

Important study on temperature adjustments: 'homogenization…can lead to a significant overestimate of rising trends of surface air temperature.'

From the “we told you so” department comes this paper out of China that quantifies many of the very problems with the US and global surface temperature record we have been discussing for years: the adjustments add more warming than the global warming signal  itself A paper just published in Theoretical and Applied Climatology finds…

Unwarranted Temperature Adjustments and Al Gore's Unwarranted Call for Intellectual Tyranny

Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University For researchers like myself examining the effect of local microclimates on the ecology of local wildlife, the change in the global average is an absolutely useless measure. Although it is wise to think globally, wildlife only responds to local climate…

Historical Sea Surface Temperature Adjustments/Corrections aka "The Bucket Model"…

Image Credit: Bob Tisdale – bobtisdale.wordpress.com By WUWT Regular Just The Facts The recent Adjustments/Corrections to the HadCRUT4 and CRUTEM4 Temperature Data Sets by the Met Office Hadley Centre and Climatic Research Unit got me thinking about the cumulative impact of Adjustments/Corrections on our temperature records. Bob Tisdale then triggered the first vein of this…

Do the Adjustments to the Global Land+Ocean Surface Temperature Data Always Decrease the Reported Global Warming Rate?

Guest Post by Bob Tisdale If you’ve read the first two posts in this series you might already believe you know the answer to the title question.  Those two posts were: Do the Adjustments to Sea Surface Temperature Data Lower the Global Warming Rate? (WattsUpWithThat cross post is here.) UPDATED: Do the Adjustments to Land Surface…

UPDATED: Do the Adjustments to Land Surface Temperature Data Increase the Reported Global Warming Rate?

Guest Post by Bob Tisdale This is an update of the post published a week ago here (WattsUpWithThat cross post is here). That earlier post included “raw” unadjusted data based on an outdated version of the NOAA GHCN dataset. This updated post includes annual land surface air temperature data through 2015 and uses the current…
