What NOAA NCEI isn't telling you in their 2014 State of the Climate Report released today
Yesterday I made mention of the fact that there would be a report today from NOAA’s National Climatic Data Center, now NCEI. Today, they have released their 2014 report, and…
NOAA/NCDC's new 'pause-buster' paper: a laughable attempt to create warming by adjusting past data
Did SNL’s Tommy Flanagan Oversee the New Surface Temperature Data? By Bob Tisdale and Anthony Watts, commentary from Dr. Judith Curry follows There is a new paper published the journal Science…
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.…
On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison
Guest Post by Bob Tisdale With the publication of the IPCC 5th Synthesis Report, I thought there might be some interest in a presentation of how well (actually poorly) climate…

Cold summer: US daily record minimums outnumbering record maximums 3 to 1 in the last 30 days
Plus, there have been new snowfall records, almost unheard of in summer. See the table:
July 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update
This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through July 2014 and HADCRUT4 and NCDC through June 2014—and of…
Should you trust NOAA claims about May and June records?
Guest essay by Joseph D’Aleo, CCM Last month was the hottest June since record keeping began in 1880, the US National Oceanic and Atmospheric Administration (NOAA) said Monday. It marked…
NOAA's own trend calculator helps confirm 'the pause' and lack of ocean warming in the 21st century
People send me stuff. Yesterday I got a note suggesting I have a look at what NOAA/NCDC’s “climate at a glance” was showing for trends in the 21st century so…
June 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update
Sorry this update is late. I got sidetracked with the post about Risbey et al. (2014), and the post about the new climate model, now with knobs. This post provides…
Practicing the Dark Art of Temperature Trend Adjustment
Did Federal Climate Scientists Fudge Temperature Data to Make It Warmer? Ronald Bailey of Reason Magazine writes: The NCDC also notes that all the changes to the record have gone…
NCDC: 'our algorithm is working as designed'
In a statement to Polifact today, NCDC made the following statement: “… our algorithm is working as designed” One wonders though, about these sorts of things that have been found…
May 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update
This post updates the data for the three primary suppliers of global land+ocean surface temperature data—GISS through May 2014 and HADCRUT4 and NCDC through April 2014—and of the two suppliers…
April 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update
Initial Notes: This is the first monthly update to include lower troposphere temperature (TLT) anomaly data. To make this post as timely as possible, only GISS LOTI and the two…
On the Differences and Similarities between Global Surface Temperature and Lower Troposphere Temperature Anomaly Datasets
UPDATE: See the correction at the end of the post, which pertained to the discussion of the trend maps in Figures 13 and 14. I’ve crossed out the paragraph between…
March 2014 Global Surface (Land+Ocean) Temperature Anomaly Update
INITIAL QUESTION Once upon a time, the NCDC published its monthly global land+ocean surface temperature anomaly data around the 15th of the month. They have recently relaxed the dates of…
GISS LOTI & NCDC Global Temperature Data Drop in February 2014
This post will serve as February 2014 Global Surface (Land+Ocean) Temperature Anomaly Update First GISS: Global surface temperatures, as represented by the GISS Land-Ocean Temperature Index (LOTI) data, dropped about…
NOAA's odd way of presenting February temperatures
Harold Ambler writes: NOAA’s map of February temperatures across the United States got New England all wrong. It wasn’t “near normal,” at all, as the people of the region can…
NOAA: US Cold records outnumber warm records 66 to 1 in the last 7 days
And nearly 3 to 1 in the last 30 days, and over 2 to 1 in 2014 From NOAA/NCDC: U.S. Records Summary The summaries below list the number of records…
January 2014 Global Surface (Land+Ocean) Temperature Anomaly Update
Initial Notes: This post contains graphs of running trends in global surface temperature anomalies for periods of 13+ and 16+ years using GISS global (land+ocean) surface temperature data. They indicate…
Why Aren’t Global Surface Temperature Data Produced in Absolute Form?
The title question often appears during discussions of global surface temperatures. That is, GISS, Hadley Centre and NCDC only present their global land+ocean surface temperatures products as anomalies. The questions…
