NOAA massively tampers with US temperature data, to turn a 90 year cooling trend into a warming trend. Their main excuse for doing this is Time of Observation Bias (TOBS.) NOAA says that station operators in the past used to reset … Continue reading →

The USHCN Time Of Observation BIAS (TOBS) adjustment is based on the idea that thermometers reset in the afternoon tend to double count hot days and thus produce a warm bias. For example, Warrenton, MO reset their thermometer at 5PM … Continue reading →

There is no meaningful difference in Missouri temperature trends between morning/night and afternoon stations. TOBS adjustments do nothing but corrupt the data set.

NOAA makes a large adjustment to the US temperature record based on Time Of Observation Bias. The idea is that most station operators were morons in the 1930’s, and reset their min/max thermometers in the afternoon – causing double counting … Continue reading →

Texas had their longest heatwave at Encinal in 1921, with 157 consecutive days above 90F from May 8 to October 11, 1921. The NOAA USHCN thermometer data for Texas shows 1921 as the hottest year, with Texas cooling since 1895. … Continue reading →

Micheal Mann and Snopes both did hit pieces on me this week. I must be making them nervous. Here is the Snopes article. Since 2014, climate-change deniers have squeezed millions of views, Facebook shares, and Twitter retweets by retelling a story alleging the … Continue reading →

I put together a new python script for analyzing US temperature data. The code is much smaller than what I have previously released, but it is just as powerful for the most commonly used statistics.  It also includes analysis of … Continue reading →
