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 →

Dennis Rancourt is a PhD physicist, civil libertarian, and climate skeptic.  He has interviewed me about climate for the Ontario Civil Liberties Association. Dr. Rancourt has an excellent paper out explaining why masks don’t work, and how governments are operating … 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 →
