The heat is on: the UK SurfaceStations effort

They say “imitation is the sincerest form of flattery”, so color me flattered. I’ve been remiss in writing about this effort by Roger Tattersall (aka Tallbloke) and his colleague Tim Channon, but a tip from WUWT reader David Schofield brought … Continue reading

NOAA’s ‘Janus moment’ – while claiming ‘The American public can be confident in NOAA’s long-standing surface temperature record’, they fund an experiment to investigate the effects of station siting and heat sinks/sources on temperature data

NOAA’s impersonation of the two faced god Janus just proved my point about station siting issues with their actions that speak louder than words. While there’s all this caterwauling about my PBS News hour interview, and my statements were apparently … Continue reading

Errors in Estimating Mean Temperature – Part II

Guest post by Lance Wallace Last week (Aug 30), Anthony Watts posted my analysis of the errors in estimating true mean temperatures due to the use of the (Tmin+Tmax)/2 approach widely used in thousands of temperature measuring stations worldwide: http://wattsupwiththat.com/2012/08/30/errors-in-estimating-temperatures-using-the-average-of-tmax-and-tmin-analysis-of-the-uscrn-temperature-stations/Continue reading

Errors in Estimating Temperatures Using the Average of Tmax and Tmin—Analysis of the USCRN Temperature Stations

Guest post by Lance Wallace Abstract The traditional estimate of temperature at measuring stations has been to average the highest (Tmax) and lowest (Tmin) daily measurements. This leads to error in estimating the true mean temperature. What is the magnitude … Continue reading

July was also the 329th consecutive month of positive upwards adjustment to the U.S. temperature record by NOAA/NCDC

I’ve noticed there’s a lot of frenetic tweeting and re-tweeting of this “sound bite” sized statement from this Climate Central piece by Andrew Freedman. July was the fourth-warmest such month on record globally, and the 329th consecutive month with a … Continue reading
