Which mercury reading in Mercury is the right one?

How can two stations less than 1/2 mile apart be so different? How can one set a new record and best it by two degrees while the other doesn’t? I was intrigued by this Record Event Report out of Las … Continue reading

It seems NOAA has ‘de-modernized’ the official Death Valley station to use older equipment to make a record more likely

About those ‘record’ Death Valley temperatures everybody is waiting for… UPDATE: 128°F today at Death Valley COOP station. See Record Event Report below. It seems the media and the alarmists are cheering on the possibility of an all-time temperature record … Continue reading

Boulder Escapes Global Warming

Guest post by Sam I. Outcalt Abstract: The historic record of the mean annual air temperature record at Boulder does not display the major “global” climate transitions detectable in the total annual precipitation record. Hurst ReScaling is demonstrated to be … Continue reading

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

A new paper showing how UHI and energy consumption are linked to long-term temperature change in China

Dr. Roger Pielke Sr. highlighted this major new paper in JGR yesterday, I consider it important as it relates to the works I’m doing on station siting. The key points of the paper are supportive of what I’ve  been saying … 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

How not to measure temperature, part 93: the hottest weather station in the UK cited by the BBC has some interesting exposure

Over at Tallbloke’s Talkshop, moderator Tim Channon wondered about this regularly hot station reported in the news: An often appearing name in the BBC news as the hottest place in the country is Gravesend but the true location of the … Continue reading

Never before published paper on UHI and siting – Goodridge 1987

Plus answers to yesterday’s Fun puzzle: Name these official stations. Given that California Governor Jerry Brown has recently setup a website at the governor’s office basically telling skeptics to “shut up” I thought this would be a good time to … Continue reading

Fun puzzle: Name these official stations

Here’s a fun little puzzle for you, two older station siting photographs from former California State Climatologist, Jim Goodridge, circa the 1980′s. I had Jim find these because I was recently interviewed for a national network newscast, and when I … Continue reading

An ‘inconvenient result’ – July 2012 not a record breaker according to data from the new NOAA/NCDC U.S. Climate Reference Network

I decided to do myself something that so far NOAA has refused to do: give a CONUS average temperature for the United States from the new ‘state of the art’ United States Climate Reference Network (USCRN). After spending millions of … Continue reading
