‘Hidden’ NOAA temperature data reveals that 6 of the last 9 months were below normal in the USA – and NOAA can’t even get June right

A review of state-of-the-art climate data tells a different story than what NOAA tells the public. While media outlets scream “hottest ever” for the world in June and July (it’s…

How to make use of the world’s most accurate surface temperature data

Steve, in Seattle writes: I began this project out of both frustration and a specific curiosity. I have, over the years, studied many excellent articles at WUWT. The articles that…

Death Valley’s “hottest month ever” was likely a product of nearby solar panels and RV’s

The environment around the weather station used to measure the official temperature changed dramatically in the past few years. There’s this headline circulation in the news, thanks to the Associated…

Alarmists throw in the towel on poor quality surface temperature data – pitch for a new global climate reference network

From the Journal of International Climatology and the “if you can’t beat ’em, join ’em” department. To me, this feels like vindication. For years, I’ve been pointing out just how…

@NOAA data demonstrates that 2016 was not the 'hottest year ever' in the USA

Today, there’s all sorts of caterwauling over the NYT headline by Justin Gillis that made it above the fold in all caps, no less:  FOR THIRD YEAR, THE EARTH IN…

The journalistic self-immolation of Newsweek's Zoë Schlanger

Every once in a while a new reporter arrives onto the climate scene that immediately thinks they know everything there is to know about climate, and therefore doesn’t need to…

Despite attempts to erase it globally, "the pause" still exists in pristine US surface temperature data

As readers know, the recent paper Karl et al. 2015, written by the head of the National Climatic Data Center now NCEI, went to great lengths to try to erase…

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 ‘denying’ Hockey Sticks, USHCN data, and all that – part 2

In part one of this essay which you can see here, I got quite a lot of feedback on both sides of the climate debate. Some people thought that I…

NOAA shows 'the pause' in the U.S. surface temperature record over nearly a decade

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…

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…

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…

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…

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’…
