Grandma Learns About Data Adjustment: A little story about how data adjustment might work in everyday life.
Note: On Thursday of this week, NOAA/NCDC will attempt to rewrite the surface temperature record yet again, making even more “adjustments” to the data to achieve a desired effect. This…
New Zealand's NIWA sued over climate data adjustments
NIWA is being sued by the NZ Climate Coalition, mainly due to the differences in data in this graph: Niwa sued over data accuracy The country’s state-owned weather and atmospheric…
Data adjustments in the UK Science Museum "Prove It!" poll on climate
Seems everywhere you look these days, data adjustments are being made. Shortly after WUWT first made the UK Science Museum Prove It! poll on climate change known here, Ric Werme…
More on the NIWA New Zealand data adjustment story
NIWA issued a response statement regarding the charges leveled by The NZ Climate Science Coalition here: http://www.niwa.co.nz/our-science/climate/news/all/niwa-confirms-temperature-rise They say: Warming over New Zealand through the past century is unequivocal. NIWA’s…
Bombshell study: Temperature Adjustments Account For ‘Nearly All Of The Warming’ In Government Climate Data
Guest essay by Michael Bastasch A new study found adjustments made to global surface temperature readings by scientists in recent years “are totally inconsistent with published and credible U.S. and…
HadCRUT Adjustments and the 1.5°C Tipping Point. (Now Includes September Data Except for HadCRUT)
Guest Post by Werner Brozek, Edited by Just The Facts: A new HadCRUT4.5 data set came out last month. HadCRUT4.5 replaces HadCRUT4.4. In an earlier post, I commented on how…
Remote Sensing Systems apparently slips in a 'stealth' adjustment to warm global temperature data
People send me stuff. Today, alert reader Clay Ablitt sends this: I have been keeping a record of a lot of the different data sets that are put out by RSS and…
Do the Adjustments to the Global Land+Ocean Surface Temperature Data Always Decrease the Reported Global Warming Rate?
Guest Post by Bob Tisdale If you’ve read the first two posts in this series you might already believe you know the answer to the title question. Those two posts…
UPDATED: Do the Adjustments to Land Surface Temperature Data Increase the Reported Global Warming Rate?
Guest Post by Bob Tisdale This is an update of the post published a week ago here (WattsUpWithThat cross post is here). That earlier post included “raw” unadjusted data based…
Do the Adjustments to Land Surface Air Temperature Data Increase the Global Warming Rate?
Guest Post by Bob Tisdale Quick Answer: Over the long term, the answer is yes, and the differences between datasets are noticeable. Over shorter terms, the answer depends on the…
Do the Adjustments to Sea Surface Temperature Data Lower the Global Warming Rate?
Guest Post by Bob Tisdale Quick answer: Over the long term, the answer is yes, but for shorter terms it depends on the sea surface temperature dataset and time period.…

Yet Even More Nonsense from Grant Foster (Tamino) et al. on the Bias Adjustments in the New NOAA Pause-Buster Sea Surface Temperature Dataset
Guest Post by Bob Tisdale UPDATE: It was pointed out in a comment that the model-data comparison in the post was skewed. I was comparing modeled marine air temperature minus…

Climate Change Weekly #503: Official Temperature Data Isn’t ‘Data’ At All
In fact, we found that 89 percent of the stations—nearly 9 of every 10—fail to meet the National Weather Service’s own siting requirements …
Hidden Behind Climate Policies, Data From Nonexistent Temperature Stations
Hundreds of ‘ghost’ climate stations are no longer operational; instead they are assigned temperatures from surrounding stations.
Junk Science Alert: Met Office Set to Ditch Actual Temperature Data in Favour of Model Predictions
…using this highly politicised method would indicate that reality is rapidly departing from the Met Office station.
Parallel Temperature Data, Except for Cape Otway Lighthouse
These findings are not consistent with claims made by the Bureau that there is no public interest in releasing the parallel data because the temperatures are the same whether measured…
Why We Need an Independent Global Climate Temperature Database
Given that governments are spending billions of taxpayer dollars on climate mitigation programs, doesn’t it make sense to get the most important thing – the actual temperature – as accurate as…
The Danger Of Short Datasets
