Urban Heat Island Studies – Do Pristine Weather Stations Even Exist?
Australia’s low population density plus its many weather stations allow many “pristine” station candidates to be examined for studies of Urban Heat Island (UHI) effects.
Urbanization Effects on GHCN Temperature Trends, Part II: Evidence that Homogenization Spuriously Warms Trends
Thus, it appears that NOAA’s homogenization procedure is spuriously warming station temperature trends (on average) when it should be cooling them. I don’t know how to conclude any different.
Canadian Summer Urban Heat Island Effects: Some Results in Alberta
Landsat-based estimates of increased urbanization suggest that this has caused a spurious warming component of reported temperature trends, at least for locations experiencing increased urbanization.
De-Urbanization of Surface Temperatures with the Landsat-Based “Built-Up” Dataset
But given the fact that all CMIP6 climate models produce U.S. summer temperature trends greater than the NOAA observations means the discrepancy between climate models and observations is even larger than currently…
Urban Heat Island Effects on U.S. Temperature Trends, 1973-2020: USHCN vs. Hourly Weather Stations
I argue that, based upon the importance of quality temperature trend calculations to national energy policy, a new dataset not dependent upon the USHCN Tmax/Tmin observations is required.
The Climate Sciences Use Of The Urban Heat Island Effect Is Pathetic And Misleading
By Geoffrey H Sherrington, Spinal Tap’s Nigel Tufnel demonstrates his hifi speakers are louder because the numbers all go to 11. https://www.youtube.com/watch?v=KOO5S4vxi0o Scientific control knobs for climate change have to…
Urban Heat Island Influence Inadequately Considered in Climate Research
Guest Opinion: Dr. Tim Ball The Intergovernmental Panel on Climate Change (IPCC) deliberately limited climate science to focus on CO2 and temperature. The United Nations Framework Convention on Climate Change…

New paper finds West Antarctic glacier likely melting from geothermal heat below
Via the Hockey Schtick – A paper published today in Earth and Planetary Science Letters finds evidence that one of the largest glaciers in West Antarctica, the Thwaites Glacier, is…
Why Automatic Temperature Adjustments Don't Work
The automatic adjustment procedure is almost guaranteed to produce spurious, artificial warming, and here’s why. Guest essay by Bob Dedekind Auckland, NZ, June 2014 In a recent comment on Lucia’s…
Important study on temperature adjustments: 'homogenization…can lead to a significant overestimate of rising trends of surface air temperature.'
From the “we told you so” department comes this paper out of China that quantifies many of the very problems with the US and global surface temperature record we have…
Unwarranted Temperature Adjustments and Al Gore's Unwarranted Call for Intellectual Tyranny
Guest essay by Jim Steele, Director emeritus Sierra Nevada Field Campus, San Francisco State University For researchers like myself examining the effect of local microclimates on the ecology of local…
Heating up in Huntsville – the discovery of FHI?
WUWT reader BarryW found this on the Huntsville Office of the State Climatologist, operated by our friend, Dr. John Christy and left it in Tips and Notes. First Christy’s article,…
Warming in the USHCN is mainly an artifact of adjustments
Dr. Roy Spencer proves what we have been saying for years, the USHCN (U.S. Historical Climatology Network) is a mess compounded by a bigger mess of adjustments. ============================================================== USHCN Surface…
Another GISS miss: warming in the Arctic – the adjustments are key
GHCN Temperature Adjustments Affect 40% Of The Arctic By Paul Homewood Before After There has been much discussion recently about temperature adjustments made by GHCN in Iceland and Greenland, which…

Frigid Folly: UHI, siting issues, and adjustments in Antarctic GHCN data
A couple of days ago I sent this email to Jeff Id of the Air vent, as he quite familiar with Antarctic surface temperature analysis, having outed the many problems…
NASA JPL on Heatwaves: "it's the asphalt, not the atmosphere"
UPDATE: Former California State climatologist Jim Goodridge presents some data that suggests that ocean temperature may be an equal or greater driving force behind Los Angeles Temperature increases, see graph…
How not to measure temperature, part 50. How to make a rural station "urban"
One of the things that happens when your work becomes well known is that people send you things to look at. Such is the case for today’s subject. Here we…
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 …
TOO HOT TO HANDLE: NIWA’s misleading temperature records
“Claimed record after claimed record, there’s evidence that NIWA’s cherrypicked data is being used (and coloured in dark red for the most extreme bits) to bolster the narrative that extreme…
