Background

When first investigating the global warming/climate change issue (beginning around the Copenhagen COP in 2008), my interest arose from reading various claims repeated ad nauseum without any other viewpoints expressed. Searching on the web revealed that indeed other researchers had different, sometimes nuanced and sometime outright contradictory findings.

In 2015 while signing up on WordPress to be able to comment on Climate Etc., I was surprised to find that the process left me with my own blogsite. So I began to put up posts of researches I had done, some were data analyses of my own, and others were discussions of analyses done by others. It has always been a niche project intending to provide information and a broader context related to climate science claims, for the sake of others who might be interested but lacked the time or energy to dig in the weeds for the all-important details.

Lately we have a sea change in the discourse around global warming/climate change. The Paris accord and the subsequent US withdrawal from it, along with the tumult around Trump’s presidency, Brexit, the broken electricity grid in Australia, have all shifted the focus from scientific discrepancies to policy questions.

It pleases me that in this current media setting, diverse and skeptical voices are more easily heard by those with inquiring minds who want to know. For example, Master Resource blog provides expert analyses on energy issues such as subsidies and renewables challenges. Other well-known blogs such as WUWT and Notalotofpeopleknowthat are actively addressing exaggerations and bogus claims by activists.

It also looks more likely that we will be treated to an official investigation into the EPA case for CO2 endangerment. Some studies by prominent skeptics are appearing as resources in that context.

So, there are many others rebutting unfounded claims, and less need for me to write such posts. It is also the case that this blog already contains multiple posts on almost all the issues that continue to be raised. This is the first of a series pointing out resources compiled here.

1.Temperature Trend Analysis

This category of posts (title above is link to posts) started some years ago when Dave from California commented on a thread at WUWT:  “I am an actuary not a climate scientist, but it seems to me if you want to know about temperature changes, you should study the changes not the temperatures.”  That rang my bell and suddenly things came together. JR Wakefield studied the change derivatives (slopes) of temperature changes at individual weather stations in Ontario. Lubos Motl did a similar analysis using monthly trends over station lifetimes as a basis for compiling global trends–no anomalies, no adjustments or homogenization.

I termed this technique Temperature Trend Analysis (TTA) and applied it to a set of station records in Kansas and the report was published at WUWT in 2014 with the title Do-It-Yourself Climate Analysis

Richard Mallet and I then collaborated on a study of the 25 best stations in the world (longest continuous records) also published at WUWT as Analyzing Temperature Changes Using World Class Stations. Later on I applied TTA to US stations classified as CRN #1 and then assessed the differences between adjusted and unadjusted datasets. The results were published at No Tricks Zone and then posted as Temperature Data Review Project-My Submission.

Just this week we have a thorough and professional report on the systematic corruption of the land station records by climate authorities:  On the Validity of NOAA, NASA and Hadley CRU Global Average Surface Temperature Data & The Validity of EPA’s CO2 Endangerment Finding  From the Report:

This research sought to validate the current estimates of Global Average Surface Temperature (GAST) using the best available relevant data. The conclusive findings were that the three GAST data sets are not a valid representation of reality. In fact, the magnitude of their historical data adjustments which removed their cyclical temperature patterns are totally inconsistent with published and credible U.S. and other temperature data.  Thus, despite current claims of record setting warming, it is impossible to conclude from the NOAA, NASA and Hadley CRU GAST data sets that recent years have been the warmest ever.

Additional studies included an analysis of Temperatures According to Climate Models
