NASA Faked Climate Data Says Retired Top UK Govt. Scientist

Retired Principal Scientific Officer (PSO) for the British Government exposes how NASA rigged the Global Historical Climate Network (GHCN) to make recent temperatures seem warmer.

The fraud was intended to give scientific credence to tax-raising UK and US climate policies.

The unnamed source, now retired from the UK Scientific Civil Service and speaking exclusively to Principia Scientific International (PSI), was so disturbed by the “tampering” of government temperature records, he performed his own verification tests and exposed a shocking anomaly that turns the global warming narrative on its head.

The highly qualified whistleblower reveals that he downloaded the raw station data from NASA/GISS gridded land anomaly products and compared them with the anomalies.

He told PSI:

Having processed NASA GISS 250km T2m and 1200Km T2m global land anomaly data products I also processed Global Historical Climate Network (GHCN) daily mean temperature records from the 1,045 stations that have been continuously operative since 1900.

 Since these 1,045 stations form the backbone of the historical world meteorological network, and therefore NASA GISS products, we may expect results to be largely similar, though with the inflated variance within the GHCN-D data series (GISS anomalies are highly processed products). Not addressed in this study is the urban heat island effect which is known to contaminate the land-based record.

Prior to 1970 there is an inexplicable divergence in that NASA GISS products show historic global land temperatures to have been cooler than those recorded by the 1,045 GHCN-D stations; this difference is most pronounced around 1930 when extreme heatwaves were experienced across the continental US and in other parts of the world (a fact recorded in newspapers of the day).

The extremes of the 1930s/40s down to the cooler 1960s/70s prompted scientific discussion of a pending ice age.

The retired top government scientist laments that he is old enough to remember the wild media scaremongering of the 11970sabout global cooling.

He spoke of how the very same scientists and government bodies that were warning of impending ice in the seventies are the very same tax zealous advocates hyping global warming today.

The anonymous source affirms that inside the government there is an agenda to promote wild supposition and media scaremongering.

The only difference this time is the narrative is all about “unprecedented” global warming, not the threat of an imminent ice age.

However, to expose the lies, he reveals that global land temperature anomalies estimated as high as 1.23°C today were actually occurring routinely as far back as 1934.

These temperatures only surpassed again in 2015. Persuaded by the raw data he examined, the former top UK government expert is adamant there is nothing abnormal about recent global temperatures.

He told me:

“I thus decided to run a few statistical procedures to highlight the improbability of these differences arising by chance. (slide #1)

The period 1914 – 2018 was divided into seven 15-year periods and a difference series derived from NASA GISS 250km T2m and the GHCN-D Tavg 1,045 station series.

Whilst a fair degree of variation between the two series is to be expected the differenced series should theoretically manifest itself as a normally or near-normally distributed variable with an overall mean value of zero or near-zero.

Slide #2 is a snapshot of a repeated one sample t-test for each of the seven-year periods in which the mean value of the differenced series is tested against the null hypothesis.

Only periods 1974- 1988 and 1989-2003 can be considered free of systematic bias with p-values of p=0.593 and p=0.070 respectively. Bias for the earliest three periods is particularly pronounced, where we may note inexplicable cooling of the NASA gridded product by as much as 0.612°C (1929-1943, p<0.001).

We may also note an inexplicably warmer present than expected, with a bias of 0.317°C creeping into NASA gridded product for the period 2004-2018 (p=0.029).

The pattern of bias over the seven data periods prompted the retired top UK scientist to produce slide #3, this being a time series plot of the differenced series for 1900 – 2018.

The whistleblower adds:

There is no way that simple estimation error is going to produce a slope like this: we should see data points randomly scattered about the zero value of the y-axis.

In this chart, the dark red line is an OLSR whose slope estimate was calculated at +0.1°C per decade (p<0.001), and the black line is an Epanechnikov (50%) smoothing function to guide the eye.

Fitted values for the OLSR trendline reveal that between 1900 and 2018 NASA has somehow systematically and inexplicably added +1.16°C to their 250 T2m global land anomaly gridded product when compared to GHCN-D data based on a sample of 1,045 stations.

I cannot as yet explain this and encourage statistically- minded climate enthusiasts to pull down data and confirm this extraordinary finding for themselves.

Having studied our whistleblower’s calculations it is very evident to us that they have a striking similarity to the findings of noted American climate skeptic Tony Heller.

Data fraud and ‘secret science’ tampering of the actual historical temperature record was recently a feature in the epic court victory of Canadian skeptic, Dr. Tim Ball over Dr. Michael E Mann.

Principia Scientific International is currently liaising with legal experts with a view to lobbying Congress to initiate and full RICO investigation into this mounting evidence of government climate fraud.
