I was invited to speak at the Liberal Democrats Conference in Sydney last Sunday. I began by explaining that while the delegates may have though homogenization was a term used exclusively for milk, that homogenization is also a technical term used in climate science, but with an altogether different meaning. It allows scientists to remodel historical temperature data so it’s closer to the heart’s desire.
These few words – closer to the heart’s desire – have been borrowed from that famous poem the Rubaiyat of Omar Khayyam. The stanza reads:
Ah, Love! could thou and I with Fate conspire
To grasp this sorry Scheme of Things entire!
Would not we shatter it to bits-and then
Re-mould it nearer to the Heart’s Desire!
Omar used the word “remould”, climate scientists say they are improving the data.
The end result is the same: something has been changed.
The scientific revolution rejected unnatural causes to explain natural phenomena, rejected appeals to authority, and rejected revelation, in favor of empirical evidence. Today, the biggest threat to science is from the sophisticated remodeling of data, known in climate science as homogenization.
An analogy can be made between the remodeling of scientific data, which is now common in a variety of disciplines from conservation biology to climate science, and “fitting up” people the police know to be guilty, but for whom they can’t muster enough forensic evidence for a conviction. This is also a form of “noble cause corruption”.
Why is it a form of corruption? Because we expect the criminal justice system to be fair, to be based on legitimate evidence. Science should also be about facts, and evidence.
Let’s consider a real world example of homogenization, specifically the maximum temperature record for Darwin.
There are very few continuous, surface temperature recording from northern Australia that extend beyond 60 years. The Australian Bureau of Meteorology, Hadley Centre (UK Met Office), Goddard Institute for Space Studies (NASA GISS), and other institutions concerned with the calculation of global temperature trends, join temperatures recorded at the Darwin post office from 1882 until January 1942 with temperatures from the Darwin airport recorded from February 1941 to the present, and then make adjustments. There is no temperature record at the post office after 1942 because the Darwin post office was bombed in Japanese air raids.
Temperatures were recorded at the Darwin post office from 1882, but are only shown in Figure 1 from 1895, which is the first full year of recordings in a Stevenson screen.
