Climategate Darwin

Hot on the heels of the East Anglia Climatic Research Unit’s Climategate, here is yet more global warming dishonesty exposed.


Excerpted from Watts Up With That:

Then I went to look at what happens when the GHCN removes the “in-homogeneities” to “adjust” the data. Of the five raw datasets, the GHCN discards two, likely because they are short and duplicate existing longer records. The three remaining records are first “homogenized” and then averaged to give the “GHCN Adjusted” temperature record for Darwin.

To my great surprise, here’s what I found. To explain the full effect, I am showing this with both datasets starting at the same point (rather than ending at the same point as they are often shown).

Figure 7. GHCN homogeneity adjustments to Darwin Airport combined record

YIKES! Before getting homogenized, temperatures in Darwin were falling at 0.7 Celcius per century … but after the homogenization, they were warming at 1.2 Celcius per century. And the adjustment that they made was over two degrees per century … when those guys “adjust”, they don’t mess around. And the adjustment is an odd shape, with the adjustment first going stepwise, then climbing roughly to stop at 2.4C.

Intrigued by the curious shape of the average of the homogenized Darwin records, I then went to see how they had homogenized each of the individual station records. What made up that strange average shown in Fig. 7? I started at zero with the earliest record. Here is Station Zero at Darwin, showing the raw and the homogenized versions.

Figure 8 Darwin Zero Homogeneity Adjustments. Black line shows amount and timing of adjustments.

Yikes again, double yikes! What on earth justifies that adjustment? How can they do that? We have five different records covering Darwin from 1941 on. They all agree almost exactly. Why adjust them at all? They’ve just added a huge artificial totally imaginary trend to the last half of the raw data! Now it looks like the IPCC diagram in Figure 1, all right … but a six degree per century trend? And in the shape of a regular stepped pyramid climbing to heaven? What’s up with that?

Those, dear friends, are the clumsy fingerprints of someone messing with the data Egyptian style … they are indisputable evidence that the “homogenized” data has been changed to fit someone’s preconceptions about whether the earth is warming.

One thing is clear from this. People who say that “Climategate was only about scientists behaving badly, but the data is OK” are wrong. At least one part of the data is bad, too. The Smoking Gun for that statement is at Darwin Zero.

So once again, I’m left with an unsolved mystery. How and why did the GHCN “adjust” Darwin’s historical temperature to show radical warming? Why did they adjust it stepwise? Do Phil Jones and the CRU folks use the “adjusted” or the raw GHCN dataset? My guess is the adjusted one since it shows warming, but of course we still don’t know … because despite all of this, the CRU still hasn’t released the list of data that they actually use, just the station list.

Another odd fact, the GHCN adjusted Station 1 to match Darwin Zero’s strange adjustment, but they left Station 2 (which covers much of the same period, and as per Fig. 5 is in excellent agreement with Station Zero and Station 1) totally untouched. They only homogenized two of the three. Then they averaged them.

That way, you get an average that looks kinda real, I guess, it “hides the decline”.

Oh, and for what it’s worth, care to know the way that GISS deals with this problem? Well, they only use the Darwin data after 1963, a fine way of neatly avoiding the question … and also a fine way to throw away all of the inconveniently colder data prior to 1941. It’s likely a better choice than the GHCN monstrosity, but it’s a hard one to justify.

What this does show is that there is at least one temperature station where the trend has been artificially increased to give a false warming where the raw data shows cooling. In addition, the average raw data for Northern Australia is quite different from the adjusted, so there must be a number of … mmm … let me say “interesting” adjustments in Northern Australia other than just Darwin.

And with the Latin saying “Falsus in unum, falsus in omis” (false in one, false in all) as our guide, until all of the station “adjustments” are examined, adjustments of CRU, GHCN, and GISS alike, we can’t trust anyone using homogenized numbers.

    “Climategate” started out when there appeared on the Internet a collection of e-mails of a group of climatologists who work in the University of East Anglia in England. These documents reveal that some climatologists of international preeminence have manipulated the data of their investigations and have strongly tried to discredit climatologists who are not convinced that the increasing quantities of carbon dioxide in our atmosphere are the cause of global warming.

    It is true that a majority of the scientists who study climatic tendencies in our atmosphere have arrived at the conclusion that the world’s climate is changing, and they have convinced a group of politicians, some of whom are politically powerful, of the truth of their conclusions.

    A minority, however, is skeptical. Some believe that recent data that suggest that the average temperature of the atmosphere is going up can be explained by natural variations in solar radiation and that global warming is a temporary phenomenon. Others believe that the historical evidence indicating that the temperature of the atmosphere is going up at a dangerous rate is simply not reliable.

    Such lacks of agreement are common in the sciences. They are reduced and eventually eliminated with the accumulation of new evidence and of more refined theories or even by completely new ones. Such debates can persist for a period of decades. Academics often throw invective at one another in these debates. But typically this does not mean much.

    But the case of climate change is different. If the evidence indicates that global warming is progressive, is caused principally by our industrial processes, and will probably cause disastrous changes in our atmosphere before the end of the twenty-first century, then we do not have the time to verify precisely if this evidence is reliable. Such a process would be a question of many years of new investigations. And if the alarmist climatologists are right, such a delay would be tragic for all humanity.

    The difficulty is that economic and climatologic systems are very complicated. They are not like celestial mechanics, which involves only the interaction of gravity and centrifugal force, and efforts to construct computerized models to describe these complicated systems simply cannot include all the factors that are influential in the evolution of these complicated systems.

    All this does not necessarily indicate that the alarmist climatologists are not right. But it really means that if global warming is occurring, we cannot know exactly what will be the average temperature of our atmosphere in the year 2100 and what will be the average sea level of the world’s ocean in that year.

    It also means that we cannot be confident that efforts by the industrialized countries to reduce the amount of carbon dioxide in our atmosphere will have a significant influence on the evolution of the world’s climate.

    Alas, the reduction of carbon dioxide in our atmosphere would be very costly and would greatly change the lives of all the inhabitants of our planet–with the possibility (perhaps even the probability!) that all these efforts will be completely useless.
