Australian Temperatures in cities adjusted up by 70%!?

Ken Stewart has been hard at work again, this time analyzing the Australian urban records. While he expected that the cities and towns would show a larger rise than records in the country due to the Urban Heat Island Effect, what he found was that the raw records showed only a 0.4 degree rise, less than the rural records which went from a raw 0.6 to an adjusted 0.85 (a rise of 40%). What shocked him about the urban records were the adjustments… making the trend a full 70% warmer.

The largest adjustments to the raw records are cooling ones in the middle of last century. So 50 years after the measurements were recorded, officials realized they were artificially too high? Hopefully someone who knows can explain why so many thermometers were overestimating temperatures in the first half of the 1900′s.

50 years later?

The raw Australian urban temperature records are in blue. The adjusted records in red. Note that temperatures in the middle of last century appear to be adjusted downwards. These are the annual average recordings for all 34 sites.

The Great Dying of Thermometers

It’s like watching the lights go out over the West. Sinan Unur has mapped the surface stations into a beautiful animation. His is 4 minutes long and spans from 1701-2010. I’ve taken some of his snapshots and strung them into a 10 second animation.

You can see as development spreads across the world that more and more places are reporting temperatures. It’s obvious how well documented temperatures were (once) in the US. The decay of the system in the last 20 years is stark.

For details on just how sinister the vanishing of data records is, see my previous post on Anthony Watts and Joe D’Aleo’s extraordinary summary of Policy Driven Deception.

The Great Dying of Thermometers

LATE POST NOTE

Sinan points out that people might not realize that many thermometers haven’t actually disappeared — they are often still collecting data — it’s just that their records are not being included in the “global” compilations. Though, as Watts and D’Aleo point out, sometimes these forgotten thermometers are still used to calculate the baseline averages.

I’m sure one day the chronological spread (and decay) of thermometers will be a useful marker for some socio/economic/historic marker (though it’s [...]

Is there any unmassaged data out there?

This is yet another example of things that don’t add up in the world of GISS temperatures in Australia. Previously, we’ve discussed Gladstone and Darwin.

Ken Stewart has been doing some homework, and you can see all the graphs on his blog. Essentially, the Bureau of Met in Australia provides data for Mt. Isa that shows a warming trend of about 0.5 degrees of warming over a century. GISS takes this, adjusts it carefully to “homogenize urban data with rural data”, and gets an answer of 1.1 degrees. (Ironically among other things, “homogenisation” is supposed to compensate for the Urban Heat Island Effect, which would artificially inflate the trend in urban centers.)

To give you an idea of scale, the nearest station is at Cloncurry, 106km east (where a flat trend of 0.05 or so appears in the graph). But, there are other trends that are warmer in other stations. Averaging the five nearest rural stations gives about 0.6 degrees; averaging the nearest ten stations gives between 0.6 and 0.88 degrees.

Horrifying examples of deliberate tampering

Just when you thought it couldn’t get worse for the cult of the carbon scare.

Now we need to ask if the world has even warmed? I’ve always said, “global warming is real”, but the recent exposés of shocking corruption in science have made me start to wonder whether even that is true.

Today a study by Joe D’Aleo and Anthony Watts, was announced by the Science and Public Policy Institute (SPPI).

From their media release:

An extensive survey of the literature and data regarding ground and sea surface temperature records uncovers deception through data manipulation, reports the Science and Public Policy Institute (SPPI).

Authors veteran meteorologists Joe d’Aleo and Anthony Watts analyzed temperature records from all around the world for a major SPPI paper, Surface Temperature Records – Policy-driven Deception? The startling conclusion that we cannot tell whether there was any significant “global warming” at all in the 20th century is based on numerous astonishing examples of manipulation and exaggeration of the true level and rate of “global warming”.

That is to say, leading meteorological institutions in the USA and around the world have so systematically tampered with instrumental temperature data that it [...]

Smoking guns across Australia: Where’s the warming? Looking at 16 other locations

If there was enough money, fame and power on the table (think seismic proportions, money that moves the economic landscape), would it be possible to take a small unproven scientific theory as an excuse and, with the best PR teams in the world, promote it, support it, and make it appear unquestionable?

If it were cloaked in the most “innocent” of motives, and shrouded in terminology that veils the truth, would it not run unchecked for years, unless some big vested interest opposed it? And if there was no particular big vested interest to oppose it, isn’t it possible that if the only harm it causes is to the giant disorganized mass known as humankind, there would be no committee of humankind to check its momentum.

On Watts Up tonight, we get some insight into just one specific example of how corrupt science can be. It’s yet another day in the history of the climate-scam where people may say years from now… remember that night we got the news about Darwin? Thanks to Willis Eschenbach’s dedicated analysis.

The blue line is the raw unadjusted data from Darwin. There are five stations there and their records [...]
