Two Decades of Temperature Data from Australia – Not Fit for Purpose – Jennifer Marohasy

What is going on with Australian temperature data? It doesn’t look good, as Jennifer Marohasy explains.

Australia is a large continent in the Southern Hemisphere. The temperatures measured and recorded by the Australian Bureau of Meteorology contribute to the calculation of global averages.

These values, of course, suggest catastrophic human-caused global warming. Two decades ago the Bureau replaced most of the manually-read mercury thermometers in its weather stations with electronic devices that could be read automatically – so since at least 1997 most of the temperature data has been collected by automatic weather stations (AWS).

Before this happened there was extensive testing of the devices – parallel studies at multiple site to ensure that measurements from the new weather stations tallied with measurements from the old liquid-in-glass thermometers.

New Dawn Of Truth: London Climate Change Conference 2016

It’s finally happening. Thanks to Herculean efforts by Niklas Morner, we are presenting a two-day conference in central London on the 8-9th September. Speakers are coming from all over the world to present their work, and it is not to be missed!

Take the 8-9th September off work and join us for this historic event. The first UK climate conference in decades which will counter the scaremongering of the IPCC with a cool, rational approach to the study of climate change, presenting alternative explanations, new data, theory and commentary. Topics include solar-planetary theory, causes of ENSO, sea ice extent, sea level, ozone depletion, volcanos, regional forecasting, journal gatekeeping and many more.

The list of contributors is long, we are packing a huge number of presentations into this two day event. Speakers include Niklas Morner, myself, Ned Nikolov and Karl Zeller,  Nicola Scafetta, Per Strandberg, Jan-Erik Solheim, and thats before lunch on day one! Piers Corbyn will be there! So will  Christopher Monckton! See the full programme and the extended abstracts in this 35 Megabyte document for full details.

Stonehenge transport mystery solved?

Whether this is ‘case closed’ is uncertain but it does seem to offer another option to resolve the puzzle, as the Telegraph explains.

It is an archaeological conundrum that has baffled generations of experts. Just how did prehistoric Britons manage to transport the huge bluestones of Stonehenge some 140 miles from the Preseli Mountains in Wales to their final home on Salisbury Plain, Wiltshire?

The answer is surprisingly simple. The feat really isn’t as hard as everyone imagined.

Conversation with Paul Pukite

Can a gaseous atmosphere really radiate as a ‘black-body’?

Commenter ‘USteiner’ asks this question on suggestions 16 and explains the reason for asking.

Let’s put aside the conclusion that CO2 makes the antarctic cool the earth. In the Schmithüsen paper (http://onlinelibrary.wiley.com/doi/10.1002/2015GL066749/full) they claim to have made the calculation, and it shows that. However, what is new? This had been measured with – gosh – real data some 45 years (!) ago. See here the Nimbus data from 1971 in Fig. 12d (http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19710026041.pdf )

Further, look at Schmitthüsen’s Fig 2. You see the spike on the CO2 pimple at the South pole at a Spectral radiance of 2.5. And exactly at the same level for the US Standard atmosphere. This is at least consistent with an interpretation that CO2 radiates the same everywhere on earth, but becomes only visible, when the background black body radiation from the ground is low enough. And this requirement is fulfilled only at the very cold south pole. So, what is left as excitement?

Arctic ice data conflict, example of software tool usage

Moderator Tim Channon writes: This article is unusual for the Talkshop. I may for personal reasons be leaving the Talkshop, a consequence of recent serious troubles, why I have been quiet. I hope this proves untrue.
I want to get some items out in the world for others. From my point of view leave a legacy. I am releasing the Synth software, done rapidly so none of this is neat or complete.

This is a simple example of usage with perhaps some current interest. No answers are intended for more the whole idea is about gaining insight by you playing around with data and ideas.

Figure 1

According to published datasets the characteristics of sea ice changed around 2006/7. Dataset used here is NSIDC/NOAA D02135 monthly. ( if you try and decode the published data, read the notes, has offsets which need compensation, do not use as is)

Based on experience I think this change is in the data gathering, perhaps geometry, not actual ice change. In the past in various articles I’ve mentioned some of the dubious practices.

Temperature variation at Heathrow over the past year

This article is part of preparing the way for later revelations about instrumentation defects.

Figure 1 (upper), Figure 2 (lower) computed mean insolation for horizontal surface at this exact location and weather parameters, no cloud.

Figure 1 (upper), Experimental work[1] showing nearly daily temperature variation from expected, specifically designed to exclude diurnal but include detail variation at the fastest scale feasible. Time graticule at 10 days, data points at 12 hours. Surprisingly the July 1st hot period has vanished. Plots of other sites show a similar effect. The most frequent warm and cool periods of weather are brief and readily seen.

This computation will produce different values from the mean values computed from thermometer minimum and maximum data because data shape at other times is taken into account, min/max does not. The filter used is also windowed, leakage is negligible.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Thorshavn, Faroe Islands

In 2003, two proper scientists wrote a paper on the climate of the Faroe Islands, which lie between Iceland and Norway.

http://research.iarc.uaf.edu/NICOP/DVD/ICOP%202003%20Permafrost/Pdf/Chapter_026.pdf

They published this graph of air temperatures at the capital Torshavn.

And commented:

So we find confirmation of the 1925-40 warm period, and that the recent temperature rise is no more than a natural recovery from the colder 1950-80 interval.

Of course, temperatures may have risen since 2003, but the raw GISS data shows otherwise.

Below is their graph based on the raw GHCN V2 temperatures, as they appeared in 2011. (The warmest year was 2003 itself).

ABSTRACT
Aims. The Maunder minimum (MM) of greatly reduced solar activity took place in 1645–1715, but the exact level of sunspot activity is uncertain because it is based, to a large extent, on historical generic statements of the absence of spots on the Sun. Using a conservative approach, we aim to assess the level and length of solar cycle during the MM on the basis of direct historical records by astronomers of that time.

http://www.independent.co.uk/news/science/climate-change-sceptic-group-sets-up-inquiry-into-accuracy-of-global-temperature-records-10204961.html

It has not taken long for the left wing press to attack the investigation into the integrity of global temperature records!

The UK’s most prominent climate change denial group is launching an inquiry into the integrity of global surface temperature records.

The Global Warming Policy Foundation (GWPF), established by notable climate-change sceptic Lord Lawson, announced an international team of “eminent climatologists, physicists and statisticians” would investigate the reliability of the current data.

Professor Terence Kealey, the former vice-chancellor of the University of Buckingham, has been appointed chair of the international temperature data review project.

Professor Kealey studied medicine at Oxford University before lecturing on clinical biochemistry, which is primarily concerned with the analysis of bodily fluids, at Cambridge University. It is unclear what experience he has in the field of climate change.

The other five commissioners of the data review project: Petr Chylek, Richard McNider, Roman…

Normalised UK regional temperature

The fuss about extreme rainfall last year tripped me into looking for myself. This led to an innovative analysis of Met Office areal time series for precipitation. There was little interest shown but also little criticism. I’m bringing up Windows 8.1 64 here, same hardware, testing various codebases.
As a wonder-if… the Met Office publish areal series for air temperature, Tmean, Tmax and Tmin. Daft idea, pull one file and eyeball, looks the same data format as rainfall. Do the lazy thing, copy code to a new directory, few trivial edits and hit go. It works. The results look sane.

Tmean for East Scotland, one of 68 plots. The four PDF, Tmean, Tmax, Tmin and Precipitation are linked later. Zoom to any scale works on what are postscript vector data, details can be seen.

A take-home from seeing the results is the episodic nature of weather. Mostly it is bouncing around as weather does but also there are sustained periods with less noise and perhaps floods or droughts, warm or chilly. The temperature data says we have recently had cool and then warm episode. Where this is notable it seems to last for around a year, as-if anything is a definite rule.

Temperature adjustments: simmering science scandal ?

Long-time critic of climate alarmism Christopher Booker has no doubt what the answer should be in his latest piece at the Telegraph:

When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.

Two weeks ago, under the headline “How we are being tricked by flawed data on global warming”, I wrote about Paul Homewood, who, on his Notalotofpeopleknowthat blog, had checked the published temperature graphs for three weather stations in Paraguay against the temperatures that had originally been recorded. In each instance, the actual trend of 60 years of data had been dramatically reversed, so that a cooling trend was changed to one that showed a marked warming.

MET office claims warmest UK year back to 1910

Rain: Is this cause for concern?

A few days ago Paul Homewood picked up an item where the Met Office seem to make a fuss about UK heat and wet, although Robert Ward seems to be the one fussing. Since I have have the precipitation data on hand what do I make of it?

“More Misleading Claims From The Met Office” (7th Nov)

This cites Yahoo News.

I’ll ignore the temperature, here is the precipitious matter ‘since records began in 1910 it has been the second wettest.’ [1]
Presumably more than 194 million tons of water dropped on London according to calculations by the British Rainfall Organisation [3]

The Met Office ploy is add the data January through end October and make that a year by year spot value.

ABSTRACT

Aims. We present a new model of total solar irradiance (TSI) based on magnetograms simulated with a surface flux transport model (SFTM) and the Spectral And Total Irradiance REconstructions (SATIRE) model. Our model provides daily maps of the distribution of the photospheric field and the TSI starting from 1878.

Global temperature and missing heat whereabouts update

The plot below needs little explanation. The globally average surface temperature hasn’t warmed in over 18 years according to the RSS satellite dataset.

 

Now, Some say the surface hasn’t warmed because the ‘missing heat’ has gone into the oceans instead of warming the surface.However, if we look at ARGO; the best data we have for ocean heat content (OHC) (before it got reworked in 2010 by dropping buoys showing cooling from the dataset) – we see that Ocean Heat Content actually fell from 2003 to 2008:

Where else could the heat have ‘hidden’? Well, the warmists claim it went deeper than the bulk of the ARGO system measures – below 700m, where uncertainty rises dramatically. However, they offer no plausible explanation of how energy is transferred through a 700m deep COOLING layer, in defiance of the second law of thermodynamics.
