In their latest report the authors point out: ‘it is never mathematically proper to attempt to validate any theory embedded in a model using the model itself.’

As discussed last week, several reports have shown in the last year or two that carbon dioxide (CO2) does not significantly affect global temperatures, contrary to endless repetitions to the contrary by climate alarmists and the mainstream press.

Today some of the same authors of the reports discussed last week have released a new report that among other things makes a similar point using a different data set, making a total of 15 such data sets between the earlier reports and this new report.

Abstract
It is proposed that visitation by extraterrestrial spacecraft (UFO) alters the electromagnetic properties of the earth, its atmosphere, and its oceans and that these changes can cause global warming leading to climate change and thence to the catastrophic consequences of floods, droughts, severe storms, and sea level rise. An empirical test of this theory is presented with data for UFO sightings and surface temperature reconstructions for the study period 1910-2015. The results show strong evidence of proportionality between surface temperature and cumulative UFO sightings. We conclude that the observed warming since the Industrial Revolution are due to an electromagnetic perturbation of the climate system by UFO extraterrestrial spacecraft.

Surely a step in the right direction. The public is entitled to something better than smoke and mirrors when it comes to the use of science – or alleged science – to determine national policy. But the aim of objectivity is a tough one.
H/T The GWPF

Environmental Protection Agency (EPA) Administrator Scott Pruitt will soon end his agency’s use of “secret science” to craft regulations, reports Michael Bastasch.

“We need to make sure their data and methodology are published as part of the record,” Pruitt said in an exclusive interview with The Daily Caller News Foundation. “Otherwise, it’s not transparent. It’s not objectively measured, and that’s important.”

Making so-called ‘adjustments’ to existing temperature data, followed in some cases by adjustments to the adjustments, was never going to be a credible scientific method.
H/T The GWPF

A group of prominent scientists are calling for a global network of advanced weather stations that don’t need to go through controversial data adjustments, and it’s vindication for global warming skeptics, writes Michael Bastasch.

Seventeen climate scientists co-authored a research article published in the International Journal of Climatology calling for a global climate station network modeled after the United States Climate Reference Network (USCRN) to use as a baseline for data quality.

Hurricane Katrina, 2005 – The air pressure, another indicator of hurricane strength, at the center of this Category 5 storm measured 902 millibars, the fourth lowest air pressure on record for an Atlantic storm. The lower the air pressure, the more powerful the storm.

This is supported by Hurricanes – Science and Society, which says:
‘It is well accepted that the most influential factor in storm surge generation is the central pressure deficit, which controls the intensity of a hurricane, i.e. wind velocity and stress over the ocean surface and inverse barometric effects.’

The system for categorizing hurricanes accounts only for peak wind speeds, but research published in Nature Communications explains why central pressure deficit is a better indicator of economic damage
from storms in the United States, reports Phys.org.

“Sandy is the classic example. It was a very big storm, but in terms of maximum wind speed it was arguably not a hurricane,” said Dan Chavas, an assistant professor of atmospheric science at Purdue University who led the study. “If you looked at the central pressure deficit, you would have expected it to cause a lot of damage. But if you used maximum wind speed, as people usually do, you wouldn’t expect it to do the damage that it did.”

Central pressure deficit refers to the difference in pressure between the center of the storm and outside it. Pressure and wind speed have been used interchangeably to estimate potential damage from hurricanes for years, but the relationship between them has been a long-standing riddle in tropical meteorology.

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.

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.

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

blackbodies

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?

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.

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.

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.

Another instance of ‘adjustments’ completely distorting temperature history – from Paul Homewood.

NOT A LOT OF PEOPLE KNOW THAT

Tinganes, Tórshavn old town

Thorshavn, Faroe Islands

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

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…

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.

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.
