Research Paper Withdrawal by the Journal Advances in Space Research  

peer-reviewQ1: As succinctly as possible, could you tell me why you chose to publish this work under a pseudonym?

A1: We adopted pseudonyms as a measure of last resort as we could not get an unbiased and fair review from scientific journals under our real names. This is explained in more details in the attached letter we sent to the chief editor of the Journal Advances in Space Research (JASR) on Sep. 17, 2015. In brief, our real names became known to the climate-science blogosphere in 2012 when a poster, which we presented at an International Climate Conference in Denver in 2011, became available online and caused broad and intense discussions. When we later tried to publish elements of this poster as separate articles in scientific journals, we discovered that journal editors and reviewers would reject our manuscripts outright after Googling our names and reading the online discussion. The rejections were oftentimes justified by the journals using criticisms outside the scope of the manuscript at hand.  On two occasions, journal editors have even refused to send our manuscripts for review after reading the blogs and realizing the broader theoretical implications of our results, although the manuscript itself did not explicitly discuss any new theory. For example, our first paper was rejected 4 times by different journals while submitted under our real names before it was finally accepted by SpringerPlus after submitting it under pseudonyms.

The following demonstrates that Metoffice Hadcrut4 is a restatement of the NOAA El Nino index. It’s based on the conjecture that not only do El Nino events have an immediate effect on world temperature but also the clustering of El Nino or La Nina events have a cumulative effect on the worlds temperature. Ian Wilson and Paul Vaughan have provide the frame work to show that El Nino events are governed by the interaction of the Sun and Moon coupled with the hemispherical asymmetry of the Earth’s surface properties. The climate variation is driven by the ratio in strength and frequency of El Nino to La Nina events.

Are we anywhere close to really understanding the strength of natural climate variation and how it works?

We can easily overlook that most temperature measurements are taken on land, but over 70% of the Earth’s surface is deep water.

Climate Research Unit, University of East Anglia

The Climatic Research Unit (CRU) was established in the School of Environmental Sciences (ENV) at the University of East Anglia (UEA) in Norwich in 1972.

The CRU has collected, collated and archived global climate data for over 40 years.

CRU temperature data

In 1987, the American Meteorological Society published a paper by Stanley Grotch of the Lawrence Livermore National Laboratory, University of California, that assessed the robustness of the CRU dataset for land and other datasets.

Monthly Weather Review, Volume 115 No. 7, July 1987, ISSN: 0027-0644; eISSN: 1520-0493

Abstract

Three data bases of gridded surface temperature anomalies were used to assess the sensitivity of the average estimated Northern Hemisphere (NH) temperature anomaly to: 1) extreme gridpoint values and 2) zonal band contributions. Over the last 100 year, removal of either the top or bottom 10% of the gridpoint anomalies in any year changes…

There’s been a lot of loud rhetoric flying around about the update to the RSS satellite temperature series. What it actually amounts to is a consolidation of the satellite temperature measurement effort.

The two time series are now in good agreement and exhibit a warming rate of 0.13K/decade during the 1980-2015 period.

My thanks to talkshop reader Jamal Munshi for alerting me to his paper on ozone and aerosols. It makes a strong case for viewing the ozone level above the Antarctic as a special case due to its unique geography, calling into question conclusions about human emissions drawn by scientists and acted on by the Montreal protocol. This is important as this agreement has been used as a template for ‘climate action’ subsequently.

ABSTRACT:

The overall structure of changes in total column ozone levels over a 50-year sample period from 1966 to 2015 and across a range of latitudes from -90o to +71o shows that the data from Antarctica prior to 1995 represent a peculiar outlier condition specific to that time and place and not an enduring global pattern. The finding is inconsistent with the RowlandMolina theory of chemical ozone depletion. 1 1.

INTRODUCTION

In 1971, renown environmentalist James Lovelock studied the unrestricted release of halogenated hydrocarbons (HHC) into the atmosphere from their use as aerosol dispensers, fumigants, pesticides, and refrigerants. He was concerned that (1) these chemicals were man-made and they did not otherwise occur in nature and that (2) they were chemically inert and that therefore their atmospheric release could cause irreversible accumulation. In a landmark 1973 paper by Lovelock, Maggs, and Wade he presented the discovery that air samples above the Atlantic ocean far from human habitation contained measurable quantities of HHC (Lovelock, Halogenated hydrocarbons in and over the Atlantic, 1973). It established for the first time that environmental issues could be framed on a planetary scale and it served as the first of three key events that eventually led to the Montreal Protocol and its worldwide ban on the production, sale, and atmospheric release of HHC (UNEP, 2000).

Reblog from Clive Best’s site.

The basis of IPCC predictions is that any moderate warming caused by increased CO2 levels is enhanced by more evaporation from the oceans. Water vapour is itself a strong greenhouse gas and this increase results in a large “positive feedback” boosting climate sensitivity to a doubling of CO2 as high as 6C.
This is all just  theory however, so it is important to observe whether water vapour in the atmosphere has actually increased or not in response to increasing CO2. The data shown below are from the NASA NVAP [1] project based on radiosonde, TIROS,TOVS & SSM/I satellite based data. This data was kindly brought to my attention by Ken Gregory [2].

Fig 1: total Precipitative water vapour in 3 levels in the atmosphere im mm. The 3 curves are Northern Hemisphere, Southern Hemisphere and the “Global average” – see 2) below.


The data from NVAP shows little change in  water vapour from 1988 until 2001 at all levels in the atmosphere.  If anything a  small decrease in the important upper atmospheric layers  in the detail shown below Fig1b.

Met Office station data release

Posted: December 30, 2015 by tchannon in climate, Dataset, Surfacestation, weather

I am making available all the data collected from Met Office Datapoint for UK land stations.

Example of data processed to show deviations.

This is hourly from 22nd July 2014 through 28th 31st Dec 2015, missing, etc. excepted. The data has been processed into time series with missing data filled with not available marks and also the verbatim datapoint XML as received.

A Talkshop page has been added, can get to it via top menu Portal, direct link here.

This ought to be a gold mine for those able to work on data. Millions of datapoints. The Met Office do not archive this immediate data for public access so whilst there are defects, you’ll have trouble finding this elsewhere.

The last line of the 1995 email was withheld. Here it is

Our daily series is anchored to the monthly one so that
each months average calculated from the daily data equals its value
in Manleys monthly series.

The Met Office promote “Hadley Centre Central England Temperature” and HadCET but avoid “Manley CET”. There was and is no daily Manley CET. The Met Office made one up, adjusting daily figures to average the Manley CET monthly value exactly.

January 1974 onwards there is no Manley CET data to constrain Met Office daily figures.

From the dept of unsexy climate headlines we get news that there’s no news so far as precipitation is concerned. A new paper which examines a HUUUUGE number of records worldwide finds that there’s no trends anywhere of any significance from 1850. So much for dire warnings of increased droughts and floods due to extra CO2 which DO grab the headlines.

Changes in annual precipitation over the Earth’s land mass excluding Antarctica from the 18th century to 2013

 
Highlights

Over 1½ million monthly precipitation totals observed at 1000 stations in 114 countries analysed.

Data record much longer than 3 recent conflicting studies that analysed a few decades of data.

No substantial difference found for stations located at northern, tropical and southern latitudes.

No substantial difference found for stations experiencing dry, moderate and wet climates.

No significant global precipitation change from 1850 to present.

Time for the NOAA to front up and explain to US public representatives how it came up with its own temperature data that ran counter to everyone else’s, as GWPF reports.

Scientists and top officials from the National Oceanic and Atmospheric Administration have agreed to start interviews akin to depositions this week with House investigators, who are demanding to know their internal deliberations on a groundbreaking climate change study.

But the interviews may not be enough to placate the chairman of the House science committee, a global warming skeptic who last week stepped up the pressure on the Commerce Department to comply with his subpoena for e-mails that NOAA has refused to turn over.

Era ending for Martin’s Booty

Many people have wandered through the wonderland Martin created during the early years of the world wide web. His painstaking construction of an annotated weather timeline from ancient times up to today.

Booty Meteorological Information Source

IMPORTANT: Some elements on this web site will continue to be maintained as long as I am able – mainly the West Moors local weather data: however, the ‘Weather in History’ section will have to be ‘frozen’ now as I can no longer access the ‘raw data’ to add-to / amend the entries. However, I’m pleased to report that the British Library have offered to archive the entire site (with the ‘Weather in History’ files embedded) and this will mean that the data will be available as long as that organisation is in being: the host web site is HERE: enter the search term ” Booty Meteorological ” into the text box to find the data.

The 'before' version of sunspot numbers [Credit: Wikipedia]

The ‘before’ version of sunspot numbers [Credit: Wikipedia]

This result has been at least half-expected ever since the ‘revision’ of sunspot numbers was announced. The phrase ‘desired outcome’ springs to mind.

The Sunspot Number is a crucial tool used to study the solar dynamo, space weather and climate change, reports Phys.org. It has now been recalibrated and shows a consistent history of solar activity over the past few centuries. The new record has no significant long-term upward trend in solar activity since 1700, as was previously indicated. This suggests that rising global temperatures since the industrial revolution cannot be attributed to increased solar activity.

The analysis, its results and its implications for climate research were made public today at a press briefing at the International Astronomical Union (IAU) XXIX General Assembly, currently taking place in Honolulu, Hawaii, USA.

NOT A LOT OF PEOPLE KNOW THAT

Hadcrut4 data coverage

Posted: June 19, 2015 by tchannon in Analysis, Dataset

I’ll give the Met Office / Hadley / CRU some due, at least there are signs of actual data.

What-if a list of the dataset grid cells with data from the start Jan 1850 to current is computed? Where are these and what does the data look like?

Image

Figure 1, A fragment in time of the entire consistent Hadcrut 4 gridded data, weighted data as per computing a global mean.

This suggests the reputed bad winters during WWII. Computing the global equivalent would need the weighted mean completing, sum and then divide by the sum of weights. Unweighted (not shown) is similar except the winter 1944 has a hot peak, ie. largely a polar matter. There again without global data is any of this valid?

These Antarctic headlines are becoming almost routine, but still worth noting in view of all the propaganda telling us the world is supposed to be warming.

This is a comparison of data for the month of May only, stretching back to 1979. In the files linked at the end of the reportingclimatescience.com report (see ‘Source’ in original), there are separate figures for ‘extent’ and ‘area’, with an explanation of the difference (see Arctic file).

The lowest May figures (since 1979) for both polar regions were recorded in 2006, but the Antarctic was 12% above the long-term May average this year.

Report: Antarctic Sea Ice Sets New High In May.

Note the progression from cycle 21 to 24:

Graphical comparison of cycles 21, 22, 23 and 24 (last update December 1, 2014)

Similar cycles 12, 14, and 16 had lower peaks than cycle 24, and similar cycles 10, 12, 13, 14, and 16 all had earlier peaks:

The UK Met Office / Hadley Centre (Met Office) / Climatic Research Unit (UEA) construct and publish global time series for temperature based on published 5 degree gridded. How this is derived from land meteorological station readings and ship board for sea surface temperature is unclear. The gridded to eg. global is a simple (cosine) weighted average which takes into account the variable area of a linear grid representing a sphere.

I have put together maps showing the data counts for decades over a world shore outline. These are provided as vector plots (master work), PDF, or for casual looks, PNG. The results are disturbing and particularly in the light of the Met Office producing 100 different versions of HadSST3. “Each of the following files is a zip archive containing ten realisations of the HadSST3 data set. There are 100 realisations in total.”

Do I detect obfuscation, flapping for distraction?

[update] Roger Andrews has pointed out this work ought to use HadSST2, my mistake. I’m not sure what to do about this, updating the files is not too difficult but is there a material difference? I’ve created new files and am looking at introducing the hadcrut4 data.[update]
