Many years ago, the debate about Anthropogenic Global Warming moved away from science to become highly political, essentially a pseudo-religion; in some regions also splitting populations along ideological lines. As is typical in such circumstances, facts become twisted; myths are created; lies and exaggeration trump facts; and faith in authority displaces rational, critical thought. This document exposes and highlights some of the inconvenient facts and trickery such that policymakers, and the public, can engage in questioning of the ‘climate change’ orthodoxy and its associated agendas.

Preface

From the humble beginnings of a scientific hypothesis, Anthropogenic Global Warming (AGW) has become a world-wide ideology. Indeed in most parts of the world it has become a pseudo-religion; accepted without questioning. Like its spiritual cult counterparts it has become intolerant of inquiring minds with virtually all arguments being squashed by assertions from an essentially selfproclaimed ‘authority’; in this case the church of the United Nation’s Inter-governmental Panel on Climate Change (UN IPCC). This institution and the copious other bodies it has spawned have published, promoted and preserved a great deal of false and misleading information about climate over the last couple of decades; becoming increasingly outrageous during the last few years. It has influenced the attitudes of vast swathes of the Earth’s population and biased a myriad of diverse policies throughout the world.

Dam intriguing article regarding the influence of the number of stations on the global temperature measurement has been written by Ross McKitrick and published on his website here: The Graph of Temperature vs. Number of Stations. Looking at his graph, the eye is instantly drawn to the apparent correlation between the stations and temperature.

There is a huge step in the raw mean temperatures around 1990 with a synchronous change in the number of stations. The adjustments and gridding methods employed to create the accepted global temperature records, are reportedly satisfactory to deal with such data aberrations and on visual inspection there is no immediately obvious problem. However, that does not rule out the possibility that the gridded end product contains artefacts of the processing and/or character from the raw data that are not related to climate and that could potentially distort the overall picture. This brief communication describes a method, utilising the dataset from Ross McKitrick and Joe D’Aleo, to calculate a historic temperature record through modelling the relationship between raw mean temperatures and the number of stations.

Excerpts:
Towards the end of last year, 2009, an Epetition was created and submitted by Mike Haseler to the UK Government regarding the Climate Research Unit (CRU) at the University of East Anglia (UEA). Nearly 3300 signatures were attached to it and the Government responded on 24th March 2010. The petition request was: http://petitions.number10.gov.uk/UEACRU/

Quote: We the undersigned petition the Prime Minister to suspend the Climate Research Unit at the University of East Anglia from preparation of any Government Climate Statistics until the various allegations have been fully investigated by an independent body.

So here we have the revelation that GISS is inferior to CRU, some of the data is not used and adjustments are included, although the three sets agree on decadal scales over land. We need to remind ourselves that the Earth is two thirds covered by water, so what about the rest? But the CRU version is now in question and being investigated and an expert considers GISS to be inferior. Apparently these inconvenient facts are immaterial to the Government.

Next, let us finish with the final line of the petition request:

Quote: We call on the PM to suspend all further use of the climate research unit until all pertinent allegations have been investigated and any action (if any) has been taken.

This has been completely disregarded and thus goes unmentioned and obviously, without action. Business continues as usual at CRU.

I think you might be interested in my study of Arctic sea ice extent. I put most of it together some time back and have finally managed to revisit it adding some of the things that should have been there first time around. The data sources have not been updated since I wrote it originally.

It now contains calculations of difference between the satellites. Whilst the trend is a little on the high side, probably due to the apparent more rapid decline in the overlapping time frame, it does suggest that all the apparent Arctic sea ice extent decline might be accounted for by measurement drift.

How Fast is Arctic Sea Ice Declining?
by Jonathan Drake

Day after day we are bombarded with images of polar bears on ice bergs and collapses of ice sheet into the ocean with apocalyptic headlines that the Arctic ice will vanish within a few years. It is of particular interest that, according to Dr. Vicky Pope, head of Climate Change at the UK Met Office, “Recent headlines have proclaimed that Arctic summer sea ice has decreased so much in the past few years that it has reached a tipping point and will disappear very quickly. The truth is that there is little evidence to support this. Indeed, the record-breaking losses in the past couple of years could easily be due to natural fluctuations in the weather, with summer sea ice increasing again over the next few years.” Met Office: Stop misleading climate claims

So, on that basis, what is going on? Could there be some kind of misinterpretation of the data? Might someone have made a wild extrapolation? With these questions in mind the Arctic sea ice records are examined to see what, if anything can be learnt.

The two commonly cited measures for sea ice are extent and area. Many people are unaware that there are two different measures, let alone a difference or what it is and so a simplified definition would seem useful. Both are presently derived from satellite and calculated from images. Each pixel of the image is assigned an area.

I recently came across an article that linked to data for various analyses of carbon emissions. Of particular interest was the per capita emissions data for each nation in 2006. Why was it of interest? Well simply, it shows a very different picture to that normally presented regarding national emissions levels.
