Aerm..  I know what a &quot;fraud&quot; is.. 

But could you please tell me from a to z what this particular fraud is all about?
I would like to understand 100% and i got the idea that you could answer.
I use this information to pass on i other blogs concearning the fraud of IPCC, and i would like to know exactly what this one is all about before using it.]]></description>

		<description><![CDATA[Indur Goklany points to one example of IPCC duplicity in its claims of increased global water stress as a result of AGW.

This is just one of many examples.  Others involve:
·	False claims on sea level rise
·	False claims on Antarctic ice sheet mass loss
·	False claims on Greenland ice sheet mass loss
·	False claims on Northern Hemisphere snow cover
·	False claims on surface vs. troposphere record 
·	False claims denying a distortion of the surface record due to the urban heat island (UHI) effect

These are some of the outright unruths in the latest set of IPCC reports.  In addition there are doubtful claims:
·	Questionable claims denying past warm periods
·	Questionable claims on solar forcing
·	Questionable claims on water vapor feedback
·	Questionable claims on cloud feedback
·	Questionable claims on tropical cyclones, droughts, heat waves and other extreme weather events

All of these false and questionable claims are used to “project” future changes, which are, by definition, also false or exaggerated.

IPCC has made no effort to provide an unbiased scientific view of our climate, but has concentrated its efforts on “selling” its own views and opinions on AGW and feeding the “policymakers” to whom its reports are directed a false and one-sided view of what it really going on.]]></description>

		<description><![CDATA[Frank,

In academia and science, fraud can refer to academic fraud – the falsifying of research findings which is a form of scientific misconduct – and in common use intellectual fraud signifies falsification of a position taken or implied by an author or speaker, within a book, controversy or debate, or an idea deceptively presented to hide known logical weaknesses. 

http://en.wikipedia.org/wiki/Fraud

the special about this case is that there is no way to justify or debate the difference between the report and the quoted references.

the problem here is - whom at IPCC can anybody write, call, email or sue to correct this report and make the correction public ?]]></description>

		<description><![CDATA[Mike86 you do understand that the Meacham station is in the coldest part of the Blue Mountains in Oregon with the station likely nailed to a tall lodge pole pine tree in the middle of a forest (and in most years, this station records the coldest temps of the northwast part of the US at that altitude), and the Pendleton airport station is on the tarmac.  The airport is ALWAYS hotter than the mountains.  Are you just funnin me?  Or do you really see a warming trend?!?!?!?!??]]></description>

		<description><![CDATA[Manfred, thanks for your writing.
Could you explain from scratch: What is the fraud all about?
I have an idea (!), but im not 100% sure.
Please if you could explain.

		<description><![CDATA[I think this thread deserves much more attention.

Global water stress has been the main AGW scare for this century.
(war for water, millions of people fleeing due to draughts, etc.)

And now we have to learn that the IPCC told the world and the policy-makers the exact opposite of the content of their own scientific references.

This is a case that climate sceptics, people without a scientific degree, even politicians and sincere AGW supportive scientists should easily agree. 

The facts are just too simple and quite impossible to dispute. It may technically not be a full lie, but it is simple and plain fraud.

This could be used as a lackmus-test for the IPCC processes (and maybe the condition of democratic pressand institutions):

- this error should be corrected and a press conference held
- the authors of this chapter should be sanctioned
- Review processes have to be changed.
- responsibilities have to be assigned
- the closed IPCC circles have to be opened to external input.]]></description>

		<description><![CDATA[Along the same line:
Sloan and Wolfendale&#039;s analysis of Forbush decreases (sudden, temporary decreases in galactic cosmic ray fluxes, as modulated by the Sun&#039;s magnetic field) was presented around the blogosphere as part of an argument that there could be no relationship between the Sun&#039;s magnetic field and cloud cover on the Earth.

The use of Forbush data to draw such a conclusion is disputed &lt;a href=&quot;//climatesanity.wordpress.com/2008/09/05/applying-monte-carlo-simulation-to-sloans-and-wolfendales-use-of-forbush-decrease-data/”&quot; rel=&quot;nofollow&quot;&gt;&lt;em&gt;here.&lt;/em&gt;&lt;/a&gt;

In fact the temp on the 18th at two weather stations here tied two other dates since records began.

In economics, we make a formal distinction between &quot;risk&quot; and &quot;uncertainty.&quot;  I&#039;m not sure this distinction is common in other disciplines, so I&#039;m not sure what the term means in the IPCC&#039;s mission, or how it is understood by scientists working in disciplines relating to climate change.  Usually, outside of economics, we see the distinction between &quot;risk&quot; and &quot;uncertainty&quot; blurred, and the two to refer to the &quot;probability of uncertain events.&quot;  &lt;em&gt;Usually&lt;/em&gt; the focus is on the &quot;probability of uncertain &lt;em&gt;adverse&lt;/em&gt; events.&quot;  Who worries about uncertain, but fortuitous events?  So there&#039;s a sense in which I see, and acknowledge, your point.

But not if I apply the rigorous distinction we draw between risk and uncertainty in economics.  &quot;Risk&quot; refers to events with measurable probability.  &quot;Uncertainty&quot; refers to the prospect of events whose likelihood is indefinite or incalculable.  Given all the hoopla in IPCC about how they use confidence interval data to assess likelihood -- such as &gt;66% is &quot;likely&quot; and &gt;90% is &quot;very likely&quot; and so on -- they would appear to be using &quot;risk&quot; in the formal sense as we use it in economics.  And that doesn&#039;t justify leaving out the positive impacts.

The IPCC assessment reports are classic examples of &quot;confirmation bias.&quot;  Wikipedia has a good article on the subject, including the following Tolstoy quote:

&lt;i&gt;&quot;The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.&quot;&lt;/i&gt;

In the end, I guess I come out in the same place.  The IPCC assessment reports are agenda-driven.  They are the product of a group of intellectuals who are firmly persuaded that they already know, without a shadow of doubt, that climate change is bad, and especially anthropogenic induced climate change.  All that remains is to prepare reports to influence policy makers of these foregone conclusions.  There is absolutely nothing scientific about this process, and scientists who appeal to the IPCC&#039;s assessment reports as evidence of scientific consensus are traitors to their profession.  We expect such behavior in politicians.  We should cringe in horror when we see it in those who call themselves scientists.]]></description>
