I respect your opinion and will try to refrain from using that word but please don’t discount the possibility it may be happening.

When someone uses Hollywood disaster footage without comment in a documentary to illustrate a crisis one is obliged to go hmmmmm.

And when the same political alliance describes a crisis then advocates actions that would actually worsen it as per their claimed cause of it (new turnpike tollbooths, removing hydro-electric dams), I can’t help but go mega-hmmmmm.

See the numerous accusations as in the following Google search:
Panda’s thumb lying
Lets set the example in origin’s discourse and oppose such frivilous rhetorical use of “lying”.

DLH,

What evidence would you accept that they (OK, some) are lying through their teeth– i.e. knowingly and with premeditation disseminating information that they know to be false, and –and to add to my cynicism– for the pursuit of personal money and power?

Frankly, I can’t see any other word for it.

Now, I grant that “they” is a rather broad term, and certainly there are those who are sincerely and passionately concerned about global warming. You can usually tell who they are because they are outspoken advocates of nuclear power.

And of course there are others who are not lying but merely stupid and followers of fashion.

But follow the money. To ignore that lying — in the ugliest definition of the word– is not being used by some in the pursuit of power and money, is naive.

Are the “adjustments” by NASA’s Hansen to “correct” for errors, or are they the bias that is creating “global warming”?

Next would be to show a plot of temperature vs precipitation

I did. There’s no pattern, as I pointed out above, the correlation is effectively zero.

Next would be to show a plot of temperature vs precipitation and to do an autocorrelation to check the correlation.

Major issues:
Is the temperature trend biased by
1) the “heat island effect”?
e.g., Parker and Fresno Airport
and How not to measure temperature, part 10
Note particularly the “careful” location of the temperature sensor near concrete and an air conditioner exhaust!

2) systematic bias in temperature adjustment.
e.g. see:
Petaluma CA

There are better analyses around, but these are a flavor to exemplify the issues.

However lay off the ad hominem accusation of moral perversity unless you have clear evidence to the contrary. cf your statement “To me, that is slam-dunk evidence that they are lying through their teeth about there being a crisis.”

They may be deluded and morally unaware of what they are doing.

To me, that is slam-dunk evidence that they are lying through their teeth about there being a crisis.
