...discredited hokey schtick...

LOL love it!

The average life span of someone living in Sub Saharan Africa is 45! Their lives are short and brutish. And this to please the neo-malthusians?! So much for the liberals clamor for social justice!

Never forget that the libs always have The Population Bomb in the back of their rarely used minds. That's why when they speak about 'humanitarian concerns' I don't believe a word they say.

@ #18 LOL

Those are some pretty funny guys (as well as sharp) on that forum. I may have to start reading their comments just to get a laugh-induced endorphin fix.

looks great

This is a GREAT article. I am in agreement with him pretty much. I am not a GW denier, nor a denier in the effects of CO2, I just question the HOW MUCH that the alarmists have been trumpeting for years now. It good to see some rationality returning to at least some of the scientists involved.

Great Post.

This comment takes on the issue ( I think ) of the validity of the ice cores:

The ice core record (Law Dome spliced to Mauna Loa) is a bit dodgy too.

Evidence for molecular size dependent gas fractionation in firn air derived from noble gases, oxygen, and nitrogen measurements

Huber et al 2005

http://icebubbles.ucsd.edu/Publications/Huber_closeoff_EPSL2006.pdf

6. Conclusions
The enrichment of elemental ratios near the close-off region measured in the firn air from Devon Island and NGRIP, can be modeled assuming a constant close-off fractionation factor between closed off air and open pore composition during air enclosure. The strong similarities found at both sites indicate a universal physical process causing this close-off fractionation. Our model approach
is able to explain and predict the general shape of the firn air profiles from various different sites. However, it fails when the firn density structure has impermeable layers that cause large non-diffusive zones at the bottom of the firn. This has to be implemented into a future model.

The bottom of the firn is critical. This is the inclusion zone where firn transforms to solid ice.

Close-off fractionation factors for different gases depend strongly on the diameter.

Except they use an inappropriate diameter. They use collision diameter (molecules colliding with other molecules) when they should be using kinetic diameter (the aperture size that will let a molecule pass, CO2 collision dia 39nm, CO2 kinetic dia 33nm).

The mass of the molecule is less important, since the effect on isotope ratios is very low. The critical size of about 3.6 Å [36nm] seems to be an upper limit up to which molecules fractionate during the close-off process in the firn.

CO2 will pass 36nm if kinetic dia is used.

A possible explanation for this could be the diffusion of molecules through channels in the ice lattice. From our findings we believe that the effect of close-off fractionation is nonexistent or at least very small for isotope ratios and for large molecules, like Xe, Kr, N2, CO2, CH4, and N2O.

They have only considered a simple sieving mechanism. Others, notably Ideka-Fukusawa et al describe a hydrogen bond breaking lattice distorting mechanism where CO2 passes through the ice latice.

This is an important confirmation for the integrity of polar ice cores as a climate archive of the ancient atmospheric composition of these gases.

I don’t think so. I would be interested in any comments on this either here or at CCG

This bears repeating at every available opportunity too.

The “correction”:-

……the average age of air was arbitrary decreed to be exactly 83 years younger than the ice in which it was trapped. The “corrected” ice data were then smoothly aligned with the Mauna Loa record (Figure 1 B), and reproduced in countless publications as a famous “Siple curve”. Only thirteen years later, in 1993, glaciologists attempted to prove experimentally the “age assumption”[10], but they failed[9].”

This is the dataset that ALL IPCC climate models use for initialization and subsequent simulations are based on, the results of which became the basis of govt policy.

There are now several independent pieces of evidence showing that the earth responds to the warming due to extra carbon dioxide by dampening the warming. Every long-lived natural system behaves this way, counteracting any disturbance, otherwise the system would be unstable. The climate system is no exception, and now we can prove it.

The person who wrote this may be a scientist, I don't know, but he makes an embarrassing mistake in technical language here.

Dampening is, I suppose, the use of water to knock down a fire or moisten a cloth.

The word for a dynamic effect that tends to decrease the amplitude of a system that's oscillating about an equilibrium value is damping, as in "damping constant" or "damping factor" or "damping coefficient."

That stuff on ice core gasses is way over my head. The incredible complexity of it says to me that it is certainly open to error and questions of interpretation. Which is just what that comment does made by someone who does have a handle on it. How many variables might there be in analyzing gasses trapped in ice for centuries?

I'm sure the analysis of what they have in hand is very precise (although that post seems to question exactly that) but have they thought of all the possible factors that could affect those gasses through the centuries? One unsuspected reaction could alter every conclusion they have come to.

"A small cabal of rent seeking scientists at the CRU in conjunction with their gravy train riding counterparts in the U.S. (Hansen and company) engineered this scam."
Eddy sounds like a lot of us here. The only third world countries that want in are those at the receiving end of the hand holding the money.
China and Russia have stayed as far as they can from this scam. They have no pressure to participate. Why give their money away to have nots.

Thanks Ernest.

[Ernest_at_the_Beach]

Over my head too....but it certainly points out that what goes on down below the ice cap isn’t simple.

Bump....

Good article. Also some good articles linked at the author’s web site.

I like this one:
