Emphatic Blow To CO2 Warmists – New Study Shows A Clear Millennial Solar Impact Throughout Holocene
By Pierre Gosselin (reposted from No Tricks Zone with permission)
A new paper titled High-resolution sea surface reconstructions off Cape Hatteras over the last 10 ka appearing just recently in the AGU Paleoceanography Journal authored by Caroline Cléroux et al provides further, clear evidence of a major solar impact on climate during the Holocene. Hat/tip: http://kaltesonne.de/.
According to the paper’s abstract, the study presents high-resolution foraminiferal-based sea surface temperature, sea surface salinity and upper water column stratification reconstructions off Cape Hatteras, a region sensitive to atmospheric and thermohaline circulation changes associated with the Gulf Stream.
Now if I recall correctly, this was the region that Stefan Rahmstorf deemed not long ago as good enough to be used to represent sea level trend for the whole world.
The above authors focused on the last 10,000 years to study the surface hydrology changes under our current climate conditions and looked at centennial to millennial time scale variability. To do this, a seabed core was extracted off the coast of Cape Hatteras, North Carolina at a water depth of 620 m.
They observed opposite evolutions between the conditions off Cape Hatteras and those south of Iceland, known today for the North Atlantic Oscillation pattern. Around 8.3 ka and 5.2–3.5 ka, they reconstructed positive salinity anomalies off Cape Hatteras. For the 5.2–3.5 ka period they demonstrated that the salinity increase was caused by the cessation of the low salinity surface flow coming from the north.
What’s behind the anomalies? They found that variations were in sync with total solar irradiance. The abstract states (emphasis added):
Wavelet transform analysis revealed a 1000-year period pacing the d18O signal over the early Holocene. This 1000-year frequency band is significantly coherent with the 1000-year frequency band of Total Solar Irradiance (TSI) between 9.5 ka and 7 ka and both signals are in phase over the rest of the studied period.”
The paper’s introduction has a few sentences that the IPCC really needs to take note of (emphasis added):
The last decade of paleoclimate research has shown that the Holocene is not the stable, climatic event-free period as previously thought: both external and internal (oceanic) forcings have caused major climatic changes. [...] On a shorter time scale, observations over about the last 50 years show interannual and decadal climate change. These fluctuations probably persisted throughout the Holocene, together with centennial to millennial variability.”
Dr. Sebastian Lüning writes at the Die kalte Sonne site:
The new findings once again clearly underscore that the last several thousands of years are characterized by natural temperature cycles that are controlled by fluctuations in solar activity (see p. 68-75 in ‘Die kalte Sonne’). The logical continuation of these natural cycles through today shows that an important part of the warming of the last 150 years has to be attributed to the increase in solar activity. It is not a mere coincidence that the last decades have been the most solar active of the last 10,000 years.
The climate models used by the IPCC are not able to reproduce these millennial cycles because they assign only a very small climate impact to the sun. Also the recently introduced new climate model from the Max Planck Institute in Hamburg suffers from the same deficiency, and thus the results of that model are essentially unrealistic.”
In layman’s terms: crap in, crap out.
Once again yet another study that emphatically shows that climate changed in the recent past (while CO2 was stable), and that these changes were in sync with solar activity.
Thanks E.
Think that’s the same guy that said the Himalaya glaciers were all going to melt?
Then, of course, there's the Mormon who keeps praying that every time it really clouds up over here near the Temple in Kensington that Jesus is coming back. Hope he never gets in charge of the UN-IPCC ~ not that his belief is wrong, but the local fog problem (which can be considerable) would be part of every major climate story.
Well not many of the AGW stories have actual back-up data to begin with. :)
Speaking of fog, we had fog last week! It’s been so dry, it just hasn’t materialized in what seems like a year or so. Rather strange being 10-15 miles from the Gulf.
I have looked at this article three times and I something just blocks me from being able to “get it”. I know part of that is this ^#*%! tendency of some paleo-climate/geology fields to run time backwards - graphing in such a way that current dates are on the left and older times on the right. That can really mess up my mind if I’m not completely with it that day. However, I don’t think that is my problem with this particular study. I just am unable to follow the logic in the article, or abstract. Often I will get a hold of the original paper in this type of situation, but I just don’t feel in a good state of mind generally to do that with this paper.
I think this is a frightening chart. Not only has there been considerable variation since that area on the right (which was during the last big ocean level increase ~ which ended about 8500 years ago), it's lately (last 1500 years) been getting colder, and is now on a steep decline.
Yeah, these guys will stroke the AGW crowd for funds by saying "Oh, yeah, brutha' and that warming stuff, oh, yeah, this has nothin' against it oh, no" because they know none of those guys know how to read a chart that covers 10,000 years!

The SUN?! NO WAI!!
The Earth has a built in equilibrium which has allowed life here to flourish, its called the greenhouse effect, and it is of course an equilibrium. It is what allows earth and its climate to endure the swings in solar out put.
Gee. What a concept eh?? LOL
