The sudden event of 8200 years ago is likely another volcanic event or possibly caused by the emptying of Lake Agassiz. I really do not like to blame any variation on the Sun. Our sun is variable but of a low amplitude and otherwise super stable. It is a long shot explanation that has to be matched by equal events elsewhere outside the Northern Hemisphere.
Volcanoes
care wonderfully successful at wreaking the climate for a long while.
Better yet we do need to pin down exactly the major disturbances
post Pleistocene Nonconformity. They do show up in Indian
scriptures.
In
the meantime, this reminds us of just how warm the Bronze Age climate
really was. Rome got the echo.
As
I have posted from the beginning in 2007 linking CO2 to climate is a
serious blunder not slightly supported by geology and meaningful time
lines.
GIANT OF GEOLOGY/GLACIOLOGY CHRISTIAN SCHLÜCHTER THROWS CO2 CLIMATE SCIENCE INTO DISARRAY

Sensational
discovery of 4000-year old chunks of wood at the edge of glaciers in
Switzerland proves climate was warmer in the past than previously
thought. Distinguished geologist, Professor Christian Schlüchter,
condemns politically corrupt 'man-made global warming' scientists for
covering up the game-changing find.
P.
Gosselin (notrickszone.com) reports (June 09, 2014):
This
post is about an interview by the online Swiss Der
Bund here with Swiss geology giant Christian
Schlüchter titled: “Our society is fundamentally dishonest“.
In it he criticizes climate science for its extreme tunnel vision and
political contamination.
Geologist Sebastain
Lüning sent me an e-mail where he writes: “This is probably
the best interview from a geologist on climate change that I
have read for a long while. My highest respect for Prof.
Schlüchter.” Fritz Vahrenholt calls it “impressive”.
His
discovery of 4000-year old chunks of wood at the edge of glaciers in
Switzerland in the 1990s unintentionally thrust the distinguished
geologist into the lion’s den of climate science. Today the
retired professor and author of more than 250 papers speaks up in
an interview.
Almost
glacier-free Alps 2000 years ago
Early
in the interview Schlüchter reminds us that during Roman times in
the Alps “the forest line was much higher than it is today; there
were hardly any glaciers. Nowhere in the detailed travel accounts
from Roman times are glaciers mentioned.” He criticizes today’s
climate scientists for focusing on a time period that is “indeed
much too short“.
In
the interview, Schlüchter recounts how he in the 1990s found a
large chunk of wood near the leading edge of a glacier. The chunk of
wood, he describes, looked as if it had been dragged across a cheese
shredder. It was clear to Schlüchter that the specimen had to be
very old. Indeed laboratory analysis revealed that it was
4000 years old.
Next they found multiple wood fragments with the same age, all
serving to fill in a major piece of the paleo-puzzle. His conclusion:
Today where one finds the Lower Aare-Glacier in the Bernese
Alps, it used to be “a wide landscape with a wildly flowing
river“. It was warmer back then.
Until
the 1990s, scientists thought that the Alps glaciers had been more or
less consistently intact and only began retreating after
the end of the Little Ice Age. Schlüchter’s findings showed
that glacial retreats of the past also had been profound.
This
threw climate science into chaos and it remains unreconciled today.
Ice-free
5800 of the last 10,000 years
But
not all scientists were thrilled or fascinated by Schlüchter’s
impressive discoveries. He quickly found himself the target of scorn.
Swiss climate scientist Heinz Wanner was reluctant to
concede Schlüchter’s findings. Schlüchter tells Der Bund:
I
wasn’t supposed to find that chunk of wood because I didn’t
belong to the close-knit circle of Holocene and climate researchers.
My findings thus caught many experts off guard: Now an ‘amateur’
had found something that the Holocene and climate experts should have
found.”
Schlüchter
tells of other works, which also have proven to be a thorn to
mainstream climate science, involving the Rhone glacier. His studies
and analyses of oxygen isotopes unequivocally reveal that indeed
“the
rock surface had been ice-free 5800 of the last 10,000 years“.
Distinct
solar imprint on climate
What’s
more worrisome, Schlüchter’s findings show that cold periods can
strike very rapidly. Near the edge of Mont Miné Glacier his team
found huge tree trunks and discovered that they all had died in just
a single year. The scientists were stunned.
The
year of death could be determined to be exactly 8195 years before
present. The oxygen isotopes in the Greenland ice show there was a
marked cooling around 8200.”
That
finding, Schlüchter states, confirmed that the sun is the main
driver in climate change.
Today’s
“rapid” changes are nothing new
In
the interview he casts doubt on the UN projection that the Alps will
be almost glacier-free by 2100, reminding us that “the system is
extremely dynamic and doesn’t function linearly” and that
“extreme, sudden changes have clearly been seen in the
past“. History’s record is unequivocal on this.
Schlüchter
also doesn’t view today’s climate warming as anything unusual,
and poses a number of unanswered questions:
Why
did the glaciers retreat in the middle of the 19th century, although
the large CO2 increase in the atmosphere came later? Why did the
earth ‘tip’ in such a short time into a warming phase? Why did
glaciers again advance in 1880s, 1920s and 1980s? [...] Sooner or
later climate science will have to answer the question why the
retreat of the glacier at the end of the Little Ice Age around 1850
was so rapid.”
On
science: “Our society is fundamentally dishonest”
CO2
fails to answer many open questions. Already we get the sense that
hockey stick climate claims are turning out to be rather sorrowful
and unimaginative wives’ tales. He summarizes on the refusal to
acknowledge the reality of our past: “Our society in fundamentally
dishonest“.
“Helping
hands for politicians”
In
the Der Bund interview Schlüchter describes a meeting
in England that turned him off completely. The meeting, to which he
was “accidentally” invited, was led by “someone of the
East Anglia Climate Center who had come under fire in the wake of the
‘Climategate’ e-mails“:
The
leader of the meeting spoke like some kind of Father. He was seated
at a table in front of the those gathered and he took messages. He
commented on them either benevolently or dismissively. Lastly it was
about tips on research funding proposals and where to submit them
best. For me it was impressive to see how the leader of the meeting
collected and selected information. For me it also gets down to
the credibility of science. [...] Today many natural scientists are
helping hands of politicians, and no longer scientists who occupy
themselves with new knowledge and data. And that worries me.”
Schlüchter
adds that the reputation of science among young researchers is
becoming more damaged the more it surrenders to politics. He
indirectly blasts IPCC chief scientist Thomas Stocker:
Inventing
the devil was one of man’s greatest inventions ever achieved. You
can make a lot of money when you paint him on the wall.”
Northern
hemisphere still gripped in ice age mode
Schlüchter
also says that the northern hemisphere is still in the ice age
mode and that the glaciers during the Roman times were at least 300
to 500 meters higher than today. “The mean temperature was one and
half degree Celsius above that of 2005. The current development is
nothing new in terms of the earth’s history.”
At
the end of the interview Schlüchter says that solar
activity is what is sitting at the end of the lever of change, with
tectonics and volcanoes chiming in.
Professor
Niklaus Ammann adds:
“Good
to hear from Christian Schlüchter (once he was my student – and a
brilliant one). My thesis work from 1972 gave lots of proof for
mountain forests in the Grimsel (Unteraar- and Oberaar-Glacier) with
a rich forest flora.”
