Study Finds CO2 the Culprit in Ancient Global Warming

Scientists describe an actual warming event rather than one
predicted by a model


By Catherine M. Cooney


Some 40 million years ago, the world experienced an extreme spike in
global warming. The heat was so intense that deep sea temperatures
rose by about 4 degrees Celsius. This enigmatic sultry period, known
as the Middle Eocene Climatic Optimum (MECO), marked a 400,000-year-
long heat wave in the midst of a long era of global cooling.


Now research published Nov. 5 in the journal Science suggests the
rise in surface sea temperature occurred during a time when
atmospheric carbon dioxide (CO2) levels were particularly high,
according to a research team from Utrecht University and the Royal
Netherlands Institute for Sea Research.


Doesn't mean co2 caused it. Especially if co2 follows temps.



First reported by U.S. scientists in 2003, the MECO warming period
has been documented by data from a smattering of sites around the
world. Our paper is among the first to show that CO2 concentrations
and the temperature varied hand in hand in that time, says Peter
Bijl, a paleoclimatologist at the Netherlands Utretcht University
and one of the paper s lead authors.


The study may help put to rest some of the doubts expressed about
today s climate models because it describes an actual warming event
rather than one predicted by a model, according to Jeff Kiehl, head
of the Climate Change Research Section at the National Center for
Atmospheric Research in Boulder, CO.

And your evidence for this claim is . . .


"Several recent papers have indeed *established that there is lag of CO2
behind temperature*. We dont really know the magnitude of that lag as
well as Barton implies we do, because it is very challenging to put CO2
records from ice cores on the same timescale as temperature records from
those same ice cores, due to the time delay in trapping the atmosphere
as the snow is compressed into ice (the ice at any time will always be
younger older than the gas bubbles it encloses, and the age difference
is inherently uncertain). Still, the best published calculations do show
values similar to those quoted by Barton (presumably, taken from this
paper by Monnin et al. (2001), or this one by Caillon et al. (2003)).
But the calculations can only be done well when the temperature change
is large, notably at glacial terminations (the gradual change from cold
glacial climate to warm interglacial climate). Importantly, it takes
more than 5000 years for this change to occur, of which *the lag* is
only a small fraction (indeed, one recently submitted paper Im aware of
suggests that the lag is even less than 200 years). So it is not as if
the temperature increase has already ended when CO2 starts to rise.
Rather, they go very much hand in hand, with the temperature continuing
to rise as the the CO2 goes up. In other words, CO2 acts as an
amplifier, just as Lorius, Hansen and colleagues suggested.

event in the past has been attributed to CO2 without having to
model its effect. This is what patient, careful research does. It
adds to the knowledge base and it's yet another piece of research
that makes outright climate deniers just look stupid.

What did it say, then James? (This'll be interesting).


You'll have to read what you wrote. Oh, wait. You just pull stuff out of
your ass and peck it in.

Study Finds CO2 the Culprit in Ancient Global Warming

Scientists describe an actual warming event rather than one
predicted by a model


By Catherine M. Cooney


Some 40 million years ago, the world experienced an extreme spike
in global warming. The heat was so intense that deep sea
temperatures rose by about 4 degrees Celsius. This enigmatic
sultry period, known as the Middle Eocene Climatic Optimum
(MECO), marked a 400,000-year- long heat wave in the midst of a
long era of global cooling.

You could try reading the abstract, or better still the paper itself,
instead of expecting a newspapaer article to give you all the science
contained in the paper. Or you could think the newspaper article is
the full science.......which you probably do anyway, which is why you
are criticising it for not giving you it.


I was criticizing the newspaper article, not the science. If I dug
for it, I am sure the estimated eocene CO2 concentration is somewhere
in the scientific papers. The newsworthiness of the story depends on
the atmosphere of fear built up in the media. That is what I am
countering.

Did the newspaper article reference the scientific papers? No, it did
not.

The post was divided into two parts. It was not clear to me that the
second part is related to the first. The first part only talks about
the Reuters story. The article in Science requires payment, so I
am not going to read it. Maybe they should change the name of the
mag from *Science* to *Esotericism*.

Default Increased Atmospheric CO2 During the Middle Eocene

sorry, about mistaking Eocene with Eemian (interglacial,
the one before this-here Holocene, if it still is on .-)
good quote, abovesville;
the difficulty is especially noted, re ice cores etc.,
on the http://21stcenturysciencetech.com site,
over quite a few articles. (sorry, if they seem
to be Denierists .-)

thus:
if you'd put it into an English wordproblemma,
which is all that mathematics really is
-- in terms of the quadrivium, of course,
or "maths" -- maybe I could tell,
where you are wrong about the patent-office inspector
-- light grounding in engineering, eh? --
amendation (with Poincare' etc. etc.) of galilean rel.

really simple, without Minkowski's pants on, or
Alfred's reification of Fig Newton's "theory"
of corpuscles, absolutely imploded by Young,
Fresnel, Liebniz etc. etc. I mean, I guess,
it *is* the unofficial, secular, Second Church
of England; eh?

thus: solve Fermat's problem set, or
get the **** away from the math (see the sig;
I'd suggest beginning with the "reconstruction
of euclid's porisms," in Geometrical Fragments
of *L'OEuvre* .-)

thus: seems like guys arguing, who believe in a)
Minkowski's pants, and b)
that "photons" are zero-dimensional branes, because
herr doktor-professor, patent-office inspector, said,
So, and the Nobel Cmte. also said, 'Tis so,
we must reify Fig Newtons "theory" of corpuscles
in the year cce 1905 -- praise-be! (just be thankful,
there is no God-am such prize in mathematics and/or
economics .-)... guys, who probably also fell
for Lord Berty's sillygistic "paradoxes," I wonder.

one should give *some* of the doubt
to herr doktor-professor, patent-office inspector,
by taking a look at a recent, totally hagiographical
book, _Einstein's Mistakes_, a blow-by-blow account
of his publications & correspondence, certain
to make the typical/adolescent "antisemite" or "self-
abnegating Jew" want to throw it into traffic.

myself, I got so woozy, just skinmming, that
I had to grab my book-holding hand & force it
to put it back on the shelf at the bookstore,
sort of like that funny movie
about Carl Sagan's mentor (his own version,
call PBS .-)

thus: like, HOPE was an acronym?... also, A.T.M.
(voting-machine) certainly is (so, take a guess).

two parts, brought to you by the courtesy
of the owls in Harry Potter PS#1, Oxford.

thus:
I found an incredibly deep. mathematical treatise
on the power of wind.drag, but
it made no definitive formula, like "fourth-power
of delta-velocity; so, there. endquote
