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.

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.

Exactly. The title of the article is totally unjustified.

my favorite article on teh Eocene is G.Woillard's,
either in Science or Nature,
"Abrupt end of the Eocene interglacial *sensu strictu*,"
based upon her digs at Grand Pile' peat bog in France. now,
as for a 400Ky period during the Quaternary Period,
I don't get it.

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.

thus:
well, I've read about "warming" on a bunch
of the sol system planets; I am not a denierist, but
i do not accept the fuzzy-quantification
via computerized simulacra, which is more
about the refinements of *computer* science and
numerical methods (IEEE-754, -854 e.g.,
the first of which is an article in a 1980 issue
of *Computer* .-)

It is localised on the Earth

thus: more to the point, although there are plenty
of examplars of exoterrestrial "plate tectonics,"
they certainly seem to be *associated*
with oceans, the lunar *maria* e.g. -- thank *you*.

thus: just get rid of Minkowski's pants; I mean,
he's still dead & may not still need them.

thus: Fermat did not give a demonstration
of his soi-dissant "last" theorem, nor
did he make any other mistake, known to me, or
to Wiles et al ad vomitorium in Oxbridge,
Harry Potter PSes Nos. One & Two.
Fermat did not have a demonstration, period....
Solve my problem set, or GET AWAY FROM THE MATH.

thus: as so inclined, beg the question put,
dish-out to your flabbergasting http://so-called-theory,
that may be better than Newton's
"theory of light & its 0d rocky missiles
of ray-tracing Copenhagenschooler joking-around
about the God-am, unlooked-at cat & "universes,
plural (sic)," embrace the scare quotes
around "of light, going faster
in a denser medium, ignoring the brachistochrone and
the creation of 'the' calculus,
_Principia/ Book Two/ Section Two/ Scholium Two/
Paragraph Two_, not endquote.
(regards from Leonerd Cohen) ... AND MORE DOTS.

thus: you are in my "really, really boring would-

Nowhere in the text that Roger posted does it say that CO2 rose first,
causing temps to increase. This is the same deconstructing done by Al
Gore. They say "temps and CO2 rise hand in hand", which of course
does NOT say "CO2 rise caused temps to warm". You need to parse the
words of these creeps, they're merely trying to keep up the background
chorus of "AGW caused by CO2". It's inept propaganda, but it's all
they have left now that science has shown them to be full of ****.

The long-term warmth of the Eocene (~56 to 34 million years ago) is
commonly associated with elevated partial pressure of atmospheric
carbon dioxide (pCO2). However, a direct relationship between the two
has not been established for short-term climate perturbations. We
reconstructed changes in both pCO2 and temperature over an episode of
transient global warming called the Middle Eocene Climatic Optimum
(MECO; ~40 million years ago). Organic molecular paleothermometry
indicates a warming of southwest Pacific sea surface temperatures
(SSTs) by 3° to 6°C. Reconstructions of pCO2 indicate a concomitant
increase by a factor of 2 to 3. The marked consistency between SST and
pCO2 trends during the MECO suggests that elevated pCO2 played a major
role in global warming during the MECO.

That's certainly got the deniers out in force to try everything they
can to deny it. mind you, it's not much.

It's really interesting research. The first time that a warming 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.

Is this a joke? The is a news story, and it is written in a
particularly deceptive way. We read.

! Kiehl said another intriguing find from the study is that 40 million
! years ago water temperatures reached as high as 25 degrees Celsius
! in areas where today the water is close to freezing. “That is a
! completely different world than what it is today,� he said. “That
! is very intriguing from an Earth system perspective."

Forty million years ago the continents and oceans were all in
different places. Australia was connected to Antarctica, and the
poles were in different places too. There is no such thing as the
"same place" on earth 40 million years ago.

I read through this three or four times, and *nowhere* does is state
how high the carbon dioxide level was at the time. Without that
number the whole story is meaningless. I *think* *maybe* it was
six times the present concentration which would make it something
over 2000 ppm.

Life survived. The earth did not become a cinder.
Civilization would survive such conditions, and at the present
rate it would take 1000 years to get there. One thing I am sure
of is that we will not solving the problems of the next millennium
with today's technology: not unless technophobic creationists
and their green allies succeed in bringing on a new dark age.

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.
