The Dependable Warmer

During the middle of the Eocene, about 40 million years ago, a transient
warming event interrupted the long-term cooling trend that had been in
progress for the previous 10 million years. Bijl et al. (p. 819; see the
Perspective by Pearson) constructed records of sea surface temperature
and atmospheric CO2 concentrations across the warming period. It appears
that vast amounts of CO2 were injected into the atmosphere, and a sea
surface temperature increase of as much a 6°C accompanied the
atmospheric CO2 rise.

"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".

From January to July where you live there is a huge temperature
increase and you can't explain it,there are only two motions involved
and you can't comprehend the separate daily and orbital motions to
conclude that seasonal temperature fluctuations are best described
using daily rotation to the central Sun that causes the daylight/
darkness cycle and the separate orbital daylight/darkness cycle best
appreciated through understanding the cycle at the polar coordinates
where 6 months of daylight is followed by 6 months of darkness due
solely to the orbital behavior of the Earth.

That is the only dependable warmer you need to consider before
launching into a minor atmospheric gas.

The angle of incident sunlight goes from less than 25° above the
horizon around noon on the winter solstice to more than 71° above
the horizon around noon on the summer solstice. My part of the
world absorbs way more sunlight (and IR) causing warmer temperatures
in the summer than winter.

These are things you should have learned in school, Gerald.

A necessary condition for this angular change is the fact that the
rotational axis of the earth is tilted with respect to the normal
of the ecliptic by roughly 23.5° .

Once you discover that the reasons behind the 6 months of darkness
followed by 6 months of daylight at the polar coordinates (where daily
rotation is residual) arises solely from the orbital behavior of the
Earth,you are half way to explaining the temperature fluctuations at
lower latitudes where it mixes with daily rotation.As the orbital
daylight/darkness cycle is now common knowledge I had hoped even an
anonymous reader would take a crack at normal language and explain it
to you instead of that robotic statement you just made.

Remember Kelleher simulates stupidity to annoy, frustrate and
generally wind-up people.

If you don't believe me let's do a little test.

So Gerald please explain in extreme detail what you mean by this.

Oldest lesson in the world is that if you can't be trusted with
fundamental things,you can't be trusted with complex issues.There are
only two motions involved and you refuse to recognize the orbital
daylight/darkness cycle where there is a single day/night cycle
arising from the orbital motion of the Earth and coincident with an
orbital period.The temperature fluctuation between January and July
where you live,excluding geographical modifications,is due to the
length of time you latitude spends in solar radiation or in the
orbital shadow of the Earth and that depends on acknowledging the slow
and uneven orbital turning of the Earth to the central Sun.

No point in wasting time explaining that you are trying to explain 6
month temperature fluctuations referencing the poles to the Sun
whereas the correct approach is to begin with temperature fluctuations
at the equator and see the greater fluctuations occur in tandem with
the greater latitudinal variations between daylight and darkness
towards polar latitudes and that means looking at the changing
relationship between the Earth's two daylight/darkness cycles and
their respective motions.You refuse to acknowledge the orbital
daylight/darkness cycle but then again you can't even recognize the
correspondence between daily rotation and the daylight/darkness cycle
as you believe there are 366 1/4 rotations in a year.

You probably wanted to say 'tilt to the orbital plane' like you used
to do but I guess you have caught up with the analogy of broom and
central object in imitating the orbital behavior of the Earth.

It has long be known there were two other spikes in temperatures, one
at 45Mya and another at 39.5MYa (not large ones, these are relatively
small compared to others but nonetheless).

However this study has CO2 levels which are way, way off the charts.

One period is 6,918 ppm (ranging from 5,560 to 8,250 ppm)

I've noticed before this CO2 method produces wild swings in estimates
(including values near Zero) so I have stopped using the numbers
produced by it.

Off the charts you say !,tell me,Sam indoctrinates these poor students
in Ames,Iowa where there is a 60 degree F differential between January
and July -

Many people come to this forum hoping to skip by fundamental
astronomical principles and facts but soon leave deflated as their
inability to explain basic correspondences trip them up so,to spare
you the usual squirming,when you comprehend fundamental temperature
variations at a human level and within human time frames,in this case
only 6 months,then and only then can you consider any other input.

Empiricists are good at reactions but offer little by way of
discussion or responses as it reveals how little people comprehend
climate,weather and any difference between them.Astronomers would have
put a stop to that CO2 racket long ago but currently they refuse to
use their doctorates or interested adults with talent have yet to
appear.As for you and CO2,well....
