You've been told?
Ok, let me when I can observe sunrise and sunset in the North,
the thought of the sun overhead at the Pole should be interesting.
Now, what can I tell you... ermmm... you owe me 1000. I'm
sure you believe it, so pay up.

Actually you are making a good point. Orbital effects on climate follow
from relatively simple and firmly established laws of physics. The laws of
motion ignore politics.

I can look it up. It's called the Milankovitch Cycle

http://en.wikipedia.org/wiki/Milankovitch_cycle

Allow me to do your research for you:

"Two caveats are necessary: firstly, that anthropogenic effects (global
warming) are likely to exert a larger influence, at least over the
short term; and secondly that since the mechanism by which orbital
forcing affects climate is not well understood, there is no very good
model relating climate to orbital forcing.

An often-cited 1980 study by Imbrie and Imbrie determined that
"Ignoring anthropogenic and other possible sources of variation acting
at frequencies higher than one cycle per 19,000 years, this model
predicts that the long-term cooling trend which began some 6,000 years
ago will continue for the next 23,000 years."[7]

More recent work by Berger and Loutre suggests that the current warm
climate may last another 50,000 years.[8]"

So

The cycle is completely unable to account for any of the recent
dramatic warming because it is a slow, steady and marginal effect,
compared with the smoking gun that all the coal-funded idiots on here
are determined to ignore.

The north pole was "pointing more toward the sun" on Jun 21st, known
as the solstice. It's effect on climate is so dramatic we sorcerers and
fortune
tellers study the stars and give it a special name, "Summer".

I'm not really in the prediction business, horology isn't my style, but if
you cross my palm with silver I can say with some certainty it will happen
again shortly after Winter. The more silver (or gold) you give me, the
more accurately I can predict it for you. I'll also need a sphere of crystal
and a cup of tea (without the tea bag) because tea bags are a modern
invention that preclude reading tea-leaves properly.
Chinese tea is preferred to India tea, it has more karma. Oh, and I also
need a single gold ear-ring, I don't have one of those either.

That old imposter Nostradamus failed to predict man would land on
the moon, which is why so many kids today don't believe it happened.
If he'd done his job properly we wouldn't be in this situation.

Precession changes the direction of the Earth's axis, currently aligned
with Polaris, but doesn't change the 23.6 degree tilt. The other effect
on climate is indeed precession, the extremes being when the summer
tilt is at perihelion and 12,000 or so years later at aphelion.
This could be the major influence on periodic ice ages. Man plays
no part in it. Nutation IS a change in the tilt, but is quite small.
Recorded history doesn't go back far enough to give us much
information, but it is almost certain that the fabled flood of Noah
was indeed world wide and the waters rose to their present level
when the Northern ice cap melted away from Canada and Siberia.
A crude estimate of a 2 mile thick ice cap (same as Antarctica)
stretching as far south as Youngstown, Ohio would yield a
sufficient volume of water for sea level to change by 300 feet.
The scree deposited at Morraine State Park in Pennsylvania
marks the end of a glacier, rock from Canada was deposited there.

Those alarmed by global warming should look even further ahead
to the next ice age, rush out and conquer the Sahara desert in
preparation for it becoming green once again. If in the meantime
sea levels rise and flood major coastal cities (and the whole
of Florida), MOVE. You'll have to rebuild Disneyworld somewhere
else. Man has survived ice ages, it isn't quite as terrible as tornadoes,
earthquakes, volcanoes, tsunamis or religiously or politically
guided terrorists.

..7.8 x 10^21 molar quantity of oceans
1.8 x 10^19 molar quantity of atmosphere
75.4 heat capcity of water x molar quantity = 5.8x10^23 joules
20.76 heat capacity of air x molar quantity = 3.7 x 10^20 joules
5.7 x10 ^23 joules is the difference

The atmosphere must be 5.7 x 10^23 degrees celcius warmer than the
ocean for them to equalize at the same temperature with the ocean one
degree warmer.
Greanhouse gas theory is deliberate fraud.
Can you discuss this topic twit?
Or must I teach you the rudiments of science before you undeerstand how
much of an idiot you are.
