Earth Gains A Record Amount Of Sea Ice In 2013

and remember how horrible it was?

almost no post was ever deleted, insults were encouraged if in shakesperean form, and all the rawn pawl spam never got merged because we were all just too damn lazy.

those were horrible times.

I think you would be the better mod. More even handed evil. :)

It is .98 day per degree of orbit times the major/minor axis wobble period summed with the polar axis precession/ 360. On top of that is a 3rd wobble, the planar wobble of the orbit like a old 78 rpm record left in the sun, remember those? But, it is double period and mostly averages....mostly. That accounts for the long term graph of, NOT THE SHIFT OF THE SEASONS, it is the proportional length changing.

21000 years / 360 degrees = degree of summed precession per year x .98, to cook out the leap year or 57.2 years for 1 DAY. earlier for the NON-CALENDAR SHIFT. We are talking about the climate change that happens constantly within a lifetime.

70 days, I found last night is if you don't sum the first two wobbles.

thank you for the math
But can you please point me to somewhere that agrees that you need to do it?

I have tried googling many variations of calender accuracy, 57.2 and other factors and come up with nothing

If it is a day shift then it wouldn't be climate change it would be a slight season shift

Were atm seeing spring arrive earlier than just a day's worth

I'm not sure why you added the marine part in what part are you saying is the deeper science?

Mean 70 years there of course, but can't edit today. Need to add more than 10 characters. Weird.

And Ginga, do you just play at it? The math is right there. And how many times can you ignore what is the crux?
NOT CALENDAR.

What do mean, NEED IT? Why do we need to understand precession, and lifetime period climate change?

No one needs it. If the mental head is in the sand, why need facts?

nope.

you couldnt rustle my jimmies with a TEAM of guys.

and the arctic sea still isnt even Partly enclosed.

you so silly.

also, as axial precession cycles about once every ~26000 years, and a year is ~365 days, so 26000 / 365 = the precession advances by one "day" every ~71.2 years.

but then im noted for having less than stellar Maths.

it sounds about right to me though, in a Ballpark kinda way.

i especially like how you both came up with different numbers but they seem right to you

I congratulate you for having found love, even briefly.

I said I calculated it and I listed the simple math. It isn't magic, and it isn't even orbital calculus. It is the reality of the System. It is the pump of the 2ond Law of Thermodynamics. It is why we must add leap year. It is the Climate Change engine.

And it is such a change, a full day in the energy balance, we observe the change within a lifetime. That's the point.

I'm not making a contention. I am stating facts and you seem to be barely reading it.

oh i know that law

it states that if you cannot show your not talking out of your arse then allude to a real scientific law and change your 57.2 years to 4 years to fit...

wouldnt angular momentum be a more fitting law?

The tropical year, also known as the solar year, is about 365.242199 days, but varies from year to year because of the influence of other planets. It is the time that the Earth takes to circle once around the sun.

~ me.


is my math in error? if so, explain.

the axial precession was the issue at hand, via the milankovic cycles.

if you propose a different solution to the precession question, feel free to espouse it.
 
And if we use 21,000 as the time for the two systems to resolve 1 period, as I have referenced, you get the 57 years.

1- axis of earth
2-major/minor axis of earth orbit

the milankovic cycles specify 26000 years as the period for a full cycle, nowhere have i seen 21000 years as the period.

period.

you got a link to an explanation to why the 26000 year cycle gets "rounded down" to 21000?
