The Glacial-Interglacial Cycle is Driven by Orbital Forcing

Do you think that you know this material better than the sources to which I linked?

I know this material better than you ... and am better qualified to access the quality of your Google AI results ... most of it sucks and the results are based on your personal search habits for the past 12 months ... stupid ... you just puke forth this horseshit like it tastes good or something ...

You offer as fact what is conjecture ... that's profoundly ignorant ... ding doesn't offer as fact what he knows is conjecture, that's generally considered wisjgw ... umm ... wictabr ... er ... well, one hell of a lot smarter than you, though I don't think he'd appreciate the comparison ...

My conjecture is that convection is more efficient at higher temperatures ... and this causes more average cloudiness ... which lowers temperatures ... which reduces clouds allowing more solar energy to reach the surface, raising temperatures, more clouds, etc etc etc ... oscillating back and forth ... no, I have no proof, but I know this is an active area of research ... the reason for the interest is this also explains Arctic amplification ...

Everybody has assholes ... everybody has opinions ... everybody has their pet theory ... if you took calculus in college, then you know the OP is complete bullshit ... Kepler's Laws are a great example for the student, every textbook has sections on them ...

Obliquity doesn't change irradiation ... doesn't change surface temperature ... doesn't change climate ... butch ...
 
Obliquity changes the amount of solar radiation falling on higher latitudes. That will cause glaciation to melt and recede.

Are you teaming up with Ding to contend that the glacial-interglacial cycle is NOT caused by Milankovitch orbital forcing?
So you are persuaded by Milankovitch orbital forcing?
 
Which weather service isn't taxpayer supported? ... did you ever find all that 19th Century satellite data NBCNews has? ...
Your questions are important.
 
Changes in eccentricity are small and so this factor has a small, but non-zero, effect on the Earth's climate.
So slow, gradual and small. How does that cause glacial periods to begin and end?
 
This tends to moderate northern hemisphere (NH) winter and increase the intensity of southern hemisphere (SH) summers. When the angle has rotated 180 degrees, these effects will be reversed.
So slow, gradual, seasonal and no net change to total annual irradiation?

How would this trigger a glacial period and end a glacial period?
 
So you are persuaded by Milankovitch orbital forcing?


Truth is, there is absolutely no evidence at all to back up any of the claims in Milankovich...

Milankovich was cooked up right after homO's "silence" to re-write North American Ice Age from 50 million years to 70k...


 
I know this material better than you
Given that you are challenging a widely held theory without providing an iota of reason, I'd have to disagree.
... and am better qualified to access the quality of your Google AI results
You have not demonstrated such abilities here. You make large numbers of mistakes.
... most of it sucks and the results are based on your personal search habits for the past 12 months ... stupid
I was not logged in to Google. It had no idea who I was when I executed that search. Stupid.
... you just puke forth this horseshit like it tastes good or something ...
You just reject it SOLELY because I put it out. You have no argument. You're just bitter because I've made you look foolish so many times.
You offer as fact what is conjecture ... that's profoundly ignorant
Milankovitch orbital forcing behind the glacial-interglacial cycle is a widely accepted theory, not conjecture.
... ding doesn't offer as fact what he knows is conjecture
Ding offers as fact contentions for which he has no evidence. And he misses the obvious reality about what he thinks himself to be an expert. The oceans are heavily involved in D-O and Heinrich events and, along with plate tectonics, with the actual ice ages the Earth has experienced. But not the glacial-interglacial cycle.
that's generally considered wisjgw ... umm ... wictabr ... er ... well, one hell of a lot smarter than you, though I don't think he'd appreciate the comparison ...
When one of you realizes that the consensus opinions of mainstream science are the most likely explanations for how the universe works, I might consider ceasing to insult your intelligence. Until then, you reap what you sow.
My conjecture is that convection is more efficient at higher temperatures
Efficient at what?
and this causes more average cloudiness ...
Right out of AR2-6.
which lowers temperatures ...
A great deal of research has been done on the effect of clouds on climate but I see you haven't kept up with it.
which reduces clouds allowing more solar energy to reach the surface, raising temperatures, more clouds, etc etc etc ... oscillating back and forth ... no, I have no proof
No one would ask you for proof. They would ask you for evidence. Got any? And if you don't why should anyone - including yourself - think this is the case?
but I know this is an active area of research
Clouds and climate? For decades now. But, as I said, you haven't been keeping up with it.
the reason for the interest is this also explains Arctic amplification ...
It's considered one of several factors.
Everybody has assholes ... everybody has opinions ...
"Opinions are like assholes. Everybody's got one"
everybody has their pet theory ...
But smart people choose theories with the strongest evidentiary support. You don't.
if you took calculus in college, then you know the OP is complete bullshit
I took Calculus I, Calculus II, Calculus III, Differential Equations, Mathematical Physics, Linear Algebra and Advanced Matrix Methods and I know the OP is absolutely correct.
... Kepler's Laws are a great example for the student, every textbook has sections on them ...
The perturbations of the Earth's orbit that cause Milankovitch Cycles is the gravitic attractions primarily of Jupiter and Saturn. Kepler's laws won't help you there.
Obliquity doesn't change irradiation
What you NEED to say here is that obliquity doesn't change the Earth's Total Solar Irradiance and I pointed that out before you did and I have repeated it several times. It DOES change insolation at higher latitudes and that is the means of its climatic effect. I've said that to you repeatedly but you keep ignoring the point.
... doesn't change surface temperature
It certainly does. It changes the contrast between the poles and the equatorial latitudes. You seem to have picked up a mistaken concept. It is not necessary to cool the entire planet to put the Earth into a glacial period; only the higher latitudes where ice will grow.
... doesn't change climate
Yes it does. Ask any scientist.
 
Milankovitch orbital forcing behind the glacial-interglacial cycle is a widely accepted theory


which is sad, pathetic, and "par for the course of the Co2 FRAUD" since mcBULLSHIT is so easily disproven at both poles...
 
Ding offers as fact contentions for which he has no evidence.
Really?
  1. Ocean currents establish climate.
  2. The ocean is the largest collector of solar energy.
  3. The ocean stores the majority of the planet's heat.
  4. The ocean is the largest feature of the planet.
  5. The mass of the ocean is 300 times the mass of the atmosphere.
  6. The ocean contains 1000 times more heat than the ocean.
  7. The ocean heats the atmosphere.
  8. The atmosphere does not heat the ocean.
  9. Physical evidence shows that when ocean currents change, the climate changes.
  10. Physical evidence shows ocean currents are responsible for northern hemisphere glaciation.
  11. If heat circulation gets disrupted from the Atlantic to the Arctic, the planet cools.
  12. Physical evidence shows ocean currents are responsible for northern hemisphere deglaciation.
  13. If heat is being circulated from the Atlantic to the Arctic, the planet warms.
  14. Physical evidence shows ocean currents are responsible for the initiation of the Little Ice Age.
  15. Physical evidence shows ocean currents are responsible for the end of the Little Ice Age.
  16. The current warming trend began 250 years before the industrial revolution.
  17. The geologic record is littered with examples of naturally caused warming and cooling trends.
  18. Empirical climate evidence shows the planet cooled for millions of years with >600 ppm of CO2.
  19. The last interglacial period was 2C warmer with 26ft higher seas and 120ppm less CO2 than today.

So you are persuaded by Milankovitch orbital forcing?
Persuaded? Based on its acceptance among scientists, I also accept it. That's how I do things. I'm not a scientist but I trust the scientific method. I don't believe in insane, irrational conspiracy theories.

Which is probably why you create OP's and then ignore challenging questions.
 
Ocean currents establish climate



Wind is to air what current is to ocean. Just pointing wind and current in different directions does nothing, NOTHING, to change the Earth heat content.

Why this taxpayer funded liar thinks she is helping the cause of the Co2 FRAUD by making this point over and over is laughable.

Ocean currents DO NOT CHANGE EARTH's CLIMATE AT ALL, NO EFFECT ON TOTAL PLANETARY HEAT.
 
Given that you are challenging a widely held theory without providing an iota of reason, I'd have to disagree.

You don't understand the theory ... or you'd explain how obliquity changes irradiance ... and I did provide my reason, obliquity doesn't change distance, and distance is what effects irradiation and temperature ...

You've already admitted you're just repeating what other people tell you to say ... "scientists say so" whimper whimper ... you specifically are unqualified to discuss the OP ...

It's not a scientific theory without the math, stupid ... you're just spewing political vomit ...

e^2 = 1 - ( b^2 / a^2 ) [where e=eccentricity, a=semi-major axis, b=semi-minor axis] {WikiArticle} ... come along Golden Child, what value should we use for "a"? ... let's see if you can Google that ...
 
You don't understand the theory ... or you'd explain how obliquity changes irradiance ...
I have explained personally and quoted and linked to multiple science resource explanations as to how it affects climate. Your claim that I haven't explained it is another lie.
and I did provide my reason, obliquity doesn't change distance, and distance is what effects irradiation and temperature ...
Why, then, is it colder in the winter and warmer in the summer, where it is, respectively, closer and further away from the sun? God you really need to engage your brain before you start typing... If you've got one to engage.
You've already admitted you're just repeating what other people tell you to say ... "scientists say so" you specifically are unqualified to discuss the OP ...
Who are you quoting because I never said those words. Another lie. And I'd say I'm significantly more qualified to have posted and discuss the OP than are you. Fortunately for you, there are no rules along those lines on USMB. If a brain dead monkey wants to talk about String Theory, he's free to do so .
It's not a scientific theory without the math, stupid ... you're just spewing political vomit ...
You've seen my links. Which ones do you believe were political?
e^2 = 1 - ( b^2 / a^2 ) [where e=eccentricity, a=semi-major axis, b=semi-minor axis] {WikiArticle} ... come along Golden Child, what value should we use for "a"? ... let's see if you can Google that ...
For the Earth, they vary. And they vary due to the gravitic influences of other bodies, primarily Jupiter and Saturn. Why don't you give us the equation to calculate what those axes will be in, say, a million years? Because Milankovitch did.

You mean besides distributing heat :rolleyes:
 
I have explained personally and quoted and linked to multiple science resource explanations as to how it affects climate.
No, you haven't. You have waved your arms and avoided addressing tough questions.
 
Persuaded? Based on its acceptance among scientists, I also accept it. That's how I do things. I'm not a scientist but I trust the scientific method. I don't believe in insane, irrational conspiracy theories.
I understand you are like that spaceman arriving on Earth to save this planet. Keep it up for your joy.

No you haven't ... you're just going to lie now ...

But I get it ... you can copy/paste from Google ... but you're too stupid to copy/paste yourself ... [hand wave] ... the OP is falsified ...

I posted my opinions of ding's ideas in the thread he posted them ... too stupid to find that? ... this thread is complete nonsense from the beginning ...
