The Glacial-Interglacial Cycle is Driven by Orbital Forcing

[EMH]

NBCNews is your source? ... that's sad, really really sad ...

Actually the DATA is the "source," and NBC spun and supported the ridiculous excuses for the FUDGE JOB without questioning them.

INDISPUTABLE TRUTH

We have two and only two measures of atmospheric temps, and BOTH showed NO WARMING for decades despite rising Co2 until being FUDGED in 2005...

 

[EMH]

And that NBC article says that his "highly correlated satellite and balloon data" is crap.

Refute that statement or STFU.

The satellite and balloon data was highly correlated. Both showed "cooler than normal atmospheric temps" the first time your side tried to claim "warmest year ever" in 1998...

Speaking of ignorance ...

How do these orbital parameters change irradiation? ... specifically obliquity ... and show your math please ...

Yeah, we've been through this before ... the math is proof-positive you're a stupid little cockatoo imitating your feminine master ... the moron half of your relationship is stuck being masculine ... BTW, why do gay couples resume using traditional gender rolls, that's just so weird ...

Ignorant mathematics denier ... any decent accountant can make 2 + 2 equal anything we what it to equal ... looks like a $50,000 refundable tax credit to me !!! ...

The explanation is given in the OP. If you actually disagree, you could try explaining why.

The "why" is simple ... obliquity doesn't change distance ... so irradiation remains constant ... go look up the definitions, stupid ...

1,360 W m^-2 ... no, the OP gives an assumption ... one which is demonstrably false ... to stupid to learn? ...

2) Obliquity: These are changes in the angle between the Earth's axis of rotation and our orbital plane. The Earth's obliquity varies between 22.1 and 24.5 degrees over a period of roughly 41,000 years. When the angle increases, the Earth's hemispheres experience warmer summers and colder winters. The effect is latitudinally dependent as higher latitudes (closer to the poles) see larger changes than lower latitudes closer to the Equator. Larger obliquity angles lead to deglaciation. The Earth's obliquity is currently at 23.4 degrees and is decreasing towards the next minimum in about 10,000 years.

Do you believe any of this is incorrect?

That's almost all correct, obliquity's period is all but irregular ... but how does that change average global temperature ... a change between seasons is not general considered changes to climate ... stupid ... if summers are 2ºC warmer and winters are 2ºC cooler, what's the new average? ... right, same as the old average, so no effect on Earth's temperature ...

The question is how does obliquity effect irradiation ... can't you read ... have your mummy help you sound out the words ... my claim is obliquity has no effect on irradiation ... average distance remains 1 A.U. (≈ 93,000,000 miles), as long as that remains the same, irradiation remains the same ...

Why are you denying mathematics? ...

 

[ding]

a change between seasons is not general considered changes to climate

Especially ones that are gradual and slow.

 

[ding]

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?

 

[fncceo]

So, you've chosen to double down on demonstrating your ignorance.

Climate cycle ...

1. Climate fanatic makes a prognosis of doom for Earth based on information he doesn't understand.

2. People question or refute said prognostication

3. Climate fanatic insults their intelligence / gets angry

4. Rinse, Repeat

 

[Robert W]

How about you show us the temperature history for Greenland and North America over that last million years?

That is your assigned job Crick.

 

[ding]

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?

 

[ding]

Larger obliquity angles lead to deglaciation. The

How?

 

[Robert W]

An interglacial is, quite obviously, not an ice-free period. It is simply a warmer portion of an ice age. We are still in the Quaternary ice age and have been for 2.58 million years. That ice should be present in Greenland, North America and Antarctica at any point in the last 3 million years is a surprise to no one. Except you apparently.

Ice grow where conditions allow. At high latitudes. At high altitudes. Look at Mt Washington in New Hampshire. It's one of the coldest places on Earth yet is only 6,800 feet above sea level and south of Minneapolis, Seattle, Paris and London. As for being continent specific, Mt Washington is on the same continent as Furnace Creek, Death Valley, California, the hottest place on the planet.

Or is that all FUDGE?

Did I get you interested in Death Valley, CA the hottest place on earth?

 

[ding]

Ding has claimed that changes in ocean currents are responsible for all climate change for the past 3 million years, which would include the entire Quaternary and it ~30 glacial-interglacial cycles.

Actually my claim begins with the ocean has always established climate by how it distributes heat. The ocean is the largest feature of the planet, is the largest solar energy collector of the planet, contains the majority of heat of the planet and distributes that heat around the planet. Ocean and wind currents exist in large part because the planet is not heated evenly. Climate is determined by land mass distributions and resulting ocean currents and how heat is distributed around the globe and the climate effects it creates. Polar regions are of special interest because these regions receive the least amount of solar energy.

In my next episode of the Cosmos, we will show how the democrat party that can't even control inflation will now magically control the weather if we only surrender enough our money and freedom to them.

Good post, wanna make it great change "democrat" to "liberal" and it would be perfect...I'm a democrat but speak out about "climate change" as being nothing more than a new slush fund for white liberals to use in propping up sagging social economies around the world with U.S. taxpayer money, which btw is the real crime for liberals in their outrage over tax cuts.

So, do you reject the science behind manmade global warming?

I completely reject that it is anything more than a money grab by the left, as there is far more left-wing politics behind "manmade global warming" than science.
