The extra mass on the planet caused by all these SUVs being manufactured is making the Earth heavier, so the sun is pulling it in closer.

My God! Think about all the things we make and how much they weigh. What if it gets the earth off balance, like a washing machine, if you pile too much on one side? Have you thought of that? We could spin off into the Kuiper belt for all we know.
No, and for the same reason that the peak of Sun exposure in the northern hemisphere is June 22, but the peak of the summer heat is later, in August and September. Since the perihelion is now in January, the model suggests we may be at the start of a long cooling season that may start a new ice age in the next few thousand years.
Note that it was 12,000 years ago that the peak was in June, and 12,000 years ago that the earth started warming up from the last ice age.
So we are going into an ice age according to your theory slowhandluke. Dang. I knew property in Florida would remain a good investment.
: )
I suspect the there’s more variability within the Sun than such wide and aperiodic shifts in Earth’s orbit.
Wow! We globally wobble and warm on the “to” and cool on the “fro”....
Al Gore must be scratching his head wildly...
No update needed. You're one of an innumerable many, probably misled by bad information present in the blogosphere, which confused the global numbers with the U.S. numbers. 1998 was, by far, the warmest year globally in the temperature record. The NASA changes affected the U.S. temperature record and barely nudged the global temperature record. Point #4 is correct because it is about the global temperature record.
Not to start something, but do you, in the end, propose that global warming is man-made?
See this post: http://www.freerepublic.com/focus/f-news/1886643/posts?page=57#57
and realize that it's impossible for me or anyone to refute the basic physics of Earth's radiative balance.
In 1997, Nature magazine, science editor Roger Highfield reported that MIT’s sampling of sediments near Bermuda suggest that the last warm inter-glacial period stretched from about 118,000 to 127,000 years ago. He noted that the author, Dr. Jess Adkins of MIT pointed out the present warem period - “The holocene” has been stable for around 9,000 years.
The article, just 10 years ago was an MIT study that we were on the brink of a new ice age.
I've always suspected the sun varies, but my Timex doesn't.
Not in the Northern Hemisphere. Summer time is when the earth is farthest from the sun, while in Winter, we are closest to the sun. It's the tilt of the planet that causes us to be warm in the summer and cold in the winter.
However, I do agree that global warming is not man-made.
I think it's a little more complicated than that. It sounds like there's a timing issue.
The seasons are caused by the 23.5 degree tilt of the Earth's axis. Summer happens when a pole (north or south) is pointed sunward.
As the article states, Earth's perihelion regresses with a period of about 23,000 years. There are times when summer and perihelion line up, and there are times when they do not.
When summer (at either pole) coincides with perihelion, there's a few percentage points difference in insolation, as compared to when perihelion does not coincide with it.
It makes sense .... and it's good to have some empirical data to support the theory.
What the article doesn't mention, is where we are now in the cycle. You'd think they'd mention that....
Oh NO! We’re not in the spin cycle, are we?!? We’ll die!
Wow! We globally wobble and warm on the “to” and cool on the “fro”....
Al Gore must be scratching his head wildly...

He’s thinking, “how can this be used to justify a larger government?”
I think the answer is obvious. It will be hard to feed so many billions of people during an ice age. This requires immediate planning to create food factories that can operate in extraordinarily cold temperatures. We only have a thousand years, maybe two, three, four or five, to prepare.
We're not.
Ice Age. See the end of the "Glacials and interglacials" section, and find reference 5 if you want the full story.
The concentrated weight of 20 million aliens who’ve moved up north is causing the Earth’s tilt to be greater than normal - we need to deport about 19.5 million to balance our wobble by redistributing or more centrally locating the weight.
I fight global warming by running my SUV all day with the air conditioner on and the windows open.
“We’re not.”
I know.
Before anything else, kudos to you Cogitator for continuously raising the level of debate on AGW.
But I have to say: we should clarify how far back the temperature record we're talking about goes. 1998 was ~ 3 degrees Centigrade cooler than the warmest parts of the Mediaeval Warm Period, and five degrees cooler than when Dinosaurs roamed the Earth.
