Magnetic field reversal? Isn't that what caused the flooding in "Waterworld"? (maybe the other person in America who saw that movie is a FReeper).

Delighted *ping* for the dating.

The earth is only 6,000 years old. Obviously this study was funded by Moscow. I want some real news!

Magnetic field reversal?That's the Y2K for compass makers.

Interesting post. The last time I read a report on ice core analysis, it was reported that increased levels of co2 corresponded with thicker ice layers, contradicting the global warming hysterics.

The earth is only 6,000 years old. Yeah, sure. And the world will come to an end on Dec 31, 1999.

It did come to an end. You round earthers are always spewing your nonsense.

Ice core PING. [This ping list is for the evolution side of evolution threads, and sometimes for other science topics. FReepmail me to be added or dropped.]

There have been a lot of "oldest ever" threads lately. This one is the newest ever.

This notation appears on the graphic and in the text:
A period between ice ages known as Stage 11, which occurred about 450,000 years ago, is of particular interest because the Earth's orbit at that time is believed to have been very similar to its orbit today.
Would you happen to know how the similarity of Earth's present orbit to a prior period's orbit is determined?

...while high carbon dioxide and methane levels indicate periods of global warming. Gosh. You mean there have been periods of global warming prior to now? Must have been those previous civilizations and their nasty, dirty industries.

Would you happen to know how the similarity of Earth's present orbit to a prior period's orbit is determined? Orbits are mathematically predictable ... in both directions. Using a bit of calculus, astronomers can pretty much determine the configuration of any orbit for any time period. I've got a cheapy astronomy program on my machine at home that generates night skies for any date and time over the past several thousand years and into the future several thousand years.

You know, I've got one of those too, and it didn't even occur to me. I tend to think of those as star mappers or, as you described yours -- it "generates night skies." Of course, it would have to calculate Earth's position to do that.
Duh!

AlGore invented ice about 750,000 years ago.

Weren't some naysayers complaining this core shouldn't be exposed to our air as it might release all sorts of ancient viruses? Yikes, get the plastic sheeting and duct tape ready.

A period between ice ages known as Stage 11, which occurred about 450,000 years ago, is of particular interest because the Earth's orbit at that time is believed to have been very similar to its orbit today. It could give us our best picture of what today's climate would be like without man-made pollution or global warming, says Eric Wolff of the British Antarctic Survey. What a crock!

really cool.
