Us older folks should lead protests about the amount of oxygen in the atmosphere causing us to age faster! Just think, if we could get rid of that awful stuff completely, none of us would age another day!
I read something interesting in this mornings newspaper.... "scientists have found a volcano under Antarctica,the last eruption about 2500 yrs ago, they could tell by ashes in the ice ,there was so much ash that previous thoughts about being bedroock has now been determined to be ashes, and real bedrock is lots lower...and they think this volcano is heating up, there by melting the Antarctic ice!" how `bout that Al Gore!?
It's really going to be interesting to see what is under all that ice.... Funny thing is that the Russians are really getting 'posessive' with their portion of the 'undercap'. To the point of saying they will defend it with nukes....

Yes. Are you familiar with the scenario that is predicted when one cap melts and the other doesn't? It relates to the 2012 issues.... Polar shift effects both poles and also the rest of the world depending on the shift. It could move the Artic(crust) to the area we now call North America.
no, not familiar...but that would make the "Global Warming" in Canade something?! and it would make Texas feel like Sweden...
but ...this news shows theres more to "nature" than so called "scientists" are aware of....volcanoes have a LOT to do with our temperature changes and so does the sun! lot more than Hummers...even though it would be nice to 'clean up' the planet...but doubt it has any major effect of temperatures ,but it WOULD be nicer surroundings for humans...
There are records that show that the poles were not always where they are now. The scientists can only guess why they moved. One popular theory is that the ice caps got so big they 'wobbled' and shifted. Another popular theory is that one ice cap melted and the other didn't which shifted the crust. This theory was scoffed at because what could melt and ice cap? The countered with the theory that a meteor hit an ice cap melting it. They didn't know about the vulcano....
here`s the article, it was rewritten for the "Houston Comical", but was originally in the NY times...
Jan. 21, 2008, 12:16AM Scientists implicate volcano in melting of Antarctic ice
By KENNETH CHANGE New York Times
Here is another factor that might be contributing to the thinning of some of Antarctica's glaciers: volcanoes.
In an article published Sunday on the Web site of the journal Nature Geoscience, Hugh F.J. Corr and David G. Vaughan of the British Antarctic Survey report the identification of a layer of volcanic ash and glass shards frozen within an ice sheet in West Antarctica.
For Antarctica, "this is the first time we have seen a volcano beneath the ice sheet punch a hole through the ice sheet," Vaughan said.
Heat from a volcano could be contributing to the thinning and speeding up of the Pine Island Glacier, which passes nearby, but Vaughan doubted that it could be affecting other glaciers in West Antarctica, which have also thinned in recent years. Most glaciologists, including Vaughan, say that warmer ocean water is the primary cause.
Volcanically, Antarctica is a fairly quiet place. But sometime around 325 B.C., the researchers said, a hidden and still-active volcano erupted, puncturing several hundred yards of ice above it. Ash and shards from the volcano carried through the air and settled onto the surrounding landscape. That layer is now out of sight, hidden beneath the snows that fell over the subsequent 23 centuries.
Although out of sight, the layer showed up clearly in airborne radar surveys conducted over the region in 2004 and 2005 by American and British scientists. The reflected radio waves, over an elliptical area about 110 miles wide, were so strong that earlier radar surveys had mistakenly identified it as bedrock. Better radar techniques now can detect a second echo from the actual bedrock farther down.
Scientists knew that an eruption occurred around 325 B.C., plus or minus a few years, but did not know where the eruption occurred. "We're fairly confident this is the same eruption," Vaughan said.
"It's probably within Alexander the Great's lifetime, but not more precise than that," Vaughan said.
One thing that can rest your mind at ease is that there's no evidense that there was any polar shift around the time they say the last eruption was... But if you add in the 2012 scenario, that could make a difference.
Im` not sure the 'shift' would have impact or not on an eruption...if its buiilding up steam, its going to erupt where the cracks are or path of least restriction...no matter if theres a mile of ice over it... but during the 'build up' time, I`msure the earth around it would heat up and melt the ice...possibly thats the difference between melting in the south and building back up ice in the north? with the +_40 yr cycling of the solar input....theres lots more to it than a few "Hummers".....
Magnetic shifts are mild. Mostly just electronics effected. The polar shift is a lot more dramatic. It would basically move the crust in relationship to the sun. When all the planets line up in 2012 there could be a slight difference in gravitational pull. Which isn't predicted to do much with the present day Earth crust configuration. But if there was an inbalance in the crust, then the theories abound that there will be a shift. If the vulcano erupts, melts just one ice cap, the plants all line up right at that time(2012) there may be enough pull to cause the polar shift. Scientists can prove polar crust shifts in the past but they didn't know why they happened.
One thing that is attributed to a past polar shift is the Bermuda Triangle. It's believed, by some scientists, that one pole was there.... There is a corresponding place on the opposite side of the Earth from that. There is a measureable magnetic anomaly there. And also a slight change in gravity there.
The one magnetic shift that isn't mild is due to happen, the magnetic North and South switch. Not in our lifetime but it's coming.
I've seen this 'modeled' in some experiments. Mostly just electronics were effected. They can actually measure that the switch is already happening. Very slowly.
