>>Antarctic Glaciers Going To Sea At Faster Rate<<

Well then we ought to use American ingenuity to put masts on them and sail the damn things.

[CodeMasterPhilzar]

A while back (few months) I read somewhere, a C02 something or other website, an article that was refuting the idea that GW was causing Antarctica to lose its ice. Their conclusion after satellite radar surveys etc. was that Antarctica was experiencing a net gain of 29 Giga tons of ice per year. This would seem to be in line with that. If you pile up more and more ice on top, it is going to slide down to the sea at an ever faster rate...

“Is that like farting under the covers?”

I did that once. When the “global warming escaped into the atmosphere, my wife stuck her head under the covers.
Boy, did I get the blunt end of the “global warming’ stick that night.

It’s not Global Warming,
it’s Ocean Warming

Unrecognized Underwater Volcanic Activity
13 Jul 07 - Transform faults are not developing or behaving as
theories of plate tectonics say they should. The faults are often
segmented and show signs of recent or ongoing volcanism.

That's a big thick glacier. I wonder if it contains millions of cubic miles of liquefied water behind, and under, the ice?

There's a newer theory bout the Grand Canyon gorge that postulates a similarly large glacier in Canada burst like a water balloon during its recession.....blasting the entire central area of North America with a land-tsunami....and the canyon it a vestige of the flood. Other evidence includes hills characteristic of water flow across the plains...like the ripples of sand on a wave-washed beach...on steroids.

If that's a similar case in Antarctica, the planet could be in for a major soaking wave sometime soon, as the ice liquefies in the interior, and the ice-dam breaks.

Swoosh! [Bush's fault.]

...On average, Antarctica is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Since there is little precipitation, except at the coasts, the interior of the continent is the largest desert in the world...

How confusing.

We need an expert like Al Gore to sort all this out for us.

[GOPJ]

Scott's research revealed evidence of a volcano that erupted through the ice about 2,000 years ago. The whole region could be volcanically active and could possibly be releasing geothermal heat to melt the base of the ice and help its slide towards the sea.

The problem is the global warming people will see the sea level rise and hit us with it...

Thanks for the links — I think ;^)

Actually, with more ice than ever and a thicker than ever ice cap, you expect them to speed up because there is more weight pressing down. But to imagine this is going to move sea levels is utter nonsense. A millimeter, nobody will care. Go down to the sea shore and try to measure the water height with millimeter accuracy. (lol)

[JasonC]

Actually, it is quite simple at the practical level. None of it will ever change enough to matter, for anything, in the lifetime of anyone here. All the talk about it is utterly futile. By all means, investigate the details for the sake of pure knowledge, for its own sake. But pretending anything practical turns on it is utter horsefeathers from start to finish.

[mowowie]

cracks me up....

[TheThinker]

Wait, if Antartica is mainly ice, then much of it is just floating. Whether it melts or not is of no consequence. Drop an ice cube into your favorite drink and it has the same displacement as if it melts.

[mowowie]

That’s what i’ve always thought.
But that makes sense though...

Geologists Say Global Warming Expected to Cause Many New Seismic Events

Well, it has happened in the past...remember that this isn't the first warming we've experienced...in fact, here in North America, the crust hasn't totally rebounded from the last glacial coverage.

[Gondring]

Wasn't that when we were warned about global cooling and told glaciers would overtake the earth?

No...Not any place I know of!

[fight_truth_decay]

The planet has a fever!” Thermal activity under the glacier? Is that like farting under the covers?

Great idea for a project for the kid's science exhibit/ competition or a great line for Jay Leno. In fact....Thanks

Actually, it is quite simple at the practical level. None of it will ever change enough to matter, for anything, in the lifetime of anyone here.

Actually, that's not true. The climate change we've seen to date has been significant. However, the question of whether it's man-made or not is not going to be confirmed anytime soon.

All the talk about it is utterly futile. By all means, investigate the details for the sake of pure knowledge, for its own sake. But pretending anything practical turns on it is utter horsefeathers from start to finish.

Again, not really. If the climate change we've observed is purely natural, then it will mean that the rational managed response to it will be different from if it's not natural. And even if we can't quantify it, we might be able to get qualitative answers that can tell us whether cutting emissions is most efficient--or whether there are other answers, such as counter-revolving sunscreens, or perhaps not doing anything at all.
