If someone detonated a megaton range weapon over the land ice in Antarctica, would sea levels rise much? |
|
It would put a dent in it, but not enough to raise sea levels. Drop in the bucket as far as the ocean's volume. Unless of course it's a Haliburton weapon, in which case not only will it raise sea levels 300 feet, it'll also create nuclear winter––but only if Dick Cheney ordered it. ETA: And for a sense of scale: the explosion of Mt St Helens weighed in at about 25 Mt. |

No.
Provided that the dry land does not sink very much, or that we do not lose it to subduction*, the sea level will never rise more than a few feet. *Subduction is where tectonic plates slide under, or slide over other tectonic plates. Remember, almost 95% of all climate change "facts" are pure bullshit...at best. Quoted:

So, either it was much warmer a few hundred years ago, or that map was made by aliens a long, long time ago. |

well, since the bomb wouldn't do it....
What about all the hot fucking air in DC along with Al Fuckin' Gore.... I bet that BS would melt the entire Ice Cap |

Might not raise sea levels, but mushroom clouds look cool so lets do it

If someone just has to get their bomb off, I would appreciate they do it in a place with less worth like Haiti or certain parts of Africa, possibly France,..when Obama's visiting. |

Nope........not enough thermal energy to make much difference. |

Lost continent. We should start arfcom land there,USA 2.0. It would only be for the hardcore. But it would be the freest most industrious badass place ever. As long as you like beans in Chili |

Only if the nuclear device was delivered on a treadmill. Then it would never get airborne! |
|
The ice would be instantly vaporized into various isotopes and float off into space. Water from the sea would then be converted into snow to fill in the hole that the vaporized water left and the sea levels would actually decrease.

In the grand scheme of things, our most powerful nuclear bombs are really, really tiny. Every single nuclear bomb mankind has ever made wouldn’t be enough to put a dent in the Antarctic ice sheet.

I would think that the ice would just re-freeze. Even the largest nukes aren't going to have much of an effect on a continent-size ice mass. Ex: Full-yield Tsar Bomba at 100 megatons releases approximately 4 X 10^17 Joules of energy. That's enough to melt about 6 X 10^14 grams of ice at Antarctica's average -60 Fahrenheit temperature. That's 600 million metric tons of water, or six hundred billion liters, or a hundred and sixty billion gallons. Spreading out over a continent at ninety degrees below freezing, that's almost nothing. |

Jeebus, for the last time; melting ice caps do NOT cause the seas to rise...
Same thing goes for ice in a tea glass. When the ice cubes melt does the glass overflow? NO! Please, go take an intro to Geology class, people. |

If that ice got melted and ran into the oceans then the levels would rise. |

They still believe that crap over there. Those 12,000 or so posts haven't done anything to thicken your skin, little girl. Granted, a lot of Antarctica and even Greenland have the landforms (ice cap bottoms) below sea level, but they still have an awful lot of ice directly supported directly by continental mass directly. Arctic Sea ice, and the periphery Antarctic sheets are of course floating, and melting them will not raise sea levels. |

If true, it shoots down the theory that Antarctica has been covered in ice for millions of years. Some will not have their world view challenged, their brains are not flexible enough to accept anything they have not been told. So who mapped Queen Maud Land maybe 6000 years ago on a gazelle skin? |

I've read a bit on the map; it tends to be discussed on "mystical documents" websites a lot. It's pretty easy to determine the age of an ice sheet simply by coring it. Those sheets are more than 2400 years old. And yes, they move laterally, but unless you've got some mechanism for melting a shit ton of ice, pushing the edge of the ice back hundreds of miles, and then growing the glacier back, all in a geological instant, I'm going to go with "some other explanation for the map." Some will do anything to challenge the accepted world view with no proof. As stated here constantly, extraordinary claims require extraordinary evidence. |

Wouldn't the water just fill in the space where the ice was? If the ice is sitting in an indention in the ground it could make a lake but if it's just sitting on top of the ground above sea level and there's nothing to impede it's path it'll run into the ocean. |

I would assume that the blast would make a crater in the ice, and that a good portion of the melted/vaporized water would condense and accumulate into said crater and refreeze fairly quickly at those temps. What wouldn't stay within the crater area would probably condense and freeze in the atmosphere before it got too far away and would probably fall as snow on the continent somewhere, raising the ice level in the surrounding area before contributing much to the ocean. This is, of course, assuming that the event happened near the center of the continent. If it was closer to the coast, it's anyone's guess. |
