Comet Dust Found In Antarctica

sciencehabit writes: Researchers have discovered comet dust preserved in the ice and snow of Antarctica, the first time such particles have been found on Earth's surface (abstract). The discovery unlocks a promising new source of this material. The oldest astronomical particles available for study, comet dust can offer clues about how our solar system formed.

    After most of that ice melts, thanks to global warming, other interesting discoveries are to be made.

      "Transparent" is a shit show that trades on every stereotype going. A man in drag is NOT a transsexual.

      No, that's just a silly movie. The discoveries of this university research project in the 1930s are much more disturbing: http://en.wikisource.org/wiki/...

      In the mathematical models I've seen, ice in Antartica growing is in fact a sign of global warming. Thinking that warming is going to be uniform is hopelessly naive on a world with the complex ocean and atmospheric phenomena we have.

      Antarctic SEA ice is growing.. Antarctic LAND ice is decreasing.

      If I had to venture a guess, land ice melting into the sea lowers the salt levels of the surrounding waters making a higher freezing temp and thus increased sea ice.

    of a sci-fi movie. take the comet dust inside, where it's warm, and things start to happen.
