As the ice retreats

Antarctica looks to us, on our maps, as one roughly circular continent. Ground-penetrating radar, however, shows it as two parts — to the East, the largest part, an elliptical-shaped mass. To the West, the Palmer peninsula and adjacent territories, actually an archipelago. Between the two, land that is actually below sea level. In other words, the ice conceals the fact that what seems to be one land mass is actually a land mass and adjacent islands.

I’m no scientist, but the map above seems to say that the ocean is reclaiming its own, melting the ice that does not sit on land. What does it say to you?

  1. That is exactly what it looks like to me as well. But as you said, I am no scientist. Which is worse? A warming trned or an ice age recurrance. Wouldn’t it be wonderful if life could just always be balanced and perfect. I can’t even keep myself in such order……how could the universe do it?

  2. Rich, doesn’t matter, as I don’t have waterfront property in Antarctica.

    Sherry, I kind of think that an oscillating motion, first this direction, then the opposite, IS a balanced and perfect system.
