Well, Duh!
Last week, scientists let us know that the arctic ice cap (sea ice) is melting, thus "proving" that global warming is alive and well and out to destroy the planet (thanks to us and the evil SUV, of course). Well, I just heard an interesting interview with a researcher that gave me a true "well, duh!" moment.
Robert Felix pointed out that the sea ice is already floating. "So what?" you ask. Well, think about it. When you have a glass of ice water, and the ice melts, does the glass overflow? Do you suddenly have more water (a higher mass) than when you started? Of course not. The volume remains the constant, even though the state changes.
Then again, Mr. Felix thinks that we're on the verge of an ice age (and no, it's not our fault... it's a cycle...). And I think I'm ok with that. I miss snow down here.
