"It's just physics."

That's the mantra coming from Richard Alley, as he lightly bangs the table in emphasis, while taking a break from the 17th annual West Antarctic Ice Sheet Workshop, a conference held outside of State College, home to Pennsylvania State College.

The meeting has brought together most of the polar scientists with interests in the West Antarctic, home to a marine-based ice sheet that has become a cause of concern as the world warms up. Complete disintegration could raise sea level up to 6 meters. On the timescale of the next century, it's likely to be a major contributor in the one-meter-plus global rise many are predicting.
