But just in case you wanted a second opinion, a new study out of Princeton University takes a look at a decade's worth of satellite data. Their results, published in Earth and Planetary Science Letters, show that not only is Antarctica melting, it's melting faster than ever before. Unlike other studies that looked at the volume of ice lost, this study used data relating to the mass of the ice--the difference the researchers say between measuring weight loss by looking in a mirror versus using a scale. While looking in a mirror (or the volume of ice) can give you some idea of what's going on, it's sometimes deceptive. Snow compacting into ice leads to a reduction in volume, but only ice melting into water or breaking off the continent registers as a change in mass.
