A funny little man writes "The popular open source privacy tool, TrueCrypt, has just received a major update. The most exciting new feature provides the ability to encrypt an entire drive, prompting the user for a password during boot up; this makes TrueCrypt the perfect tool for non-technical laptop users (the kind who are likely to lose all of that sensitive customer data). The Linux version receives a GUI and independence from the kernel internals, and a Mac version is at last available too."

Now NASA scientists using satellite data have published a paper in 'Science' demonstrating increased melting around the margins (mostly) of the Antarctic ice sheet. This is potentially much more serious, as the margins act as barriers, preventing the much larger land-borne ice-sheets sliding off the continent into the sea — causing a catastrophic 4-6m rise in sea-levels.
I was just wondering that, too. TFA specifically says "they say these lakes lie some 2,300 feet below compressed snow and ice, too deep for environmental temperature to reach," so how the heck does Global Warming affect this? It it was global warming, the ice on TOP would melt - not the ice on BOTTOM! I would more likely suspect it's due to friction of the sliding ice or heat generated from within the Earth (such as volcanic activity).
