Puddled meltwater very likely primed this ancient edge of the Antarctic's Larsen Ice Shelf to rapidly disintegrate over just several weeks. This view of the splintered mix of frozen bergs is from a Feb. 21, 2002, satellite image.
An expert panel at the National Academy of Sciences is calling for an early warning system to alert us to abrupt and potentially catastrophic events triggered by climate change.
The committee says science can anticipate some major changes to the Earth that could affect everything from agriculture to sea level. But we aren't doing enough to look for those changes and anticipate their impacts.

Once upon a time, you could crack open a radio, a telephone, a lawnmower, even a car, take it apart and figure out how it worked. No more. Pretty much everything we use these days comes with computer chips, which you can't really take apart. (I mean, you can, but all you'll find inside are a bunch of 1's and 0's with no obvious logic.) So car mechanics can snap a new chip into an engine, wait till it whirs and watch the gears come to life, but do they know what's going on in there? For most of us, chips are "black boxes." They work, but we don't know why.
Workers process applications for Oregon's health exchange program. The state paid tech giant Oracle to build its online exchange, but with the site still not functional, people shopping for insurance have been forced to apply on paper.
Oregon has spent more than $40 million to build its own online health care exchange. It gave that money to a Silicon Valley titan, Oracle, but the result has been a disaster of missed deadlines, a nonworking website and a state forced to process thousands of insurance applications on paper.
Some Oregon officials were sounding alarms about the tech company's work on the state's online health care exchange as early as last spring. Oracle was behind schedule and, worse, didn't seem able to offer an estimate of what it would take to get the state's online exchange up and running.
A former Amazon executive who helped Jeff Bezos turn shopping into a digital experience has set out to end illiteracy. David Risher is now the head of Worldreader, a nonprofit organization that brings e-books to kids in developing countries through Kindles and cellphones.
Risher was traveling around the world with his family when he got the idea for Worldreader. They were doing volunteer work at an orphanage in Ecuador when he saw a building with a big padlock on the door. He asked a woman who worked there what was inside, and she said, "It's the library."
