More water is moving through the Greenland ice sheet system and there appears to be a link between more abundant melt water and the observed increase in ice flow acceleration.

This paper is extremely important, because it shows the rapid response of this ice sheet to climate warming.

We don't know how much more.

It's unbelievable what it does. Water plant operators used to operate the plant. You used to have to turn things on and off. Now you basically watch to make sure the computer is doing what it's supposed to.

It's a better commuting bike. It's got everything for the urban environment: fenders to keep water from your clothes, a suspension T-post, suspension fork for comfort, a back-rack, integrated urban lock, front and rear lights, and 24 gears. And the handlebars are raised to sit you upright, which means you lose some leverage, but you see traffic better and it gives you exercise without horrible pain.
