Time lapse videos of change on Earth

A blog at the Wired magazine website has a series of interesting changes in the earth over the past decade, sometimes for good but usually for, well, not good.

For example, take a look at a time lapse of Lake Powell in Utah and the effects of a drought on the lake over the past ten years:

Southern Utah’s Lake Powell was once teeming with boaters, fishers and vacationers. But from 2000 to 2005 its water level dropped from 20 million to 8 million acre-feet, due to severe drought. Water levels have rebounded a bit, but are expected to plummet to levels even lower than those of 2005 during the next serious drought.
