Yosemite fire still burning out of control

The Yosemite Rim fire is still burning, with over 4,000 firefighters dispatched to fight the fire. Recent reports are that the blaze is now 20 percent contained (up from 7 percent yesterday) but this one is going to take a while to rein in. It's currently one of the 20 largest fires in California history, so big that it has its own weather system. And it could be a sign of things to come.
