Worries about Yellowstone grow

Yellowstone Volcano Grows as Geysers Reawaken

Forces brewing deep beneath Yellowstone National Park could be making one of the largest volcanoes on Earth even bigger, a new study reveals.

In the past decade, part of the volcano has risen nearly five inches, most likely due to a backup of flowing molten rock miles below the planet's crust.

While the rise may not be noticeable to the casual hiker, the activity may have cracked the crust in the park's famous Norris Geyser Basin (NGB), leading to the formation of new fumaroles-holes that vent smoke and gas-and the reawakening of some of the area's geysers, including Steamboat, the largest geyser in the world.

Yellowstone last erupted about 640,000 years ago, spewing 240 cubic miles of material. Despite the newly discovered activity, researchers don't expect it to erupt any time soon. Eventually, however, it could explode again as a super-volcano that would destroy life for hundreds of miles around and coat the entire country in ash.

Antarctica Losing Ice, Contrary to Expectations

Joining the growing list of places on this planet that are melting, Antarctica is losing some 36 cubic miles of ice every year, scientists said today.

For comparison, Los Angeles consumes roughly 1 cubic mile of fresh water a year.

The south polar region holds 90 percent of Earth's ice and 70 percent of the total fresh water on the planet, so any significant pace of melting there is important and could contribute to an already rising sea.

"This is the first study to indicate the total mass balance of the Antarctic ice sheet is in significant decline," said Isabella Velicogna of the University of Colorado at Boulder.
