The debate over hydraulic fracturing has recently focused on the rise in seismicity throughout the primarily stable interior of the United States. These intraplate regions, though not unfamiliar with earthquakes, have been experiencing an increased amount of seismic activity in the last decade. This unusual increase is likely to be caused in part by wastewater disposal practices related to natural gas production. With such a sensitive issue it is important to keep the facts in perspective.

The idea that the Arctic is changing is not breaking news. Sea-ice extent has been declining by 12 percent per decade since 1979, and the ice is thinning too. Because of this, new shipping routes are becoming accessible during the summer months, and the Arctic is beginning to attract parties interested in resource exploration, scientific research and tourism. Therefore, a more accessible Arctic not only means environmental changes, but also changes in our economy and our national security.

Tornadoes are notoriously difficult to forecast, with often deadly results: In 2011, tornadoes in the U.S. killed more than 550 people, a higher death toll than in the past 10 years combined. Now a new study on short-term climate trends offers a fresh approach to tornado forecasting that may give people in tornado-prone regions more warning that twisters may soon be descending.

Beautiful views and exotic thrills draw millions of tourists to volcanic sites each year. Previously frequented by smaller numbers of experienced hikers and trained tour guides, today's volcanic sites are plagued by throngs of novice hikers, who are often ill-prepared and uneducated about the risks of volcano geotourism. These groups of vacation-goers often display a lackadaisical attitude about safety that can put their lives at risk.

Since last July, NASA's Dawn spacecraft has been orbiting the asteroid Vesta, and capturing images and other data that are providing surprising results to the delight and amazement of researchers. Dawn's mission is to help reveal the processes and conditions that marked the first few million years - the dawn - of the solar system; and the information the spacecraft has collected about Vesta is changing the way scientists think about the formation of our early universe.
