  • Dwindling Arctic Ice
    • http://earthobservatory.nasa.gov/Study/ArcticIce
    Since the 1970s, Arctic sea ice has been melting at the rate of 9 percent per decade. NASA researcher Josefino Comiso points to an accelerating warming trend as a primary cause and discusses how global climate change may be influencing the shrinking Arctic ice cap.

  • Denali's Fault (DAAC Study)
    • http://earthobservatory.nasa.gov/Study/denali/
    During the afternoon of November 3, 2002, the water in Seattle’s Lake Union suddenly began sloshing hard enough to knock houseboats off their moorings. Water in pools, ponds, and bayous as far away as Texas and Louisiana splashed for nearly half an hour. The cause? Alaska’s Denali Fault was on the move, jostling the state with a magnitude 7.9 earthquake.
