Red Planet Warming

High-resolution images snapped by NASA's Mars Global Surveyor show that levels of frozen water and carbon dioxide at the Red Planet's poles have dwindled dramatically — by more than 10 feet — over a single Martian year (equivalent to 687 days or about two Earth years). Michael Caplinger of San Diego's Malin Space Science Systems points out that if the warming were to continue at the same rate (that's a big "if"), Mars could become a nearly inhabitable place for people within 5,000 years or so. "Rather than wearing a spacesuit, you could get away with wearing just an oxygen mask and a thick parka," said Caplinger, who co-authored a study about the observations in this week's issue of Science. "It would be like standing on top of Everest."
