Mars Emerging from Ice Age, Data Suggest

Scientists have suspected in recent years that Mars might be undergoing some sort of global warming. New data points to the possibility it is emerging from an ice age. NASA’s Mars Odyssey orbiter has been surveying the planet for nearly a full Martian year now, and it has spotted seasonal changes like the advance and retreat of polar ice. It’s also gathering data of a possible longer trend. There appears to be too much frozen water at low-latitude regions — away from the frigid poles — given the current climate of Mars. The situation is not in equilibrium, said William Feldman of the Los Alamos National Laboratory.
