A new research suggests Mars had a dustier, stormier atmosphere. Mars climate was probably a lot like the American Dust Bowl of the 1930s or even worse. The evidence comes from the discovery of a huge underground reservoir of dry ice, or frozen carbon dioxide, at its south pole. They suspect some of that store of carbon dioxide was once in Mars atmosphere, making it denser.Mars atmosphere, made up mostly of carbon dioxide, is many times thinner than the top of Mount Everest on Earth. Maze of gullies, canyons and river channels on the surface points to a warmer and wetter past very early in the planets history.
