Martian Ice Caps are Eroding
New photos taken by the Mars Global Surveyor are tracking the changes to the Martian polar ice caps, and from what scientists can tell, they're shrinking. If true, this would indicate the Mars is warming up, and it's atmosphere is becoming more dense. In fact, if the erosion of the carbon dioxide ice continues, some scientists predict that Mars could become significantly warmer in just a few thousand years. Other scientists urge caution, though, pointing out that we don't have enough data to confirm climate change.
