Global Warming on Mars?
A study of the ice caps on Mars may show that the red planet is experiencing a warming trend.
After decades of thinking that the ice caps on Mars were mostly carbon dioxide (dry ice), planetary geologists are starting to think that those caps may be mostly fresh water ice instead.
Caltech planetary scientists have been keeping a close eye on the dozens of deep, wide pits in the southern martian ice caps. These pits have been growing larger every year, but they never get any deeper.
The scientists believe this means that there is a layer of dry ice that is evaporating off of a thicker layer of water ice. The yearly increases in evaporation may be caused by a global warming trend happening on Mars.
If both Mars and Earth are experiencing global warming, then perhaps there is a larger phenomenon going on in the Solar System that is causing their global climates to change.
Does Al Gore know about this??
