CO2 Jets Bursting From Martian Ice Cap?

jeffsenter writes "NASA believes this may be the scene on the Martian South Pole as spring-time sunlight heats dust trapped in a layer of CO2 ice, causing it to sublime and ultimately burst through the seasonal upper dry ice layer. Here is the press release based on the findings in visible light and infrared from NASA's Odyssey and Mars Global Surveyor. Actual pictures of the spotting presumably caused by CO2/dust bursts on the Martian pole."

Not bushes

I remember seeing these pictures or ones like them on a "weird science" web site a year or two ago. They thought that the pictures might show bushes growing on Mars. I guess you could consider the CO2 jets to be very fast growing bushes. The jets do seem more plausable though.

Atmospheric pressure

Would this change the atmospheric pressure of mars significantly or even in
the local area of the vents?
