We all know that global warming is man made, so I want to know who's been driving their SUVs on Mars?

Mars is still nothing like Earth, but earthquakes and global warming may be changing the face of the Red Planet, new NASA photos taken from orbit suggest...

The latest findings, made by comparing photos taken by a camera aboard NASA's Mars Global Surveyor spacecraft, were announced yesterday.

"What the Mars orbital camera has revealed from this long and detailed study of the Red Planet is a dynamic Mars, a planet that can change � not on the mind-boggling millions and billions of years, but on the order of years and decades," said Michael Meyer, chief scientist for NASA's Mars Exploration Program...

Placing photographs side by side, researchers at the company discovered mysterious gullies appearing on the walls of sand dunes in less than three years, tracks from boulders that had tumbled down the steep wall of a crater between November 2003 and December 2004, dramatic melting of ice at the south pole over three consecutive martian summers, and even a meteorite crater that hadn't existed 20 years ago...

At Mars' south pole, an escarpment of frozen carbon dioxide has retreated nearly 10 feet a year over the past three summers.

"It's evaporating now at a prodigious rate," said Malin.

The significance of this is Mars is experiencing climate change, or has experienced climate change."

Why Mars may be warming is a mystery, he said.

Oh really? Maybe it has something to do with increased solar output. The output of the sun is higher now than at any time in the last 1000 years. Considering the sun is where we get ALL of our energy, maybe.. just maybe, that has something to do with it.

Of course if you admitted that, you might also have to admit that it's also what's caused global warming here on Earth.
