Mars warming?

Here's a National Geographic article regarding Global Warming on the planet except the planet is.... Mars?

I bet you'll never see Katie Couric reporting this on the CBS News.

This has always been my point about global warming. The Sun is not a 60 gizzillion watt GE light bulb that emits a constant stream of energy; it warms and cools. When just a normal tilting of the earths axis results in 100 plus temperature swings is it too much to suggest that maybe, just maybe, the sun might be emitting more energy.

Remember the Ice Age never would have ended without global warming. Unfortunately, Al Gore wasn't around to line his pockets.
