Mars images hint at recent climate swings
New Scientist Space ^ | 10/16/06 | David Shiga

A dust layer sandwiched between layers of ice near Mars's north pole suggests the planet's climate has shifted dramatically in the past 100,000 years or so, reveal images recently obtained by NASA's Mars Reconnaissance Orbiter (MRO).

Previous research has suggested that the tilt of Mars's axis of rotation fluctuates from 10° to 40° with time, leading to major climate shifts (see Wrecking ball could break the ice on Mars).

Now MRO, which started returning close-up images of the Red Planet in late September, has provided new evidence that Mars's climate has undergone major shifts relatively recently.

Global Warming on Mars? Bush's and Halliburton's fault.

Are you finding the new images on the MRO website? I've been watching for them but I'm not seeing anything new there. I see photos from the MRO but they're always at other sites.

Damn! Now I'll probably have to pay some Mars road tax to drive my SUV up there!

I'd be curious to know if the Mars climate shifts over the last 100,000 years correspond to the timing of the same events on Earth. So much for "global warming theory" if that turns out to be the case.

But if it corresponds to Earth paleoclimactic cycles, that would mean that the Martians and Earthlings were coordinating efforts. But then, communications were lost in the Earth's stone age, and on Mars, something went horribly wrong...
