Radar Map of Buried Mars Layers Confirms Climate Cycles

Matt_dk writes "A radar instrument on the Mars Reconnaissance Orbiter has essentially looked below the surface of the Red Planet's north-polar ice cap, and found data to confirm theoretical models of Martian climate swings during the past few million years. The new, three-dimensional map using 358 radar observations provides a cross-sectional view of the north-polar layered deposits. 'The radar has been giving us spectacular results,' said Jeffrey Plaut of JPL, a member of the science team for the Shallow Radar instrument. 'We have mapped continuous underground layers in three dimensions across a vast area.'"

Re:Global Warming

"global warming" actually confuses the issue because climate change doesn't evenly modify the temperature of our climate. In fact, some areas of the globe have cooled of late

That's a stupid thing to say. Globally the temperature effectively rises, that's the main trait of the change being talked about. But a number of cretins out there can't see that "global" doesn't imply "uniform". That it gets colder in some places is irrelevant.

By the way, in France it was always called "climate warming" (le rechauffement climatique), even back in the 1990s, when only scientific literature would talk about it. It was never very politicised there anyway, since no one there was enough of a dumbass to consider debating a scientific consensus.
