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.'"

    Hmm, the deniers did not actually have anything intelligent to write, so they just modded you down instead.

    "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.

    "It probably won't be more than 20 years before it's obvious to everyone"

    That sums up most of the climataphobes case. Some conjecture based on short term observations. Go build another model, alright?

    NOTE: I built a lot of models as a kid, but that doesn't qualify me as a marine engineer, an automotive engineer, or even an aviation engineer. Building climate models doesn't qualify anyone to do anything more than to build models.

    I guess it's easier to hit the "I disagree but have no facts with which to rebut" flamebait mod button than it is to actually make a clear rebuttal. Apparently my trailing comment wasn't enough to ward you off. Lolz
