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.'"

    Global climate change on Mars certainly helps corroborate the idea that our own climate changes might be natural. The mysogenistic anthropomophists haven't had the last say.

    BTW - if you're worried about man's impact on the environment, get off your buttocks, and plant some trees. Trap some carbon. Think of the children.

    Or you can, you know, do math.

    Apply the inverse sqr law to the rise in temperature and how it would impact the temperature change on ifferent planets.

    Also not if it was the sun it would be happening to ALL bodies in the solar system, and it is not.

    Next.

    Yes, we are experience and increased global changed due to the millions of tons of CO2 we spew into the air every day.

    The climate change we're observing on earth has happened in less than 100 years.

    You're full of shit.
