here’s one link to NASA.

ASA’s Mars Global Surveyor and Mars Odyssey missions have provided evidence of a recent ice age on Mars. In contrast to Earth’s ice ages, a martian ice age waxes when the poles warm up and water vapor is transported toward lower latitudes. Martian ice ages wane when the poles cool and lock water into polar icecaps.

Driven by solar effects?

Maybe there is Human created global warming but every adherent refuses, as you have, to address the counter argument.

Personally I think the right idea is to put a pocket nuke plant ‘in every one’s back yard and that removes teh entire argument.
