Why are the ice pole areas on the Mars becoming smaller and smaller?

The evidence is not conclusive on whether or not Mars is experiencing any long-term warming spell - there is not good evidence to show that it is warming globally either, for that matter. Mars' climate is largely determined by albedo changes, and there is no discernible secular trend regarding albedo:

That being said, the only other two major factors affecting any planet's climate are its own Milankovitch cycles and solar output. The former being local and only applicable to that planet, the latter would be the only one that could be extrapolated as an explanation for trends in other planets. Since however we have measured no increase in solar output in the last 30 or so years, solar output has not caused any warming (sic) on Mars. Nor has it been responsible for any of the warming on Earth within the past few decades.

Climate sciensts most certainly do not say there is heating on Mars related to a solar cause.

There has been no increase in solar output that would explain warming on either Earth or Mars over the past 30 years.

There is no evidence that Mars warming or that its's ice caps are getting smaller. Mars' ice caps grow and shrink with the seasons.

Climate scientists say Mars heating is related to a solar cause. Solar influence has been eliminated as the cause of warming on earth

i guess the suns heat must miraculously just go right on past earth and straight on to mars, makes perfect sense to me, but then i flunked out of kindergarten

Mars' albedo is changing due to wind blown dust

however this effect is/was local not global

Jerry: solar variation is also related to planetary orbit. The orbits of the planets are not perfectly circular and change over time. When a planet moves closer to the Sun solar input increases, when it moves farther away solar input decreases. Orbital variations are what is known as Milankovitch Cycles. These cycles affect the amount of solar irradiance striking and warming the planet.

The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet's orbit and tilt, not by changes in the sun.

It is because of the SUV's on Mars same as here on Earth.

Climate scientists say Mars heating is related to a solar cause. Solar influence has been eliminated as the cause of warming on earth and numerous other planetary bodies in our solar system.

It's pretty simple actually - if you are in middle school. But, you're probably one of those people who lamed their way through school and think that it is hip to be stupid, huh?

Busted, I had intended to say that had a few years ago tha had been suggested, but I apparently blacked out for about a sentence and a half.

Nevertheless, warming patterns on mars and earth are not isomorphic or results of the same cause.

"Martian" made global warming, little green men in little green cars.
