then why are Mars' poles ice melting? Because of bush??

Next time, you're feeling more stupid than normal; that is, BEFORE you ask these ridiculous questions again and show how stupid and uninformed you really are, remember this post. If you forget, not to worry, I will remind you over and over again until you stop asking the question.

"The [Martian] polar cap is receding because the springtime sun is shining on it."

"Here's an amazing fact: The seasonal polar caps are made of martian air that freezes during winter. Depending on the time of year, more than a quarter of the martian atmosphere can be found lying on the ground around the poles. (The atmosphere is 95% CO2; that's why the seasonal polar caps are made of dry ice.)

As seasons come and go, carbon dioxide shifts back and forth--lying on the ground during cold months, floating through the air during warmer months. The world-wide air pressure rises and falls by 25%.
