significant greenhouse effect to warm its surface?

Because there is no use of it's fossile fuels. The greenhouse effect occurs as the natural resources of a planet are depleted.

Kris is right: the atmosphere of Mars has only 0.7% of the surface pressure of Earth. Because of this, Mars' atmosphere is much too thin to reflect heat bouncing off Mars' surface back downwards again. Therefore there is no greenhouse effect on Mars, despite its having mostly carbon dioxide in the atmosphere.

It's true that Mars' atmosphere is mostly carbon dioxide, however, Mars is too small to hold a significant atmosphere. Mars' atmosphere is only 6 mb, compared to Earth's atmosphere of 1000 mb. That's a huge difference!
Also, I don't believe the hype about terraforming Mars. It was too small to hold onto it's original atmosphere so how could it hold a man-made atmosphere?

It is true that the martian atmosphere is mostly carbon dioxide (about 95%), but the martian atmosphere is too thin to trap much heat. Atmospheric pressure on Mars is less than 1/100th that on Earth.

because there is no atmosphere significant enough to be really called "atmosphere". It's just a tiny layer of some gases with almost no pressure at all, it's all evaportaing into space, only a few molecules being held back by the small amount of Marsian gravity.

Mars is too far away from the sun, when the sun goes nova, there will enough heat, to warm the surface, this won't happen for another five million years. when this does occur the polar caps will melt giving rise to oceans. the atmosphere will get thicker and heat will be trapped, then it might be able to support life

Because its atmosphere is so thin - there's not enough carbon dioxide to make much of a difference in its temperature.

1) Is far from Sun
2) Atmosphere is too thin
3) All of the above

there is
its surface get warm at equator almost like on earth
that will be the method alsoo
to teraform mars

because the atmosphere is very thin and the added distance from the sun
