The most basic thing we need to happen to the planet is to change it's atmosphere, in other words, thicken it up a bit. This can easily be done by allowing free reign on semi-polluting industries to be set up on Mars.

Given that Mars currently has no way of cycling back and gases into the ground, like Earth's plants and rain tends to do, and it is a bit smaller, I'd say a minimum of 100 years constant effort for a noticeable result.
Think about it, Earth's climate/atmosphere has been under the influence of industry for more than a hundred years, and there is skeptical/plausable proof that we are starting to change or atmosphere for the worst.
