Note that you wouldn't have to accelerate the Earth to escape velocity in order to move it outwards by a few miilion kilometres. Although the energy required would still be vast.

According to current theories the ice ages on our planet are significantly affected by minor changes in the eccentricity of our orbit; changing the shape of our orbit artificially would certainly cause some very significant changes in our climate.
