A question for the astronomers in the audience...

How much longer would the Earth's orbit around the sun have to be for (most of) the planet to be uninhabitable?

Would 10% do it? The poles get pretty damn chilly as it is, if we added another month in there between December and January, would the whole of Europe be similar?
