Will Earth Ever Be Unlivable?

Four billion years from now, the increase in the Earth's surface temperature will cause a runaway greenhouse effect, creating conditions more extreme than present-day Venus and heating Earth's surface enough to melt it. By that point, all life on the Earth will be extinct.
How much longer will the Earth last?
