http://www.drewexmachina.com/2014/10/02/the-fate-of-comet-halley/ Well based on this article the precise orbit of Halley cannot be predicted beyond a revolution and a half, therefore its future orbit cannot be predicted. The introduce a variable known as the Lyapunov exponent which sets a maximum limit on predictability.

http://nationalreport.net/halleys-comet-hit-earth-2061-experts-warn/ Not sure if this is some misguided repurposed bovine waste, or actually real. In 2061, Halley's Comet has an 80 Percent Chance to hit Earth, causing another mass extinction- this is because of a perturbation from Uranus, whose gravitational impact was the strongest due to the "Puck Effect". Not sure if this is actually a thing, but the "Puck Effect" is a effect that occurs when Puck, a moon of Uranus, gets a lower orbit, and increases Uranus' net gravitational influence. And this is not a conspiracy website either, reporting this. The Guardian reported on this too.
