Me, I'm resurecting circa 1961 USAF plans to station large Orion vehicles in high orbit. 4,000 ton space battleships armed with Thiokol "Sprint" booster motors with Casaba Howitzer nuke warheads are just the thing for dealing with threats like this.

The Orion would have to be WAY high orbit, so the EMP doesn't fry all the damn satelites.

Read Niven/Pournelle's FootFall for a fascinating look at an Orion spaceship.

NO no no no no no. NONONONONO!

We need to get together, at the last minute, a team of oil-drillers. Then, we teach them how to pilot a really stupid looking shuttle, and land on the comet in question - because that's easy. THEN, we drill like a really deep hole, and put some super mega awesome 4 gigaton nuke into the comet, and like totally blow it up n' stuff. Yeah.

In all seriousness, I'd love to see some Orions up there.

But at the cost that it would take NASA to do this it would be cheaper to take the hit and try to re-establish society through the evolutionary process.
