We are all gonna die between now and a billion years from now. Do I get a cookie for my prediction?

We're overdue for the north american supervolcano basin to explode too. There are near-infinite scenarios which could wipe us all out at any moment. That's just life. It's fragile, so live well and plan contingencies for the things you CAN influence.

The number of people in the world engaged in this search [for catastrophic impactors] totals one or two dozen. How long into the future are you willing to protect Homo sapiens on Earth? Before you answer that question, take a detour to Arizona's Meteor Crater during your next vacation.

If Earth ever suffers a runaway greenhouse effect (like what has happened on Venus), then our atmosphere would trap excess amounts of solar energy, the air temperature would rise, and the oceans would swiftly evaporate into the atmosphere as they sustained a rolling boil. This would be bad.
Neil deGrasse Tyson said:
Eventually, the Sun will swell to occupy the entire sky as its expansion subsumes the orbit of earth. Earth's surface temperature will rise until it matches the 3,000-degree rarified outer layers of the expanded Sun.... But not to worry. We will surely go extinct for some other reason long before this scenario unfolds.
