Reply #38: No, it wouldn't

However, in the book the biggest part of the comet (which came apart under the stress of Earth's gravity on the way it, turning it from a cosmic bullet into a cosmic shotgun blast) struck the ocean, punching through the water to the seabed, then smashing through that into the mantle. The impact vaporized cubic miles of seawater. Untold hundred of cubic miles of water were smashed outward at supersonic velocities, making mile-high tsunamies. The impact area, a huge pimple on the face of the globe, is heated to well into the molten range as lava boils up from underneath the earth. For days or weeks, the ocean keeps trying to flow back into the impact area, but even more cubic miles of water are vaporized per hour.

The superheated steam created a permenant super-hurricane as millions of tons of steam per hour is created and floats upward, then spreads and cools. The super-hurricane spins off dozens of catagory-five regular hurricanes in all directions to last at the destroyed coastlines.

Saltwater blasted into the atmosphere falls a rain. At some point, all the water being vaporized at the impact point forms clouds that straddle the planet, making it rain continuously for months. No sun. Flooding. All that fun stuff.

We would have to make greenhouses out of plastic sheeting and wood. We would need grow lights and a source of electricity.

It would be very difficult. 80% fatalities in the first year I don't think is an unreasonable assumption.

Hope you have some Gor-Tex handy, because you'll need it. And a few cases of MREs whouldn't hurt, either.
