Several months ago I had an article on how to survive ginormous solar flares. Mostly just keep your electronics that count in a Faraday cage (metal container), and have some batteries around for them. Solar flares aren't a big deal for people, only for electronics, but you might want to get some lightweight long sleeve shirts and a big hat if you are worried about sunburn.
In the event that there is a comet smackdown, though, the strategy would be different. There have been several comet smackdowns in the past, for example some people think the Dark Ages were caused by one or more comets slamming into the Earth.

There are also accounts of the whole sky being on fire, and that sort of thing, from late antiquity Rome etc.
The comforting thought is that humanity has managed to bounce back from the comets in the past, because we're still here. But comets have spelled the end of several major civilizations, along with a major culling of the population each time. It seems comets do this about every 3600 years or so, and we're about due for another smackdown, in 2012 or soon thereafter.
The reason why a comet bombardment is so devastating isn't so much the destruction to property by falling debris as it is the large amount of dust and smoke that ends up in the air for several years on end, which stunts plant growth and causes famine and disease. The evidence is borne out in tree rings as well as history. Sometimes comets only affect one part of the world and then there's contemporary writings about "bread failures" and such.
I am wondering if the people who are making chemtrails might be better employed figuring out how to precipitate the dust from comet smackdowns out of the air faster. They might be able to save more of humanity. Of course, from what various elites have said on the record, I think they would rather have most of us die. Maybe they think they'll survive in those giant bunkers they've built everywhere, then come out when the dust settles and be in a position to rule the rest of us, probably with less politeness than before. With the stories that come out of alien or military type abductions that all seem to involve medical experiments or genetics, and the various attempts at population reduction through GMO food, sneaky sterilization or infection with disease by fake vaccines in the third world, etc., it's possible they also think they will replace us with something else "new and improved".
With this in mind, if you don't have some big underground bunker of your own, here's my thoughts how to survive the comet smackdown that is probably coming soon:
1. If you are just out and about and stuff starts falling from the sky, get as far underground as you can - like if you are in a city and there's a subway, go there, or go into the basement of whatever building you are in or near. Think about places to go take shelter in that are near where you frequently go. Practice going to them, so that you don't have to think hard when the time comes. Train your spouse and kids to do the same. Carry on or near you, a dust mask or an equivalent (bandannas etc.). Perhaps there is a chance of weird electromagnetic things happening too - lightning, etc. so being underground in that event would be good. Carry a little flashlight. If you're in a basement and the lights go out, you'll be glad you had one.
2. If you have the luxury of moving now, seek the high ground. I am guessing that the chance of actually being hit by a falling rock from the sky would be small, but that the resulting fires, shock waves from the impacts, tsunamis, etc. would be significantly more of a risk. If a tsunami were big enough, it would throw water further inland than a regular storm, so you would want high ground. I would also add, if you can be both on the high ground and near a drinkable source of water like a mountain stream or spring, so much the better. You can be both on the high ground and underground at the same time, if you can dig. I would also choose to be near a small town that is within 10 or 20 miles of a hospital over a city or a really remote place.
3. Food and water. Starting now, carry food you don't have to cook for 2 or 3 days and maybe a half gallon of water on you (minimum). But water is heavy, so carry some and have more around where you will usually be. Put bottled water in your car and stash some at work. You can do the same with the food, but at home, stockpile a lot of canned and dry food and water, because not only will there be a great disruption of the supply chain, but there will be problems with crops for several years after. You might want to hide a lot of this food so that looters won't get it all, and just have some out. Don't brag to your neighbors about your food!
Not only get regular shelf-stable food, but if you can't afford freeze-dried food, which is 3 times the cost of regular food, consider dehydrating regular food yourself and storing it with oxygen absorbers and with as little oxygen as possible. You can make your own oxygen absorbers by putting steel wool and salt in a little cloth pouch (just use a piece of cloth and put a twist tie on it). Store your food in 5-gallon buckets from the hardware store (with lids), unless you can get free buckets - and perhaps also in mylar pouches, if you can afford them. You can get oxygen out of your food containers by putting dry ice on top, waiting a little while and then closing the lid. Carbon dioxide is heavier than air so it'll fill the top of the bucket. You can make a solar/air dehydrating shack, about the size of a doghouse or an outhouse, and not need power to run it. This will dry a lot of produce at once. You could make it out of pallets and an old window for almost free. If you can't make a big thing like that, you can make a small dehydrator out of a small lamp with an old-style light bulb poking into a cardboard box with a lid, and some old screening for shelves. Get one (or more) gravity water filter, and learn how to make one out of sand, clay, charcoal etc. so that when your filter runs out you can make another one. Also, get a water barrel or some kiddie pools so that you can collect water to drink, irrigate, etc. Or dig a well, or at least learn how to dig a well. A well with a hand water pump would be a great thing to have.
If you can afford it, you're of a fertile age, and you want to stay fertile, store home grown food that you know isn't GMO or treated with pesticides. If you know nothing else, then know this: Just avoiding all prepackaged food as much as you can is a big step. Cook from scratch and don't eat corn or soy unless you know for certain it's not a GMO variety. However, if you are curious, there's a couple links to GMO news on the news page. They keep coming out with more GMO stuff, like salmon for example. For now, wild-caught salmon is still safe.
4. Seeds. Store some heirloom seeds. You might not be able to grow crops effectively for a few years after a comet smackdown. You could try, but the reduced sunlight and/or weather disruptions might make it a non-starter. If you were fabulously wealthy or a government you could get some kind of small nuclear reactor and power grow lights in your bunker underground, but since we're just average Joes and Janes here, you want to store seeds in a way that they will keep for 5 or 10 years. Freezing them is good, but we can't be assured of having power. The best we can probably do is keep them in a cool, dark place and keep them dry. You can freeze them for now, and maybe your area won't be affected by power outages. Maybe we can be reassured that Bill Gates and Monsanto have built a big seed bank in Norway, but somehow I don't think that's for us. There are other seed banks, too. Also consider learning about edible weeds, because those plants might be better able to survive without irrigation, lots of sun, etc.
5. Security. If you want to stay in your home, which might be easier than running off to somewhere else, you will want to make bars for the windows, for across the door, etc. You can pre-fab these in sets now and just keep them around, then install them when you think you need them. Re-bar is okay, but if you don't have the tools to cut re-bar then try conduit. It's better than nothing, and they make clamps etc. for conduit so you can fasten it to wood.
I suggest you also arm yourself and learn how to use your weapons; and hide a few of them so that if the one you carry is stolen you can re-arm yourself later. You may need to defend yourself from looters. Guns aren't the only weapons in the world. Practically anything can be used as a weapon. But do consider getting a conceal carry license - follow the law. No need to get jailed for something stupid while society still works. And of course, use discretion.
I also suggest that you stockpile dog food. Even if you don't want to have a dog now, you can always acquire one (or more) later as a guard dog, and you will be able to feed it then. There will probably be a lot of stray dogs running around after a disaster. The strays will get feral after a short while, so it might be better to adopt a stray dog sooner than later after a disaster. Also, people might start to eat the stray dogs and cats if they get hungry enough, so eventually there might be no dogs around. If you have land, consider things like trip wire alarms, booby traps, etc. for when things get rough. It will be hard for someone to live alone and survive. You will have to learn how to work in a group, if only for the reason that you have to sleep sometime.
6. Utilities. Store propane, lamp oil, wood, candles, and get a wood burning stove. If you can't afford a wood burning stove, you can build a rocket stove from clay you get from the ground, rubble, a metal barrel, and furnace parts. Get a battery powered carbon monoxide alarm if you are going to experiment with that. You can make a primitive fridge from two large clay pots, one inside the other, with a lid and wet sand between them. When choosing a place to live, if you are going to build something, keep in mind that a small place is easier to heat, and that underground it stays around 50 degrees F year round.
7. If the comet disaster leaves your area sort of "walking wounded" and then it looks like you will face a lot of social chaos, troops, etc., the best bet for survival is to hide, blend in, try to stay calm, avoid armed conflict if you can, pretend to acquiesce to authority, but then do your own thing when they're gone. If it gets too nazi-esque, then slip away, hide, lie, whatever you need to do. Nobody has the right to be a nazi to anyone else. Everybody has the right to live and be free.
8. Once things settle down, you will need a profession that actually produces something or is useful in the smackdown world. If you don't know how to do something useful, learn now.
