Scared? No. Trying not to laugh? Yes.
What you need is our handy 15-part translation guide for interpreting what the crackpots say about 2012. Print it out and keep it handy when visiting woo-woo websites or watching the History Channel.
1) Statement: "Scientists say..."
Translation: "No scientists say. We've made it up, which is why we don't specify which scientists."
2) St: "NASA has confirmed..."
Tr: "NASA has not confirmed..." See 1) above.
3) St: "Planet X/Nibiru is only visible from the South Pole."
Tr: "We assume you're too stupid to realise that anything visible from the South Pole is also visible from Australia, South America, Southern Africa..."
4) St: "Planet X/Nibiru was discovered by the IRAS satellite in 1983."
Tr: "The object seen by IRAS was eventually confirmed to be a distant galaxy, but we've ignored all later reports because they disprove our claim."
5) St: "There will be a rare alignment between the Sun and the galaxy."
Tr: "There will be no alignment between the Sun and the galaxy which doesn't take place every single year."
6) St: "There is a blank area on Google Sky which hides Planet X/Nibiru."
Tr: "If you look at this area of the sky with your own eyes, you will see no sign of this object, but we don't like to mention that."
7) St: "Many ancient predictions point to this date."
Tr: " No ancient predictions point to this date. They've all been made up in the last few years."
8) St: "The Earth's poles will reverse in 2012."
Tr: "We don't really understand the difference between rotational poles and magnetic poles. If we'd studied geophysics we'd realise that a magnetic pole shift takes thousands of years and a rotational pole shift is a physical impossibility."
9) St: "The Earth will be destroyed by a solar flare."
Tr: "We haven't studied solar physics either. If we had, we'd understand that solar flares are no threat to life on Earth."
10) St: "The planets will align."
Tr: "We hope no-one will try running some software which simulates the positions of the planets because they'll find out we're lying again."
11) St: "Join our forum and share information about 2012. Anyone posting debunking messages will be banned."
Tr: "We don't want anyone spoiling our world of delusion and fantasy with real scientific facts."
12) St: "The surface of the Sun will be disrupted by a 'barycentric sleeve'."
Tr: "We'd like to blind you with science, but we don't know anything about it so we'll just invent some meaningless claptrap in the hope you'll fall for it."
13) St: "No-one knows what will happen in 2012."
Tr: "We do know what will happen in 2012 - absolutely nothing."
14) St: "Earthquakes, tsunamis, fire, flood, millions will die...."
Tr: "We like to appear knowledgeable and important and we don't particularly care if we terrify kids and cause people to commit suicide."
15) St: Support our advertisers and buy our books/videos/survival kits.."
Tr: "We know our predictions are garbage, but we'd like to rake in as much of your cash as we can in order to fund our comfortable retirement in 2013."
