I believe humanity cycles with respect to population numbers. Ever 3600 years this turrible brown dwarf reappears and destroys humanity except for a chosen number (See Noah's Ark and other writings describing this event.). The story has recurred in every writing and religion known today. We probably have until 2087 or 2800- 2900. So enjoy it while it lasts. The 2012 thingy was just to get into the pants of unsuspecting women, milfs, cougars and young college grads.
