Crop Circle 2009 Decoded : The changes have begun

Series of crop circles through recent years that have been decoded pretty sufficiently in my opinion as to be a message of Nibiru's impending passage through our solar system this year. A very important and timely message for humanity and hope for its survival...so pay attention.

The Arecibo Message Revisited

The Arecibo message
http://en.wikipedia.org/wiki/Arecibo_message

Then one year later, in August 2002, another impressive formation was discovered just to the west of Winchester (only about 8½ miles to the southeast of the Chilbolton formations). An "alien face" with a circular grid containing a coded message.

When the code is broken, it reads:

"Beware the bearers of false gifts & their broken promises. Much pain but still time. There is good out there. We oppose deception. Conduit closing."

Are these circles genuine? We cant know for sure, since no one investigated them to see if there were significant crop/soil anomalies. But they do seem very sophisticated.

How should we interpret this possible response? And what about the coded message?
